11 Best free and paid second phone number apps for Android

Trying to find the right second phone number for Android, but not sure where to start?

The fastest way to get a second phone number on an Android phone is a second phone number app. Download and install one from the Google Play Store, select a local number, and start making calls. You can get started in less than five minutes and don’t need an extra SIM card. 

Free apps are a good option for personal use, but they lack business-friendly features. Some providers restrict access to a number if it isn’t active. Paid business apps start around $15 per user per month and add shared numbers, call recording, and CRM connections. You can access numbers with these providers as long as you have an active subscription. 

The other route is a second SIM or eSIM line from your carrier, which costs more but behaves like your primary number. The downside is you can’t share this number with a team, so it’s a non-starter for businesses.

This guide walks through the 11 best second phone number apps for Android phones. Once you read through their features, limitations, and prices, you can download your preferred choice immediately if you like what you see.

• Choose Quo if you want to share a business phone number with a team. Access your second phone number on multiple devices. Handle your customer communications simultaneously with your team. 
• Choose Google Voice if you’re a single user already using Google Workspace. Integrate with Google apps like Calendar and Meet. 
• Choose Burner or Hushed if you want a temporary number for personal use. You can sign up for both providers on the web and use their numbers on your phone. 
• Choose 2ndLine or TextFree if you need a second number for personal use and don’t mind viewing ads. 
• Choose a carrier-based dual SIM phone line if you need a phone number to use for verification codes and can work without an internet connection.

Breaking down the top second phone number apps available on Android

If you’ve already tried one app and ready to switch, you know not every second phone number app is created equal. The worst ones keep you from working efficiently, while the best ones can help you build better relationships with your customers.

Here are the 11 best second phone number apps available on Android, starting with the #1 business phone platform on G2.

1. Quo, formerly OpenPhone

Pros

• Easy to add numbers and teammates as your business grows
• Intuitive user experience
• Cost-effective for growing teams
• Call recordings are stored in context

Cons

• Does not support mass texting
• Receiving two-factor authorization texts can’t be guaranteed*

* Keep in mind this is a limitation with all second number apps. In many cases, two-factor authentication services don’t allow virtual phone numbers to be used during the registration or verification step.

Quo is a virtual phone system built to help you build meaningful relationships with your customers effortlessly. Your team can use Quo from any Android cell phone. You can also use it with laptops, computers, and iOS devices like iPhones and iPads. 

Quo can easily scale with you as your team grows. Each user on your plan comes with one free local US, Canadian, or North American toll-free number. And if you need more, additional phone numbers are $5 per number per month. 

You can assign each of your teammates their own Quo number. Plus, you have the option to also add multiple team members to a single shared number, which lets everyone on your team share responsibility for incoming calls. 

Compared to other second number apps for Android, Quo lets you easily build a professional phone presence for your business. You can:

• Never miss an incoming call with Sona, our 24/7 AI answering service. Train it on your documentation so that it provides your callers with accurate responses. 
• Set up self-service phone menus to help customers reach the right member of your team.
• Add business hours to your phone number so you don’t get notifications while off the clock.
• Easily record any phone call and playback recordings later in context with the rest of the conversation.
• Host three-way calls from your Android phone for collaborating with your team and handing off callers to your others.

Quo can also help you save time you’d otherwise spend on repetitive tasks. You can use auto-reply texts on your Android device to automatically message contacts if you miss their calls. Set up templated text message snippets to instantly reply to frequently asked questions. 

You can even connect the apps you already use to Quo, including Slack, HubSpot, and Google Contacts, to automate specific workflows. And with our Claude and ChatGPT integrations, you can get your preferred AI chatbot to analyze your calls, reply to customers, and update your address book in seconds. 

Join thousands of businesses who choose Quo as their phone provider. We’re rated #1 on G2 for customer satisfaction. 

