Pros: most minutes offered for the amount that you pay
Cons: highly frequent dropped calls, when the call goes through the reception was VERY POOR and you can hardly hear the whole sentence clearly, whenever there's a problem on the bill, the customer is ALWAYS WRONG and need to pay for it even though it's obviously their technical glitch; Customer Service Hotline was ALWAYS BUSY
Summary: If you are attracted to tmobile because of its minutes, BEWARE!! You probably won't use up half of the minutes because you get too frustrated over those dropped calls, broken up reception, and occasional noise in the conversation. When I called up the customer service to report a dispute, the call dropped TWICE--and I think that already says alot about their reception quality.
I often received "mysterious charges." I always make long distance calls using a phone card to call a 1-800 number and then connect to the long distance call that I make. I got billed for long distance calls, and two of them were made at the same time with varying minutes. How the heck is that possible? The customer rep vaguely claimed that it was because their "record shows that you've dialed it straight from your phone." No explanation about why this glitch occured or whatnot since the bottom line is that I have to pay for these "mysterious" fees no matter what. I asked to speak with the manager, only to be placed on hold for over 20 minutes---an obvious sign that they are just putting my call away and waiting for me to hang up on my own. Since my contract was already up, I called back and told the rep that I got way too frustrated with their frequent billing errors, poor customer service and reception quality. The rep told me that he needs to transfer me to a specialist to help me cancel the service. I waited for more than 10 minutes and nobody picked up. I dont know if they simply had way too many customers trying to cancel their service or what. But I can definitely tell you that if there's something wrong on your bill or any dispute, you as the customer are always wrong because those pond scums wouldn't want to suck up the loss in profit in exchange for customer satisfaction. They've pressed alot of wrongful charges on my bill previously, one of the worst included a bill where I made a 350 minute phone call on a morning when I was really sick and could not even talk. Apparently they insisted that I had to pay no matter what. I probably should've known better and switched to Cingular earlier rather than waiting and end up with another absurd bill.
