7 best VoIP apps for iPhone

Now that you know what to look for with an iPhone VoIP solution, here are seven apps that can help you streamline your business communication. 

1. Quo (formerly OpenPhone): Best iPhone VoIP app for growing teams

Pros

• Intuitive and easy to use
• Add numbers for free as your business grows
• Store call recordings with additional context

Cons

• No guaranteed two-factor authentication texts*

*This is a limitation for all second phone number apps on iPhones.

Quo’s modern VoIP solution and Apple iOS go together like two peas in a pod. You can use all the native features of your iPhone with a number from Quo to avoid making business calls with your personal ID. Plus, you can get multiple phone numbers within US and Canadian area codes, along with toll-free phone numbers in North America.

If you need to use Quo with your team, no one is left in the dust. Quo has a downloadable VoIP app for Android, Mac, and PC. Plus, you can use the Quo web app to easily call and text from your browser. Have existing phone numbers linked with a less flexible VoIP app? Don’t sweat it — you can use Quo’s number porting feature to get all new features with your same number.

When you get a VoIP number from Quo, you can create shared phone numbers that allow teams to collaborate in real time. Shared numbers allow everyone to answer incoming calls on the device they’re using. Plus, teams can make VoIP phone calls simultaneously using the same number.

Quo’s VoIP solution is designed to grow alongside your team. Our lightweight CRM lets you add unlimited contacts and custom contact properties so you can more effectively build relationships with customers.

We also offer thousands of integrations that create dedicated workflows for automatic logging, voicemail forwarding, repeat text messages, and more. You can save time on your routine communication workflows in thousands of ways with Slack, HubSpot, Make, and Zapier. You can also tag calls to keep your inbox organized and help your team prioritize follow-ups. Quo’s API lets you trigger texts from other tools — for example, sending an appointment reminder when someone books through Calendly. And if you need help handling calls when your team is unavailable, Sona, our AI voice agent, can greet callers, collect info, and generate summaries for your team.

How to get a virtual internet phone number

You can obtain a virtual phone number with Quo in three simple steps:

1. Sign up for an account with OpenPhone — when you sign up, you can try out Quo free for seven days.
2. During signup, select your city or area code in the US or Canada to pick your phone number or select a North American toll-free number.
3. Verify your account with an existing phone number and a credit card.

During the signup process, you’ll be asked for a credit card to help keep bad actors off the platform, but you can try calling from your computer for free to confirm it’s a great fit. And when your trial is set to expire, we’ll even email you a heads-up to the email address you used to sign up.

If you run into any issues during the signup process, fill out this form to reach our support team.

2. Google Voice: Best budget iPhone VoIP app for Google Workspace users

Pros

• Calls sync across multiple devices mobile devices
• Can share responsibility for incoming calls on paid plans

Cons

• No toll-free numbers
• Calls, texts, and voicemails live in separate folders
• No ability to collaborate from a shared inbox

Google Voice is another well-known mobile VoIP service. Their legacy-free VoIP system expands the calling capabilities and features of the iPhone and can synchronize across multiple devices (think your laptop or tablet).

However, Google Voice can be problematic for businesses with multiple members. Only one number is available per account. Plus, no shared numbers are available if your team needs to work together to build relationships with customers over the phone. Even if you’re a solopreneur, being limited to just one phone number could cost you business in the future.

While Google Voice for personal use is free, Google Voice for Google Workspace (the business plan) does cost money. It’s $10 per user per month to access the basic plan and $7 per month to access Google Workspace. That’s a minimum of $17 per user per month — just for the lowest tier plan.

Once you sign up, you may run into other major issues, such as Google Voice not offering auto-replies or toll-free numbers. Calls, voicemails, and text messages live in separate folders in Google Voice’s mobile app, making it far more time-consuming to catch up on conversations. It’s easy to see why Google Voice isn’t the best VoIP app for iPhones on our list.

Key features of Google Voice

• Free voice calls to Canada from the US
• Unlimited SMS in the US
• Voicemail transcription
• Google Meet and Google Calendar integrations
• Ring groups (upgrade required)

Google Voice pricing

Google Voice’s pricing plans give you three different options to pick from:

• Starter: $10 per user per month for call forwarding, voicemail transcriptions, and text messaging in the US only (up to 10 users max)
• Standard: $20 per user per month for on-demand call recording, desk phone and ATA support, and ring groups
• Premier: $30 per user per month for automatic call recording and advanced reporting through BigQuery

3. Nextiva: Best for enterprise brands

Pros

• Team chat
• Mobile app for voice and SMS

Cons

• Texting is limited to 100 texts per user per month
• Call recording requires a paid add-on
• Limited toll-free minutes

Nextiva offers unlimited calling in the US and Canada, making it a solid choice for users looking for a reliable iPhone VoIP app. Its starter plan includes unlimited calls to the US and Canada, which is helpful if you want to contact customers from your iPhone without extra costs.