“Quo’s product is much more user-friendly. The iPhone and Android apps seamlessly integrate with all peripherals, and the connection quality is great. The desktop app makes texting customers super easy.” — Mike Gaspar, Chief Operating Officer, HealthCasa Limited

2. Line2

Pros

• Can make unlimited calls and texts in the US
• Unlimited text messages

Cons

• The Android version may be buggy, according to user reviews
• Not built for team use
• No ability to purchase additional phone numbers

Line2 is a second phone number app that primarily catered to small business owners but pivoted to personal usage. You can either port an existing number to the platform or buy a brand-new number with a local area code.

But the features you get with a Line2 plan are relatively bare-bones. You can’t make international calls at all, and there’s no way to share a single phone number with the rest of your team.

Plus, Line2’s prices come with many additional fees, including:

• Administrative and compliance cost-recovery fee
• Federal universal service recovery fee

Line2 key features

• Unlimited calls in the US and Canada
• Unlimited SMS and MMS in North America
• Voicemail transcriptions
• Call forwarding
• Caller ID

Line2 pricing

Line2 has one plan with two billing options:

• Annual: $7.99 per month
• Monthly: $9.99 per month

3. Google Voice

Pros

• Free version is available for personal users in the US
• Unlimited calls in the US and Canada

Cons

• Texting is not available to customers outside the US
• Google Voice for Google Workspace is only available in select countries
• Google Voice’s free version is not equipped for business use

Google Voice is a VoIP phone service with plans for personal users and business owners. You can sign up to get a free second phone number for personal use if you’re based in the US. However, if you need more business-specific features or are located outside of the United States, you can sign up for Google Voice for Google Workspace. Business plans start at $17 per month per user, including the cost of Google Workspace.

The free plan of Google Voice is significantly limited. For example, you can’t access call recordings without a separate call recording app for Android. You also can’t separate your contact lists, which means you won’t be able to tell if a call is work-related or not. Porting an existing number costs $20, plus an extra $3 to port the number out. And keep in mind you can only have one number at a time.

Google Voice for Google Workspace comes with its own set of limitations. You can only have up to 10 users on the basic plan, and essential business features like auto-attendants and ring groups aren’t available unless you upgrade.

Google Voice key features

• Unlimited calls in the US and Canada
• SMS and MMS support
• Integrations with Google Calendar and Google Meet
• Automatic call recordings, requires an upgrade
• International number support, requires a paid plan

Google Voice pricing

Google Voice pricing includes four plans:

• Starter without Workspace: $10 per month, limited to one user, for call recording, three-way calling, voicemail transcription, and mobile and web apps
• Starter: $10 per user per month, with a 10-user maximum, for calls and texts in the US, call forwarding, and SLAs
• Standard: $20 per user per month to access on-demand call recordings, ring groups, and phone menus
• Premier: $30 per user per month to access automatic call recordings and advanced reporting

Besides the first plan listed above, the other Google Voice plans require a Google Workspace subscription, which starts at $7 per user per month.

4. Hushed

Pros

• Flexible pricing plans
• Custom voicemail greetings

Cons

• No access to shared numbers
• Requires an upgrade for unlimited minutes
• Glitches with app notifications
• No third-party integrations

Hushed allows you to put multiple phone numbers on one Android device. It’s a great option if you’re looking for a temporary phone number for personal use. 

However, Hushed doesn’t offer the basic features provided by most other second phone line apps. For example, you can’t access call recordings or auto-attendants. Plus, there’s no unlimited talk and text unless you pay for an Unlimited Subscription. If you spend lots of time on the phone with your customers, Hushed can get expensive fast. And if you want to reach customers outside the US and Canada, keep in mind you have to buy separate bundles for international calls.

Like a few other apps on this list, Hushed is rife with bugs and glitches. Many users mention notifications don’t pop up at the right time. This can be a dealbreaker to small business owners who need to communicate with customers quickly. 

