I used this service to have connectivity with friends and family but this was a complete DISASTER. not only there was difficulty in connecting to local numbers - I was charged even for attempting to connect. All dropped calls were billed for even though the call never went through.
Only an idiot will make multiple 1 minute calls to the same number if the call went though the first time and secondly in that case the call will be more than a minute but unfortunately - I was charged a dollar for each of this, thus leading to a 5 digit phone bill in less than 2 weeks.
They are cheats. So please future users, BEWARE!!!!
