Android VoIP apps can get you an alternative phone service on your mobile for little to no money.
A VoIP app allows you to make calls from your mobile phone. You only pay for data usage over 3G/4G. Your mobile phone provider may charge you for a local call.
Currently, Android holds the majority of the smartphone market. Part of the platform's dominance has to do with the wide variety of phones and its availability between the major mobile providers. On the other hand, Android smartphones are sold by every major provider (AT&T, Verizon, Sprint, and T-Mobile) and many different manufacturers.
It’s clear that we aren’t as dependent on mobile networks as we used to be. You can receive a data signal in the same places you can receive a mobile signal. People are starting to use Wi-Fi more often as well. Technological advancements have given us the ability to talk to someone over the Internet the same way we would talk to a person over the phone. If you’re ready to ditch your mobile network for something that’s not only easier to use, but also cheaper and more efficient, here’s a list of some of the best apps you can use for SIP and VoIP calls.
Here's a list of the top 10 best Android apps that let you make free VoIP calls:
1. WhatsApp
Cost: Free
WhatsApp is very popular for messaging, but something you may not have noticed is that it will support video and voice calls. The platform is rock solid and extremely popular, which makes it easier for other people to download the app so they can call each other. It includes extra goodies such as address book integration, multimedia support, and file attachments. If you’re someone who needs an actual phone number, this app might not be the best option. If you’re not, this app is great and should work fine otherwise.
2. Facebook Messenger
Cost: Free
An above average application, Facebook messenger includes support for SMS messages, voice calls, and video calls. While it does work best for text messages, the quality of the app is based on how fast your Internet connection is. The app also heavily relies on resource usage, which is why it’s not recommended on lower or older devices.
Another option you can try is Messenger Lite which is less reliant on system usage, although it only texts and calls. You can’t really go wrong with either option you choose.
3. Google Duo
Cost: Free
One of the latest video calling applications is Google Duo. It also supports regular voice calls quite well. In order for the calls to work, though, everyone needs to be on Duo. The video and voice quality are excellent and it’s very simple to use. Even better is the cost, which is free! All you need to do is make sure that your friends sign up for the app. Then you are ready to use it. It works with iOS devices and comes pre-installed on some new Android devices.
4. magicApp
Cost: $9.99 per year, some parts are free.
One of the more popular SIP/VoIP apps around is magicApp. It uses a person’s actual phone number to make calls. The app includes SMS support, landline support, and cross-platform support. The downside is that this app is not free. It costs $9.99 per year. You will receive unlimited calls to the United States and Canada, unlimited texting to any phone number in the United States, and a real phone number to use. It works well with your PC or mobile device.
5. Google Hangouts
Cost: Free
One of the better VoIP applications is Google Hangouts because it works similarly to Facebook Messenger. While most people use it for sending pictures or texting, it does support group calls, voice calls, and video calls too. You can even connect your Google Voice number for phone calls, voicemail, and SMS texting. If you’re only looking to make video or voice calls, Google Duo is better for that. Google Hangouts is for someone who wants a little bit of everything. It’s free to download in the app store without any advertising or in-app purchases.
6. MizuDroid SIP VoIP Softphone
Cost: Free
One of the few SIP applications that is updated regularly on Google Play is MizuDroid. You must have an existing SIP account to use it, but it supports numerous SIP accounts, VoIP tunneling, call diversion, IM, voicemail functionalities, and encryption. The UI featured in this app is a little older, but it’s still simple to use and functional. There are no in-app purchases as this app is completely free.
7. Skype
Cost: Free
One of the most popular VoIP apps in existence is Skype. With direct support for both Facebook and Microsoft and a massive user base, it’s very easy to use. You can use this app to send text messages and to send video and voice calls. For a small fee, you can also make landline calls. While the desktop application seems to work better than the mobile application, it’s not terrible. Skype has cross-platform support for many mobile and PC devices. And it’s free. There’s not that much wrong with it. Otherwise, not many people would be using it.
8. Signal Private Messenger
Cost: Free
If you’re looking for a VoIP app that includes privacy features, Signal Private Messenger is a good app to try. It supports voice calls and texting but doesn’t have a notable list of features. It does feature above-average privacy, encryption, and security capabilities, and integrates with your existing contact list and phone number. That was something we really liked. Telegram is best for texting, and Signal is best for voice and other extras. There are no in-app purchases and it’s completely free.
9. Viber
Cost: Free (with the purchase of extras inside the app)
Viber isn’t as popular in the United States as it is in the rest of the world, but it does feature a complete chat service, video calls, and voice call service. It also has options to include file attachments, public chats, and stickers. The stickers do cost a little extra, however. It’s a compact cross-platform VoIP and SIP option to choose from.
10. Zoiper IAX SIP VoIP Softphone
Cost: Free, or $8.49 with purchases inside of the app
Zoiper is one of the few SIP and VoIP applications left which is why it is so unique. It focuses mostly on phone calls and includes support for Bluetooth, IAX support, the ability to make phone calls over the Internet, and other additional protocols.
If you select their Gold package, you will receive better audio, call transferring capabilities, and video calling support. It’s one of the last good SIP applications out there. If you’re someone who mostly needs an app for voice calls, this one is it. The UI and design are also updated regularly despite the fact that the technology is relatively old.