Here’s a recent review:

“I use this for my business (I like to keep my personal number private) and I’ve lost out on a few clients due to Hushed never sending me notifications that I’ve gotten a text. I even periodically check the app, and no new texts will show. But hours, sometimes DAYS later they pop up with the date it was supposed to send. This has happened three times now, at this point I’m looking for another app.” — Google Play

Hushed doesn’t let you share your second phone number or integrate with third-party tools. Without these features, it’s a non-starter for business use. Keep that in mind as you consider your second phone number options.

Hushed key features

• Voicemail greetings
• Call forwarding
• Auto-replies
• Call routing

Hushed pricing

Hushed offers three pricing plans to choose from:

• Prepaid: Starts at $7.99 for limited talk and text, with 7, 30, 90, and 365-day plans available
• Unlimited: Starts at $6.99 per month for unlimited talk and text, available for one to three numbers
• Pay-as-you-go: Starts at $8.99 per month to use Hushed credits for international calls and texts

5. Sideline

Pros

• Unlimited calls and texts in the US and Canada
• Automatically detects spam calls

Cons

• Calls and texts could burn through carrier minutes
• Does not support mass messaging
• Group messaging is limited to 10 users max
• Can’t get all features on one plan
• No international calling

Sideline is a second phone number app designed for Android and iOS. Once you download the app and pay for a plan, Sideline defaults to making calls and texts through your existing carrier plan. If you’re using pre-paid minutes or a limited plan, you need to disable this feature in-app so you don’t wind up paying overage fees.

You can use Sideline to access some modernized features, including auto-replies. Unfortunately, that’s about where its functionality ends. For example, you can’t integrate with tools you’re already using, or record incoming calls for legal purposes. There’s also no way to purchase toll-free numbers at all.

The biggest limitation of Sideline’s system? You can’t get all the same features on the same plan. For example, you can upgrade to a Team Number to share a line with your coworkers, but you lose this feature when upgrading to Enterprise. You also can’t make international calls on any plan.

Sideline key features

• Auto-replies
• Voicemail to text
• Group messaging
• Free calls and texts in the US and Canada
• Separate caller ID

Sideline pricing

Sideline’s pricing depends on how long you want a subscription. Your options include:

•  Monthly: $14.49
•  Half Yearly: $69.99 
• Yearly: $129.99

6. Burner

Pros

• Easy to delete phone numbers after use

Cons

• Not built for business use
• No integrations
• No call recordings
• No auto-attendants
• Not always reliable or user-friendly

As the name implies, Burner offers secondary phone numbers you can use and eventually ‘burn’ or discard. Burner is currently available on iPhone and Android devices, although only phones are supported — there’s no desktop app available.

Most users rely on Burner to call and text anonymously, then delete numbers when they’re done to protect their privacy. However, this doesn’t benefit business owners looking to build relationships with their customers. You won’t have access to integrations at all, and you can’t get business phone features like call recordings and auto-attendants. There’s also no way to collaborate with your team since you can’t create shared numbers.

And according to recent user reviews, the Android app doesn’t always work as intended:

“Glitchy, drops calls, sometimes it rings or the notification sounds, sometimes it doesn’t. The worst part is I don’t receive all of my messages. The ones I send appear as though they were sent, but not all of them make it. It’s worse on the inbound [than] outbound. If it worked, it would be a good app, but it’s too inconsistent. Just my experience.” — Burner review on Google Play Store

Burner key features

• Unlimited calls in the US and Canada
• SMS and picture support
• Auto-replies
• Call blocking features
• Spam filters

Burner pricing

Burner’s pricing plans depend on where you purchase them:

• Web Standard: $3.99 per month for one number purchased on the web, billed annually
• Web Premium: $5.83 per month for one number, video messaging, AI voicemail transcription, VPN, and reverse number lookup, billed annually
• Play Store: $4.99 per month for one number purchased from the iPhone app, billed annually

7. Grasshopper

Pros

• Pay per number, not per user
• Buy or port local and toll-free numbers

Cons

• Additional numbers are more expensive than other providers
• No international text messaging
• No integrations with third-party apps
• No call recording options

Grasshopper provides multiple phone numbers to solopreneurs and small business owners. The Solo plan comes with one toll-free or local phone number, as well as three extensions so you can forward calls to other devices.

