When we connect to network provider, once pin number entered, then ask us to dial destination number we want to connect to, there was no tone at all after a minute or so, no busy tone, no ringing tone,.... however when we canceled the call (that never succeded), the balance decrease till zero. When we complained to customer service, they promised to credit back the lost balance, but actually they did nothing. Out of 20 quid, lucky if we can make 5 quid worth of call.

My advice: don't buy !!!
