This article is part of a larger series on VoIP.
If you have an iPhone and want to make calls over the internet or Wi-Fi, a voice-over-internet-protocol (VoIP) app is essential. iPhone users have many options, from pricier cloud-based business phone systems to iOS VoIP apps from virtual phone number providers that give you a second phone number and keep your personal and business calls separate.

Bria: Best Overall VoIP App for iPhone Users
*Annual prepayment required for all plans, except Bria Solo Free.
Bria’s mobile app, also referred to as CounterPath Bria, earns the top spot as the best VoIP app for iPhone. With any paid plan, the Bria app becomes a unified communications (UC) platform that integrates with your existing VoIP service, call server, or internet protocol (IP) public branch exchange (PBX) system. It’s ideal if you want to keep your current phone service but need a better mobile app with Siri functionality.
With that said, Bria’s SIP-based tools won’t work as a standalone VoIP business phone system, and only the Enterprise plan (pricing requires a quote) offers SMS text capabilities. For unlimited calling plans, consider the iPhone app from Vonage Business Communications (VBC). Its highly rated iOS app is also an all-in-one UC solution with texting, video, and voice that works with Siri and includes VoIP service.
The newest version of the Bria mobile app rolled out in 2021, earning a solid 4.5 out of 5 with 531 customer reviews in the Apple App Store. The previous version scored nearly as high—4.4 with 2,022 ratings. The app features high-definition (HD) video and audio, call recording, and click-to-dial with paid subscriptions. It also syncs to your Apple Mac address book, and the Teams version supports up to four devices.
CounterPath Bria Features
- VoIP and PBX interoperability: Bria connects to many phone systems, including Avaya, OnSip, Mitel, and Cisco, and you can view up to five accounts from one VoIP iPhone app. It’s also compatible with desktops, headsets, and internet protocol (IP) phones so that you can use it in and out of the office.
- Remote teamwork: Empower your employees to solve issues remotely with mobile screen sharing, video conferencing, and live chat tools. With persistent chat rooms and presence status, each team member can see who’s available and reach out with a question.
- Contact list sync: Pull data from your Mac address book or use the lightweight directory access protocol (LDAP) and active directory to import contacts from your customer relationship management (CRM) solution.
Pinger: Best VoIP iPhone App for International Texting
*Pricing is based on a monthly payment, but six-month ($39.99) and one-year ($69.99) subscriptions cost less.
Pinger is a free VoIP app for iPhones that provides a local phone number. Unlike Vonage that only offers texting for U.S. customers, or Line2, which charges for international messages, Pinger lets you receive text messages from customers worldwide and send them to clients in 36 countries.
The Pinger Plus plan supports unlimited calling to the U.S., Canada, and Mexico and costs less than other unmetered apps, including Line2 and Vonage. It syncs your address book contacts to your VoIP app and allows you to edit contacts from your iPhone. Other features include voicemail, separate ringtones for your Pinger number, and group chat. However, it lacks the scalability of Vonage, charges per-minute fees for calling Alaska, and doesn’t support business hours like Google Voice.
Pinger’s iPhone app gets 4.6 out of 5 with more than 17,200 ratings in the Apple App Store. Plus, you can earn minutes by watching video ads on the ad-supported free version, making Pinger a good free iOS VoIP app for inbound and outbound business calls.
- Auto-reply: Create and save up to three 160-character text messages that Pinger sends automatically to missed callers when enabled. Pinger only sends the message once, even if customers call you more than once during a 24-hour period.
- Three-way conferencing: Although Pinger lacks the larger conference capacity of Vonage (30 attendees) and Line2 (99 participants), you can add a third person to the line.
- Voicemail: Record up to three voicemail greetings and automatically transcribe voicemails using the standard Pinger iOS VoIP app. You can also search your inbox for keywords, such as a term like “appointment” or a project name.
Vonage Business Communications: Best iPhone VoIP App for Scaling With Your Company
*Prices are based on one user. Volume-based discounts apply for five or more users.
Vonage Business Communications stands out for its flexible VoIP products and integrations that ensure your phone system can handle your business growth. As your company expands, you can connect teams using desk phones, create custom solutions with application program interfaces (APIs), and support your call center with contact center software.
The Vonage Mobile plan is perfect for iPhone users, giving you access to over 50 features including file sharing, contact editing, team messaging, and video meetings. Higher-plan tiers provide a multi-level auto-attendant, call recording, and native CRM integrations, including Salesforce, an option otherwise only available to Bria Enterprise users.
Plus, the iOS VoIP app—which has a 4.7 out of 5 rating with more than 10,500 ratings in the App Store—works with Siri, so you can use your voice to make calls while on the go. However, Vonage is the most expensive VoIP app and doesn’t offer a free version. Google Voice is a more affordable alternative, as solopreneurs can use the free version, and as your company grows, its paid packages cost almost $10 less per month than Vonage plans.