But Grasshopper’s pricing for additional numbers is much higher than other providers. For example, additional phone numbers cost $9 per number per month. Most other providers, like Quo, offer additional numbers at $5 per number per month. 

Plus, Grasshopper doesn’t make collaboration a major part of its platform. Apart from not having any shared numbers, you can’t message internally, share the same contact inbox, or record your calls for future context.

If you want a business phone system with better collaboration features, you’re better off looking for a Grasshopper alternative.

Grasshopper key features

• Unlimited calls to the US and Canada
• Unlimited business texting
• Multiple phone numbers and extensions
• Call transfers
• Auto-replies for first time new callers

Grasshopper pricing

Grasshopper’s pricing offers three different plans you can choose from:

• True Solo: $14 per month for one user, one phone number, and one extension
• Solo Plus: $25 per month for unlimited users, one phone number, and three extensions
• Small Business: $55 per month for unlimited users, four phone numbers, and unlimited extensions

8. Ooma Office

Pros

• You can make unlimited calls within North America
• Option to play music while your caller is on hold
• Offers features like analog fax and overhead paging

Cons

• Reports of poor call quality
• Texting requires an upgrade
• Call recording requires an upgrade
• Voicemail transcription requires an upgrade

Ooma is an older VoIP provider designed to serve both home and business owners. Apart from their landlines and home security devices, they also sell small business phones and a VoIP platform.

Most of Ooma’s features were designed for physical businesses. For example, overhead paging and intercom support doesn’t make sense for distributed teams. Plus, you have to upgrade to the second most expensive plan just to access basic features like texting and call recording.

Unfortunately, Ooma’s second phone number for the Android app doesn’t receive regular updates. Many users complain about poor call quality and say it’s difficult to get in touch with customer support. See for yourself in these recent reviews:

“Actually, the worst experience I have ever had with an app. My company had constant issues with them, and when we’d report, it was 50/50 on whether customer support could actually help you. My calls would randomly drop all the time with full service. As you can imagine, that’s not great for a company to have happened. My messages wouldn’t always send, and when I would try and open my messages, they wouldn’t load, so I would have to force close the app. I have more issues, but I’m out of characters.” — Ooma Office review on Google Play Store

Ooma key features

• Unlimited calls to the US, Canada, and Mexico
• Auto-attendants
• Local and toll-free numbers
• Music on hold
• Digital faxing

Ooma pricing

Business owners have three plans to choose from:

• Office Essentials: $19.95 per user per month for virtual receptionists, simultaneous ring, and music on hold
• Office Pro: $24.95 per user per month for the desktop app, text messaging, and call recording
• Office Pro Plus: $29.95 per user per month for call queuing, team chat, hot desking, and CRM integration

9. iPlum

Pros

• Compatible with Android phones, tablets, and Chromebooks
• HIPAA compliant

Cons

• Essential business features like voicemail to email and call recordings cost extra
• Requires you to upgrade for unlimited calls and texts

iPlum is a mobile VoIP service built for healthcare companies. You can use their HIPAA-compliant system to buy a number to use on your own or set up a team account that everyone can work from together.

