Here’s a breakdown of our evaluation criteria:

RingCentral: Best Overall Android VoIP App for Small Businesses

RingCentral’s VoIP Android app lives up to their reputation as one of today’s leading VoIP providers. The platform manages to incorporate almost all the functionality of the desktop version into their mobile app, giving users call management, team messaging, unlimited calling, and text messaging functionality.

While RingCentral isn’t the cheapest VoIP app for Android devices, it delivers the most bang for your buck. You’ll unlock new features and integrations as you upgrade to higher RingCentral tiers, but every package (including their entry-level Essentials plan) includes their mobile VoIP app, unlimited calling, and unlimited text messaging (SMS).

While $19.99 per user, per month for Essentials isn’t too hefty a price, the app could be overkill for small businesses with less extensive needs. If your business needs a more affordable and simplified Android app, you’ll be better off choosing Google Voice.

RingCentral Features

• Connect RingCentral to a large variety and number of business apps with a suite of more than 200 third-party integrations and RingCentral’s developer API
• Manage calls and train your agents using call management features like whisper, barge, and take over
• Add video meetings to your mobile or desktop communication repertoire with RingCentral’s video conferencing functionality
• Configure your phone system’s settings, voicemail, notifications, and more on the go
• Enjoy advanced features like multilevel auto-attendants, hot desking, custom ringtones, vanity numbers, and real-time analytics

Nextiva: Easiest to Use Android App for Team Messaging

Nextiva provides one of the easiest-to-use VoIP apps for Android devices, with features and functionality bundled into a modern user interface. The team messaging functionality is one of its best features, giving users the ability to instant message co-workers in a single click and even screen share from their mobile device.

At $21.95 per user, per month, Nextiva is on the more expensive spectrum for VoIP apps, but it delivers an exceptional communication experience for agents and customers alike. Unfortunately, users on the entry-level plan don’t get access since Nextiva locks the mobile app behind the Professional tier.

If having high-end features and extensive third-party integration capabilities aren’t top factors when it comes to your business’ phone system, then consider a simpler platform like Google Voice. The Google Voice app still has powerful features and functionality, but with a more affordable pricing plan.

Learn everything you need to know about Nextiva in our expert Nextiva review.

Nextiva Features

• Learn everything there is to know about your caller before you pick up the phone with caller insights provided by Nextiva’s Call Pop feature
• Host video conferencing meetings for up to 250 participants starting on the Professional tier
• Switch between your desktop and mobile app quickly—even in the middle of a call
• Start an instant message chat with co-workers in seconds and even screen share from your mobile device
• View, listen, and manage your voicemails from the mobile VoIP app or your email inbox

Bria Mobile: Best Android App for Supplementing Existing Phone Plans

Unlike the other providers on this list, Bria Mobile isn’t a virtual phone service or a business phone system. Bria Mobile is an Android and iOS app you can use to add extra functionality to your existing phone service. Additional features include custom ringtones, caller ID, and real-time network quality indicators.

While Bria Mobile has reasonably low prices, you’ll need to add in the expense of your existing phone service to calculate your total cost. However, it’s beneficial for small businesses and solopreneurs that want robust mobile functionality but can’t afford the high prices of premium phone system calling plans.

On the downside, you’ll miss out on some basic features like auto-attendants, CRM integrations, and unlimited call recording. If you want a simple VoIP app to install on your personal device, Bria Mobile is a good choice. However, if you need an all-in-one VoIP business phone system, you’ll want to look at RingCentral or Nextiva.

Bria Mobile Features

• Assign custom ringtones and images to your contacts to quickly recognize incoming callers
• Integrate contacts from various sources to streamline your communications and keep all your systems in sync
• Take advantage of Bria Solo Free to get a taste of what the app has to offer before entering your credit card number
• Watch real-time status indicators of your call quality to resolve issues before they become unmanageable

Google Voice: Best Android App for Google Workspace Users

Google adds VoIP functionality to Google Workspace with the simple, easy-to-use Google Voice app. It’s not the most robust VoIP solution out there, but it delivers on core features like calling, texting, video conferencing, and even a multilevel auto-attendant.

