Congrats, just wanted to add that I was able to get out of our T-Mobile contract AND keep our phone without having to file a complaint with the FTC. I escalated with customer support a few times and was told that according to their map, we have coverage. I persisted and was given an address for T-Mobile customer care. I explained that we started the contract in a different location, and that in our new location (Monterey) after a military move, it was no longer usable. I cut off the service, made them remove all of my autopayment information so that they couldn't charge my credit card for it, and a few weeks after I sent the letter, I got a call from T-Mobile confirming they would remove the early termination charge.
I switched to Cingular, now AT&T. Reception is far better, but customer service is much worse than T-Mobile. I had T-Mobile for six years and actually liked T-Mobile a lot and wouldn't have switched if not for the reception problem. With T-Mobile, I simply showed my military ID card at the local T-Mobile store when I signed up, and they put the discount on our account. With AT&T, it took many attempts and months to finally get the military discount applied to our account, it could never be completed by visiting the local AT&T retail store.
P.S. If anyone needs the AT&T Foundation Account Number FAN, send me a private message with your military email address and I'll send it to you. I was going to post it, but I couldn't find it anywhere else on the Internet and didn't want to potentially cause any trouble with posting it.