While iPlum offers more features than free second phone number apps, it can still be restrictive as your business grows. Call recording is only available on their highest tier. And SMS archives are only stored for 12 months. Plus, even though shared numbers are available, there aren’t any other built-in collaboration features available for your team. And since iPlum doesn’t integrate with third-party apps, you can’t push data to other platforms to keep everyone in the loop.

iPlum key features

• Set business hours
• Call transfers
• SMS and MMS support
• Auto-replies
• Shared phone numbers

iPlum pricing

iPlum’s pricing includes three distinct plans:

• Standard: $8.99 per user per month for calls and texts in Canada and the US, business hours, auto-replies, phone trees, spam blocking, voicemail, and mobile apps
• Professional: $14.99 per user per month for signed BAAs, voicemail transcriptions, text templates, scheduled texts, one year of text archiving, and web app support
• Enterprise: $25.99 per user per month for toll-free numbers instead of local numbers, call recording and consent announcements, 10-year storage for call recordings and texts, and live support via Zoom calls

Best free Android second phone number apps

Now that we’ve walked you through the best paid apps, here are a couple of free options to look at:

10. 2ndLine

Pros

• International calling is available
• Mobile phone and tablet support

Cons

• Banner ads run in the free version of the app
• Only available for Android
• No features specifically for business use

2ndLine is a VoIP app for Android developed by TextNow. Once installed, you can add an alternate number to any Android tablet or mobile phone. As long as you’re connected to WiFi, you can call or text contacts anywhere in the US.

Unfortunately, the free version of 2ndLine comes with in-app ads. Many users mention they may affect the quality of your calls. Check out this recent review:

“This app can be sluggish and unresponsive, which seems to happen when the ads are pouring in. Also, the aforementioned ads can be frequent and intrusive. They may appear during a conversation, and will occasionally disconnect your call.” — Google Play

You need to make at least one phone call a day to prevent your account from becoming inactive and getting recycled — in other words, removed from your account and given to someone else. .

2ndLine is only available from app stores in the US and Canada. If you’re outside either country, you need to look for a 2ndLine alternative.

2ndLine key features

• Unlimited free calls in the US and Canada
• Supports group messaging
• Call forwarding
• Voicemail recordings
• MMS supported

2ndLine pricing

2ndLine can be downloaded for free. However, you do have to pay to remove ads and access additional calling features. 

Here are their paid options through an in-app purchase:

• International calling credits: $5 per bundle
• 2ndLine Premium, removes ads permanently: $9.99 per month + tax
• Call forwarding: Requires 2ndLine Premium, $9.99 per month + tax
• Lock in your phone number, prevents losing your number to inactivity: Requires 2ndLine Premium at $9.99 per month + tax

Since 2ndLine doesn’t have an up-front pricing page, you won’t know what you have to pay before downloading the app. You have to download the app, create an account, and verify your information before buying upgrades.

11. TextFree

Pros

• Local phone number

Cons

• Can get deactivated if you don’t use your number at least once in a 30-day period
• Requires upgrades or ‘earning’ free minutes to make phone calls
• Ads are present in the calling interface until you upgrade
• Can’t get more than one phone number per account

TextFree is a second phone number app for Android designed by Pinger, the company behind Sideline. You can select a phone number from a list of available area codes. Then start sending texts at any time.

What makes TextFree ‘free’ is its use of in-app ads. Many users say the ads are borderline intolerable and difficult to work around when trying to place calls. Plus, calling minutes are only free to earn, not free to use. You can purchase calling minutes outright for an undisclosed amount or earn credits by watching videos, downloading apps, or performing sponsored tasks. For example, a sponsored task could involve getting a prepaid Visa card. 

If you want to make calls without ads or earned minutes, you can upgrade to a TextFree Plus Subscription at $9.99 per month. However, this doesn’t provide any additional calling features, like recording calls on your Android device or using auto-attendants.

Like 2ndLine, TextFree requires you to constantly use your number or risk losing it. You have to make at least one phone call or text message in a 30-day period to prevent your number from being recycled. Otherwise, you can upgrade to the TextFree Plus Subscription to keep your phone number.

TextFree key features

• Local phone number
• Unlimited free texting
• WiFi calling
• Custom voicemail greetings
• Call blocking

TextFree pricing

TextFree only has one price plan for Android users:

• TextFree Plus Subscription: $9.99 per month to remove ads, get unlimited minutes, and permanently prevent the recycling of your number

Second number Android apps vs eSIM: Which is better?

