Are there any voip apps that get around these charges? Not sure how t-mobile knows that certain data is a phone call? Especially when you're connected to wifi.
If you use Skype to call any number you will pay per minute (through Skype, not T-Mobile). If you call overseas using WiFi to a US number there is no additional charge. The problem was coming in when using WiFi to call a third country (Canada) while overseas (the Maldives) the person was billed the cellular roaming rate ($5.99/minute) when he should have been charged as if he had placed the call over the US cellular network since this is how T-Mobile sees the call.
