Here is very exciting way to make free international/ Local calls for unlimited time. All you need is to have a cell phone and at least GPRS enabled in it, 3G connection would be better but not neccesary. Now all you need to have in order to make unlimited free calls worldwide is Nimbuzz mobile app in your mobile and create your free account. Nimbuzz offers free nimbuzz to nimbuzz calling. Voice quality is superb without calls getting drops even in simple GPRS/EDGE connection. One doesn’t need to have high end cell phone as nimbuzz works well in low ends multimedia cell phones as well. This works well in Java/ Symbian/ Androids etc. cell phones. That makes nimbuzz special. Me along with my many friends are using nimbuzz to make free unlimited local/STD/International calls since quite a long time now.
I know making free calls through Nimbuzz has its own limitations but this is just ideal for people staying/working abroad and they call their familiy frequently and spending huge money to make long distance calls. They can simply ask their family to installed nimbuzz mobile app and receive/ make absolutely free calls to anywhere in the world.