It’s worth noting that Nextiva’s base plan only lets you send 100 SMS messages per user per month. You also won’t be able to text as a team unless you upgrade to the Engage plan, which costs $25 per user per month. Plus, if you want access to unlimited texts, you’ll have to upgrade to the Power Suite plan ($50 per user per month). 

If texting images to customers or allowing them to call you in a cost-effective way is a priority, a Nextiva alternative may be a better choice for your business.

Key features of Nextiva

• MS Teams integration (requires upgrade)
• Local or toll-free numbers
• Digital fax (requires paid add-on)
• Integrations with Outlook and Google Contacts
• Video conference calls (up to 45 minutes)

Nextiva pricing

Nextiva’s pricing offers three different plans to choose from:

• Core: $15 per user per month for inbound and outbound voice, video meetings, call routing, screenshare, and file share
• Engage: $25 per user per month for customer-to-team SMS messaging, toll-free number and minutes, and advanced reporting
• Power Suite: $50 per user per month for inbound sales and service call center, priority and skills-based routing, and unified team interface

Rated 4 out of 5 stars from 5,800+ reviews

4. RingCentral: Best VoIP app for iPhone with legacy phone features

Pros

• Unlimited calling in the US and Canada
• Microsoft integrations

Cons

• Desk phones are only available with multi-year contracts
• Texting is limited to 25 texts per user per month
• Toll-free minutes are limited to 100 minutes per month

With RingCentral, you can manage calls, texts, video meetings, and team chats directly from your iPhone. It’s easy to set up and use, and each plan includes a free business or toll-free number. If you work from an office, you can also set up internet fax and desk phones.

If you’re looking for a one-stop shop, RingCentral may fall short when choosing the best VoIP app for your iPhone. If you want third-party integrations, automatic call recording, or analytics, you’ll have to upgrade to the second-tier plan — $25 per user per month. Texting comes with limitations as well. You can only send up to 25 texts per user per month on their base plan and store 5,000 texts per user.

Key features of RingCentral

• Voicemail-to-text
• Desk phone rentals
• Team messaging (limited storage)
• File sharing (limited storage)
• Unlimited calling in the US and Canada

RingCentral pricing

RingCentral’s pricing plans give three different options:

• Ultra: $35 per user per month to access video conferencing (200 participants), device analytics, and unlimited storage

Rated 4.8 out of 5 stars from 64,800+ reviews

5. Zoiper Softphone Premium: Best for personal use

Pros

• Runs in the background without draining your battery
• Bluetooth pairing for hands-free calls

Cons

• Free version contains ads
• Doesn’t come with an AI voice agent
• Requires a separate PBX or SIP provider

Zoiper is a softphone app that works by using Session Initiation Protocol (SIP) technology. SIP lets you use the internet to call and text customers with your existing PBX system (the hardware that connects all your company’s desk phones). That means you can use it to make VoIP calls without needing to buy new hardware.

Zoiper supports a handful of features that make it easier to manage calls. You can transfer live calls, enable call waiting, or record conversations for future reference. It also supports conference calling — so you can hop on group calls without needing another app.

You can also pair it with your Bluetooth headset to take calls hands-free. That makes it a helpful tool for staying connected when you’re on the go. 

But Zoiper comes with many drawbacks that stop it from being the best VoIP app for iPhones. It doesn’t support customer texting or offer an AI voice agent to automatically handle calls for you. And while there’s a free version, it comes with limited ‌features along with ads, which can interrupt your workflow and seem unprofessional to your employees.

Key features of Zoiper Softphone Premium

• Video calls (requires upgrade)
• Call waiting (requires upgrade)
• Call recording (requires upgrade)
• Call transfer (requires upgrade)
• Conference calling (requires upgrade)

Zoiper Softphone Premium pricing

Zoiper offers a one-time payment model for desktop and mobile apps — no monthly subscription required. If you’re using the mobile app, extra features are available as in-app purchases. These range from $1.49 to $12.99 each, depending on what you want to unlock.

The desktop version, Zoiper PRO, costs $49.95 for lifetime access. That gives you unlimited use without ongoing fees.

Rated 3.5 out of 5 stars from 130+ reviews.

