T Mobile is useless. I was left stranded in the middle of no-where and on the phone to them for an hour, trying to add an extra $15 to my pre-paid sim card. I was staying at a friends address in America, and have an Australian credit card. They wouldn't let me put money on it. The transaction went through on my card 11 times, then cancelled 11 times. The operators just kept transferring me to the next bimbo operator. Absolutely ridiculous. 2 hours worth of getting no-where.