Google Voice’s user interface feels familiar and is easy to navigate. Plus, it integrates smoothly with other Google Workspace apps, like Gmail, Calendar, and Drive. At $10 per user, per month, it’s one of the cheaper entry-level options on this list.

However, Google Voice doesn’t offer the call management features and extensive integrations some of its competitors do. If you need those features, you’ll likely need to upgrade your mobile app using Bria Mobile or MizuDroid to get the additional functionality.

Check out our extensive Google Voice review to learn the ins and outs of the virtual phone service.

Google Voice Features

• Integrates easily with other Google Workspace apps like Calendar, Gmail, Google Fi, and Google Meet
• Video conference with teammates or customers using the Google Meet integration
• Build intelligent multilevel auto-attendants to route your callers to the right extension
• Enjoy unlimited users, domestic locations, and international locations when you upgrade to Google Voice’s Premier tier
• Switch between web and mobile applications quickly to work the way you need to

MizuDroid: Best Android App for Low-cost International Calls

Like Bria Mobile, you’ll need an existing SIP account with a phone service provider, but MizuDroid expands your mobile device’s encryption, voicemail, and call diversion capabilities. The user interface is a bit outdated, but it’s a free app (with no in-app purchases) that can expand your mobile VoIP possibilities.

With MizuDroid, international calling is a simplified process as long as you have a VoIP provider, a PBX, or a SIP server. Calls of this nature are also crystal-clear thanks to the software’s ability to automatically adapt the connection to the existing device, network, server, or peer capabilities. As a result, both receiving and making international calls is potentially more convenient and cheaper than other Android apps that support international calling, like RingCentral.

You’ll need to upgrade to the Pro Edition for a one-time payment of $49 to gain access to features like G.729 and auto-encryption. You can also contact the MizuDroid team for fully customized and white-labeled softphone apps for your business.

If you’re looking to expand your existing phone plan’s mobile functionality, MizuDroid is an excellent choice for your Android phone. However, if you’re looking for a unified communications platform to use on your mobile device, you’ll be better off with RingCentral or Nextiva.

MizuDroid Features

• Supports multiple SIP accounts, call encryption, voicemail, and instant messaging
• Customize your MizuDroid app for a white-label experience
• Manage multiple simultaneous calls on a single device
• Use for free with a personal account until you’re ready to upgrade for commercial use

Vonage: Best VoIP App for Advanced Messaging Features

Vonage isn’t the most feature-rich VoIP platform on this list, but its mobile app delivers some of the most advanced mobile messaging functionality. Plus, its mobile Android app is included on all pricing tiers.

Vonage’s mobile messaging isn’t an afterthought—it contains similar functionality to robust standalone messaging apps like Slack. However, Vonage drops the ball in a few key areas. It doesn’t provide annual pricing discounts or vanity numbers, and the user interface can be clunky and difficult to navigate at times.

At $19.99 per user, per month, it’s on the pricier end of business phone systems. For the same price, you can get more features and an improved user experience with a solution like RingCentral.

Vonage Features

• Enable better team communications with unlimited messaging on a powerful messaging app
• Purchase add-on features like toll-free numbers, Vonage Support PLUS, call recording, and visual voicemail
• Rest easy knowing your communications are ensured with 99.999% uptime reliability
• Take advantage of existing hardware by using compatible IP desk phones
• Customize greetings and check your voicemail messages from within the mobile app

Bottom Line

VoIP apps for Android devices put the most important features of your business phone system on your mobile phone. Features like video conferencing, SMS text messaging, vanity numbers, faxing, and voicemail all help you keep in touch with co-workers and customers, regardless of where you are. These apps also effectively separate your business phone number from your personal line.

We found RingCentral to provide the best VoIP app for Android devices. It delivers the right combination of features and functionality at a justifiable price range. If a business phone system is beyond your needs, you may be satisfied with a more basic phone system like Google Voice instead.