6. Groundwire: Best for white labeling 

Pros

• White-label branding (requires a one-time $4,200 fee and $549 monthly payment)
• Battery-saving push notifications

Cons

• No built-in calling or texting
• ZRTP-encrypted calling costs an additional $24.99
• No AI agent

Groundwire is a VoIP SIP softphone that works with your existing private branch exchange (PBX) system. That means your team can make and receive calls and texts using the office setup you already have — no need to switch services.

The app includes instant messaging, so you can quickly connect with teammates. You get voicemail, too, so you never miss a message. Plus, you’ll have access to group calls and call transfers to help your team stay in sync and solve customer issues faster.

If you want to launch your own VoIP app, Groundwire offers a white-label option. Your app can appear in the Apple App Store and Google Play Store under your company’s name, not Groundwire’s. Pricing starts at a one-time fee of $4,200, plus $549 per month for updates and support.

But Groundwire isn’t a full phone system. It doesn’t include its own calling or messaging service. You’ll need to connect it to a separate VoIP provider, which can make setup more complicated and expensive. And if you need ZRTP-encrypted calling for extra security, you’ll have to upgrade. You’ll also need to download and pay for the app to find out how much it costs.

Key features of Groundwire

• HD video calls
• Multi-device support
• Call transfers
• Voicemail
• Group calls

Groundwire pricing

Groundwire is a paid app with a one-time download fee of $9.99. You can unlock additional features through in-app purchases, which range from $1.29 to $32.99 per item.

If you’re interested in the white-label option, pricing starts at a one-time fee of $4,200, plus $549 per month for support, maintenance, and updates.

Rated 3.8 out of 5 stars from 92+ reviews.

7. Bria Mobile: Best for multiple SIP accounts on one iPhone

Pros

• Speaker, mute, and hold functions
• Call recording

Cons

• Setup may require technical expertise
• Requires a separate SIP-compatible VoIP or PBX provider
• Users report reliability issues

Bria Mobile is a SIP softphone that connects with your existing VoIP provider. That means it doesn’t include its own calling service — it simply gives you a way to make and receive calls on your iPhone from a provider you already use.

If you rely on more than one VoIP service, Bria can help you manage everything in one place. It supports multiple SIP accounts, so you don’t need to juggle different apps to keep up with customer communication.

You can also take calls in the background while using other apps. That way, you can keep working without having to stop everything just to answer the phone.

Keep in mind Bria costs $0.99 per user per month, which you’ll need to pay for along with your VoIP service. That might not seem like much, but it can add up quickly as your team grows. One user also noted “Occasional complexity in setting up advanced features and potential need for technical expertise.”

Key features of Bria Mobile

• HD voice and video calls
• iOS and Android apps
• Push notifications
• Call history
• Call recording

Bria Mobile pricing

Bria Mobile costs $0.99 per user per month. Your subscription starts with a 14-day free trial, so you can test it out before committing.

How we ranked the best VoIP apps for iPhone

We tested multiple second phone number apps to determine which platforms stood out. After trialing the software, we used reviews from G2 and TrustRadius to back up our research with others’ experiences. 

We compiled this information to make an informed decision. Then, we ranked our top seven best VoIP apps for iPhone based on six criteria:

1. Pricing: Money isn’t everything, but the price you pay for a VoIP could have a significant impact on your bottom line. We chose competitive virtual phone number providers with the most cost-effective prices for plans.
2. Interface: We trialed each provider and then selected intuitive platforms that were easy to navigate and understand. That way, you can get a second phone number with as little hassle as possible.
3. Features: We looked for VoIP apps that come with modern features that make communication a breeze, including additional features that grow alongside your brand, such as call routing, automation, and AI.
4. Reach: We looked for VoIP apps that reach contacts all over the world. Whether you’re in the US or want to connect with customers overseas, you should have that option with your provider.
5. Integrations: Modern business phone numbers should connect your favorite platforms and automate unnecessary tasks. For this reason, we picked VoIP solutions with one or more third-party integrations.

How to make calls from an iPhone

If you’re still not sold on using a VoIP app, you can always make calls from your iPhone. Let’s explore these options below:

1. Use a regular SIM: The standard SIM card provided by your network carrier lets you make calls using your provider’s network, typically through a plan that includes voice calling minutes. A regular SIM ties you to one number, and international plans can get pricey.
2. Use an eSIM: If your iPhone supports eSIM technology, you can opt for an embedded SIM card. eSIMs offer the convenience of cell service but let you call without a SIM card. You can switch between phone numbers and carriers using an eSIM — but you’ll need an eSIM-compatible device and may need to activate it before traveling.
3. Use a cloud-based VoIP: A VoIP service provider allows you to make calls over the internet and bypass traditional phone providers. You likely already use (or have heard about) VoIP apps such as WhatsApp to call and text numbers from anywhere in the world.