Not sure whether to go with a virtual phone app or an eSIM for your second phone number? Here’s a quick comparison table to help you decide:

Feature	Second number Android apps	eSIM
Setup time	Five minutes	Can take hours if you need an eSIM-compatible device
Cost	$15–$50 per month for unlimited calls and texts	$25–$50+ per month for unlimited calls, texts, and data
Share calls and texts with a team	✅	❌
Works on multiple devices simultaneously	✅	❌, limited to a single device at a time
Automatic call recording	✅	❌
AI call summaries and transcriptions	✅	❌, requires a separate app

Most Android phones sold in the past few years come with a dual SIM slot. Android manufacturers have also made it easy to add eSIMs to your phone if you need them. In terms of pricing, you pay for an additional SIM just like your regular phone number. They’re great for personal use because you can switch between multiple numbers as needed. 

eSIMs fall short for business use. You can’t easily share that number with colleagues. You also can’t set up call routing flows, an IVR, or custom ring options. Plus, virtual phone providers make it easy to set up and use their platforms.

5 features to seek out with a second phone number app for Android

Feeling overwhelmed by all your options? We can help you narrow down the list.

Here are five critical features to consider before downloading a second number app:

1. Ability to tell when incoming calls are meant for your second number 

A second phone number should help you maintain a strong boundary between personal life and work. You should be able to see whether someone is calling your work or your personal number. 

If you have multiple numbers in your Quo workspace, you can see the emoji associated with a specific number so you always know how to respond. Plus, you can set business hours that send after-hours calls straight to voicemail.

2. Flexible call recording options 

Need the ability to record phone calls for both legal and practical purposes? Great second phone number apps let you record specific calls or automatically record all calls depending on what you want.

With Quo, you can use on-demand call recording at any time during a call. And for Business plan users, you can have automatic call recording for any numbers on your account.

3. Shared numbers

Shared numbers help everyone on your team make calls, send texts, and manage customer expectations together. You all have access to the same contact list and can even message internally when you need to delegate tasks.

Handle incoming calls together so you never miss an incoming lead. Every customer interaction is logged in a shared inbox, so teammates can easily catch up on what they missed. 

If you manage a team, you can easily jump into that inbox with Quo to see who on your team has been in touch with specific contacts. Plus, easily listen back to call recordings or review your full conversation history to coach your team.  

4. Calls, texts, and voice messages in a single view 

Everyone on your team should be able to review and follow up on past conversations with customers. The best second phone number apps keep all calls, texts, and voice messages in a single view instead of having to jump between separate folders.

Being able to see all the conversation history like this in Quo is available on every plan. They’re easily searchable, too. Just use the in-app search bar to hunt down texts or voicemails and get the context you’re looking for.

5. Setting availability

You can’t be around to pick up the phone all day — and frankly, you shouldn’t have to be. Your second phone number app for Android should set expectations about your team’s availabilityYou can do this in three different ways: 

• Setting permanent business hours for your entire number
• Temporarily turning off notifications with do not disturb
• Setting up auto-replies to send a text when someone attempts to dial you when you’re not able to take their call

In Quo, your teammates can even set specific shifts in which they’re available to take calls from any number they have access to. 

Ready to get your second number Android app?

A second phone number app can help you manage your business without compromising your personal number. That way, your number stays private. If you need a second phone number for yourself and you can live with ads, then a free app will do the job. If you need a second phone number to handle verification codes, an eSIM or additional carrier number can handle it. 

But if you need a second number you can share with your team, then VoIP apps are the way to go. VoIP systems like Quo give you everything you need to build better relationships with customers. Plus, you don’t need to blur the lines between your personal life and professional career.

See for yourself why thousands of businesses chose Quo as the best phone system for growing teams. Try us today with a seven-day free trial.