Vonage Business Communications Features
- Integrations: Vonage connects to the largest number of third-party tools. The entry-tier plan includes over 20 integrations from the Vonage App Center, including Slack, Zapier, and Microsoft Teams. Premium and Advanced versions work with several CRMs, such as Zoho CRM, HubSpot, and Salesforce.
- Call flip: Assign up to five devices to your phone number or extension and use them simultaneously to seamlessly switch devices between calls. This is great for mobile users who want to walk in the door and share a computer file from their desktop without hanging up and starting the call over.
- Collaboration: Like Bria, Vonage connects teams working remotely. Along with text messaging, your staff can use team messaging to share files or jump on a video or conference call. However, the audio conference bridge supports up to 30 attendees, whereas Line2 offers a unique “merge” feature that lets you add up to 99 participants.
Google Voice: Best Free iOS VoIP App for Solopreneurs
*Paid Google Voice plans require a Google Workspace subscription, starting at $6 per user, per month.
Google Voice is an excellent solution for solopreneurs wanting unlimited VoIP calling and a business phone number for free. It differs from the free Pinger app because Google Voice doesn’t use an ad-based model or charge for domestic minutes.
The free version includes voicemail transcripts, and you can screen calls by listening to voicemail in real time and picking up the call or letting the caller continue to leave their voicemail. Like Pinger, you can search messages, but Google Voice doesn’t support international texting. And your iPhone VoIP app only supports one business phone number compared to five with Line2.
The free version also supports up to 10 people on a conference call (or 25 with paid plans) compared to just three with Pinger. Plus, you can simultaneously ring up to six devices. While not as scalable as Vonage and lacking integrations with CRMs, the Google Voice iPhone VoIP app scores 4.3 out of 5 with 38,800 ratings in the App Store and is extremely easy to use.
If you outgrow the free version, paid plans offer more features than Line2 or Pinger, yet cost less (even with the required Google Workspace subscription, starting at $6 per user, per month) than Vonage. Plus, Google Voice business numbers are portable, so that you can transfer your current number to a new VoIP system.
Google Voice Features
- eDiscovery: Easily find communications from a customer or locate messages regarding a topic using the eDiscovery tool. It turns your calls, text messages, and voicemail into searchable content, allowing you to quickly find the information you need.
- Call recording: Google Voice is the only free iOS VoIP app with call recording. You can enable this feature under your Settings tab and tap the number four to start or end recording. The system automatically tells the caller that the call is being recorded. The recordings are stored with your voicemails and transcribed so that you can review conversations later.
- Ring groups: The Standard versions include a multi-level auto-attendant and ring groups, which let you route calls to a group of employees, such as your sales team. Line2 and Pinger don’t support ring groups, and Vonage charges $4.99 per month, per call group. Learn about other free and paid features in our Google Voice review.
Line2: Best iOS VoIP App for Users With Limited iPhone Storage
*Pricing is based on monthly payments. Select annual billing for additional savings.
Line2 is an excellent option for business users whose devices don’t have a lot of storage. The iOS VoIP app takes up only 71.2MB of space, compared to Google Voice (138.2MB), Pinger (107.2MB), and Vonage Business Communications (186.6MB).
Bria comes close at 83.1MB but only works with an existing call server or VoIP service. Although Line2 takes up less space, it doesn’t sacrifice user experience, as it earns 4.3 out of 5 in the App Store with over 9,500 ratings.
In addition, a virtual receptionist comes with the Starter plan, which costs less than Google Voice Standard ($20) or Vonage Premium ($29.99). You can also manage calls on up to five business phone lines, compared to one with Google Voice. Line2 is also the only iPhone app offering a free, professionally recorded greeting when ordered within seven days of opening your account.
Although you can text any Canadian or U.S. number for free, Line2 charges 10 cents per international text. In addition, Line2 only lets you change your phone number once within 30 days, and additional changes incur an activation fee of $20. If you have a global customer base or want new numbers frequently, consider Pinger, as it comes with unlimited texting to numbers in 36 countries, and you can update your number often.
- Toll-free numbers and minutes: Line2 and Vonage are the only apps offering an 800-number with your subscription. However, Line2 comes with unlimited toll-free minutes, which can deliver incredible cost savings with higher call volumes. In contrast, Vonage charges $2.99 for 100 minutes.
- Greetings library: Create greetings for voicemails, departments, and after-hours and save them in a central location. Plus, take advantage of a free professional recording from a Line2 voice actor for your auto-attendant.
- Call merging: Line2 lets you add up to 99 people to a phone call, making it a great option for companywide calls. In comparison, Pinger only offers three-way calling, and a paid Google Voice subscription supports just 25 people.