A VoIP provider such as Quo takes this technology a step further by integrating business features such as shared phone numbers, business hours, and texting automation.

5 benefits of using a VoIP app for iPhone

Let’s dive deeper into the benefits of a VoIP app built for business use.

1. Work from anywhere: VoIP apps enable you to stay connected regardless of your location, allowing you to make and receive calls over WiFi or cell data. Whether you’re in the office, at home, or traveling, you can maintain communication without having to set up call forwarding.
2. Cut costs: VoIP providers often offer low-cost rates for domestic and international calls and texts compared to traditional phone services. Plus, you get access to features cell carriers don’t typically provide, such as call transferring and ring groups to help manage calls.
3. Manage calls as a team: A VoIP app allows you to easily transfer calls between colleagues, set up call groups, and collaborate on calls using internal notes. These features help you provide better customer service.
4. Integrate your phone system with other tools: Most VoIP apps integrate with popular business tools such as CRM software, email platforms, and project management tools. This helps you streamline workflows by accessing relevant information and tools directly from your communication platform.
5. Save time with automation: Tools such as auto-replies to text messages, templated messages, and call recording help your team save time. This frees them up to focus on providing a superior experience for your customers. 

6 things to consider when selecting a VoIP app for iPhone

Whether you’re a lean startup or an established business, you’ll want to select a VoIP app that makes daily communications a snap.

Here are six factors you should consider when choosing a VoIP app for your iPhone:

1. Do you need a local or toll-free number?

The type of business phone number you choose will set underlying expectations for clients. For example, a local number that starts with a familiar area code might encourage customers to pick up the phone. On the other hand, toll-free phone numbers aren’t tied to a specific region but let anyone in the US, Canada, and many other North American regions and countries call you for free. Plus, toll-free numbers can give your business a professional and high-profile appearance.

If you can’t seem to pick between the two, you can always get both with the right provider. 

2. What integrations do they offer? 

One of the best things about VoIP is its ability to connect with thousands of other platforms. From CRMs to accounting software, you can create workflows that save dozens of hours, hundreds of dollars, and countless headaches. 

VoIP systems without integrations are no different from traditional carriers. 

3. How intuitive is the app?

A confusing VoIP app could damage your business. Spending too much time on dashboards that aren’t user-friendly could throw curveballs into your team’s workflow, costing you customers and time.

To avoid this, you’ll want to choose a modern app that works as easily as the default calling on your cell phone. An easier adoption process means you won’t spend all your time training the team — or waiting to hear back from your business phone provider’s customer support.

4. How can you access the app? 

You’re not always going to be somewhere with a landline — but you’ll still need to make calls. Be sure your VoIP app can run on the devices you use every day, including smartphones, laptops, and smartwatches.

The best VoIP apps (like Quo) let you make free calls and texts as long as your iPhone has a stable internet connection. If you need to step away from your desk but are still on a call, you can switch to your data plan to keep the conversation going. And if you ever wanted to access your number from something other than your iPhone, you can click-to-call on your Mac to reach contacts in seconds. How’s that for accessibility?

5. What features do they offer that can save you time? 

The VoIP app you choose should be filled with tools that make your life easier.

A few key features to keep in mind include:

• Voicemail-to-text: Features like voicemail transcription can be a lifesaver, especially while on the go. Quickly skim through translated text without having to download an audio file or call a voicemail inbox.
• Auto-attendants: By using a phone menu that greets callers and gives them options to reach different departments, you can automatically route them to the right information and teammates. Plus, you can deliver the phone presence of a large company — even if it’s just you.
• Call analytics: How many calls are you getting? How long do they last? Analytics should solve all this and more.

6. How scalable is their offering?

Your business is going to grow — it’s just a matter of when. And if you don’t have the right VoIP app in place, meeting greater demands can feel impossible. What if your plan only allows a certain number of users? Can you get additional numbers or create shared numbers for teams? In a nutshell, you should choose a VoIP solution that grows as your business grows. 

The best VoIP app for iPhone: Quo 

If you heavily rely on your iPhone to manage your business communications, Quo may be the best VoIP app for your business. Quo offers plenty of automation features and integrations to take repetitive work off your plate, letting you provide top-notch customer service directly from your cell phone. 

Plus, with the convenience of receiving business VoIP calls to any of your iOS devices (Mac, iPad, or iPhone), you won’t have to worry about missing important calls or texts when your iPhone is charging.
