Comfi Phonecards Coupon Codes

I purchased a sim card for my iPhone 4 that I had unlocked. I wanted to use it when i traveled out of the country, but also wanted to use it temporarily while in the US. It comes with T-mobile. Where I am at T-mobile service kept dropping and would not work. I was turned over to a manager who really followed up and found that T-mobile is only starting to expand their frequency for the iPhone. Long story short he was able to transfer the sim card in the data base to AT&T and now the phone works. GREAT SERVICE.The cost for US calls are more than the standard but I still feel reasonable. The out of country call rate are the best I could find.
