Here’s a list of Best voice calling apps for Android which you can use to call people using your smartphone or tablet without incurring large cellphone bills. Most of these app are very popular, but I decided to cover them for all those who might not know about apps like Viber, Skype, and more, but who would like to talk for free and without paying large sums of money other than money spent on Wifi or 3G, which is a requisite for these apps.
Viber is one of the most popular if not the most popular voice calling, text messaging, photo exchanging apps in the world. A phone number is required to register an account, but once you have an account only an active internet connection is required to communicate with your contacts, at least those who use Viber.
Viber will find which one of your friends also uses it by going over numbers from your contacts app, and also by connecting to Facebook and checking there if you allow it of course. Next to messaging with photo support, voice calling there are also group chats for up to 100 participants. Desktop Viber apps are available for Windows and Mac so if you want to use it on your laptop or desktop at home, you can.
Skype – free IM & video calls
I said that Viber is the most popular voice calling app, but Skype is also somewhere up there, trailing close behind on second place. Skype is available for Linux, Windows, Mac and of course it’s also on Android.
Skype has voice calls, video calls, text chats, file sharing, and the best part it all works across devices, meaning you can communicate with people using the desktop app from your phone and vice versa.
LINE: Free Calls & Messages
LINE is another voice calling app that has it all. Next to voice calls it also comes with video calls, text messages and it all runs via WiFi, to save you money on your cell phone plan.
LINE is also cross-platform, it’s available on iPhone, PC, tablets and more. Accounts have to be registered to use the app, and it can also sync up with your cell phone number to check which one of your contacts also uses LINE, but unlike with Viber, this isn’t a pre-requisite to use LINE. LINE has a social component to it, allowing you to post status updates to a timeline for your friends to see.
ooVoo Video Call, Text & Voice
As you can see from its name, ooVoo once again has everything you need, video calls, voice calls, texts and over 90 million people who use it.
It’s not a requirement, but ooVoo can also connect with your phone number and check which one of your contacts uses the app. It’s also possible to invite contacts from Facebook, Twitter, email to join ooVoo and be your friends there also. App supports group chats of up to 12 users.
