Staying connected has never been so easy, thanks to the modern-day smartphone, keeping us in touch with our friends even when they are out of reach. With advancements in the field of communications, smartphones have also evolved in how we communicate with other people.

Thanks to VoIP (Voice over Internet Protocol) technology, users can now get in touch with the special people in their lives by using the Internet connection on their phones. Since VoIP relies on the Internet, calling someone is relatively free of charge, with the exception of possible charges for using the Internet data connection.

Here are some of the best VoIP applications that are available in the Google Play Store.


Skype is arguably one of the best VoIP services being used all around the world, and remains as popular as ever, keeping faithful to its service by giving users free Skype-to-Skype video calls. The Android version of Skype still packs a lot of punch and provides the same features as its desktop counterpart.

Users of Skype for Android version will be able to make free Skype video calls, send instant messages, and voice calls via 3G or Wi-Fi. Not only that, users can make low-cost calls and send SMS messages to other mobile users directly using their Android phones.




Once you get used to the buddy system on Fring, there’s no telling when you will stop chatting with your online buddies. Fring for Android is an innovative mobile application that lets you communicate and stay connected with your friends in a fun and easy-to-use environment.

Fring is not your ordinary buddy messenger. It is a complete package of all the best communication tools available on the Internet. Users can either choose from Fring’s list of communication services such as a 4-way group video chat, 1-on-1 video chat via 3G or Wi-Fi, or hook up with friends courtesy of the Live Texting feature.

Enjoy high quality video chat, thanks to Fring’s video calling DVQ technology that will give users the best video and audio quality possible, as it automatically adjusts to your data connectivity.




For those of you who are looking for separate lines for calling and texting on Android, Line2 is definitely the right app for you. Whether it’s used for business or personal use, Line2 is an exceptional app that serves as a landline replacement and will keep your mobile number private.

Line2 also has a built in Caller ID, call waiting, and call forwarding among its several features. There is a paid plan that gives you access to voicemail and conference calling.



Tango has already been considered as one of the best free video call/chat apps for Android. What makes Tango the prime choice for many users is its top-notch voice calls. Tango has very good quality when it comes to making VoIP calls. It also easily integrates with any Android phone. Users can have free calls via 3G, 4G, and Wi-Fi connection.

Tango seamlessly integrates with any device and is always ready to receive calls 24/7.

Another plus factor for Tango is the fact that you don’t have to disconnect when you don’t want to use the service. Tango is always connected, even when you’re not using the service. This can easily eat up your phone’s battery, since the app always stays connected to the Internet.




Viber from Viber Media, is another excellent app that allows you to make free VoIP calls using your data plan. Viber basically functions the same as Tango but has better sound quality when it comes to making calls. With the use of Viber’s cutting-edge HD sound quality, phone calls are much better than GSM calls.

Viber is simple to use and lets you connect with friends easily, as it synchronizes your contact lists almost instantly once you launch the application. Gone are the days when you had to manually set your own contacts or build usernames from scratch. Unlike Tango, Viber has good battery management and runs in the background. With over 40 million Viber users around the world, staying connected has never been so easy.



Developed by Belledonne Communications, Linphone is another popular VoIP application that lets you make free calls, as well as video calls. Linphone is not your ordinary VoIP app, as it is opensource and is constantly updated and developed by the community.

Linphone uses SIP for its connections, making your calls sound good while keeping bandwidth at a minimum. This is quite handy for users who have a tight restriction on their data plan. Linphone also offers video calls to other users using MPEG4 and H264 codecs, but it is only made available to ARMv7 devices. It also supports a wide variety of audio codecs like iLBC, G711, GSM, G722, and Silk, just to name a few. The app also introduces audio multi-call and conferencing if you have multiple users on the line. Linphone also features echo cancellation, address book integration, and call history.



Groove IP Lite

Here’s a groovy application that will surely satisfy your calling cravings. Groove IP Lite from Snrb Labs is an Android application that connects to Google Voice using VoIP.

VoIP apps couldn’t get much simpler and easier to use than with CSipSimple for Android. CSipsimple is just the same as the VoIP apps you can find on the market but it is also one of the simplest to use. CSipSimple connects via WiFi just the same as those wired IP phones but minus the connection delay.

The user-interface has a minimalist feel and pretty much resembles the stock dialer found on most Android phones. The app features multi-accounts, call recording, supports a multitude of codes, as well as themes. The only downside of CsipSimple is that it uses a higher amount of bandwidth than any other VoIP app.

  • Clothing Designer

    When did Google Voice start doing VOIP Calls (with NO third party app help)???

    • bro

      it hasn’t

    • dude

      I just got through with a call using ONLY Google Voice…dunno what bro is talking about???

      • Wise_Spinner

        Are you using Android to iPhone? Which version of Google Voice? Where is the “make a voice-call” inside the Google-Voice Android app? I can make VOIP calls with all the OTHER apps… but how do I do it WITH the Google-Voice app itself?

      • Mallacord

        No… actually you didn’t. Google Voice doesn’t have native VOIP. When you choose the option to make your call “With Google Voice” it still uses your minutes instead of your data. All it does is route your call through the google voice servers and make the call come from your Gvoice number. You’re not actually using VOIP. You need a 3rd party app for that at this time.

        For someone using google products and boasting intelligence, it doesn’t appear that you actually google anything to get the facts.

  • kabsK

    I wanted a wifi phone to make cheap calls with out a plan so I bought a Kyocera rise from virgin mobile on sale for 29 bucks and never even got a card. I just installed Google voice and talkatone and it has worked perfect. I have a mifi device so I can even take it with me in the car to make calls. Has worked perfectly so far.

  • bobby

    do you know of any free voip app for the droid

  • VOX user

    VOX Mobile Voip / Sip Phone is very good. You can make cheap calls internationally. You can buy credit for as low as $1. You can not only make cheap calls, you can receive calls also because you are assigned with a real phone number. Take note, REAL PHONE NUMBER. The voice quality is super clear compare to other VOIP apps.

    • josemazcorro

      I just try it, the interface it pretty bad, you cannot search directly from the number window. I will do the thing if it would work with google voice or any other app that has a better interface…

  • Erasmo Cepeda

    For me, the best are viber (many users) and vonage (good quality). Then talkatone (uses a number), great when you dont have cell phone signal (##@@#%&%# t-mobile!).

  • Joel

    The VOIP apps keep getting better and better, giving users a renewed experience. My first experience with has been really good. Though the app is new on the blocks, its amazing. One should really check out their Social feature, very interesting.

  • Hannah
