S3Phone - free & lowcost calls for Android
S3 World Phone gives you free domestic and long distance calls to more than 35 countries (including USA, Mexico, Europe, China, Brazil, etc.), and the cheapest possible rates to the remaining ones! More info at www.s3phone.com
This app will allow you to call using:
- VOIP: if you have 3G or broadband internet, this allows you to make the cheapest calls
- Callback via net: even with a bad internet connection, we can start your call!
- Callback via text/sms: no internet? don't worry! your call can be activated just by sending a text message to our server!
- Virtual Number: we provide you with local numbers from USA, UK and PT; just use them to call your friends and family abroad.
Additionally, you can also send low-cost text messages (SMS) to any mobile phone in the world.
======Technical details - How it works======:
VOIP: "Voice over IP", allowing the cheapest rates. Just make sure you have enough broadband (3G, 3.5G, 4G or Wifi)
CALLBACK: By sending a request to our server, your phone will start ringing. Just pick it up and wait for your destination to answer.
VIRTUAL NUMBER: your mobile network probably gives you free or cheapest calls to specific networks or landlines. S3Phone will call one of those numbers and then automatically pass the call to your final destination.

Works really well good line and very little delay. The design could be nicer
very cheap calls. Reliable, versatile and helpful and friendly staff. I would recommend to anyone who needs to call abroad or able to use their phone on wifi whilst abroad.

Line quality is much better than viber and skype. You pay a few cents more for the convenience but still massive savings from using standard call rates
Really good and cheap calls and really make family and friends closer to call anytime anywhere.
