My wife traveled to Kenya (from the U.S.), and managed to rack up over $2500 in roaming charges ($4.99/minute). We’ve called T-Mobile and they did knock off 10%, and we have set up a payment plan. But, we still owe over two grand just for talking on the phone. I think this is a bit excessive. Note that I know my wife and I should have been aware of the rates and she should not have used the phone so much. We’ve learned our lesson. I’m hoping that someone knows of some avenue we can pursue to possibly get the charges reduced further.
