I got a tmobile nano sim and put it in my iPhone 5, then I restored it and iTunes said congratulation your iPhone has been unlocked. for some reason on the top it's saying no service. I asked the tmobile guy at the store to double check if it was activated he said it was, he told me to call customer service I call them and they said there's nothing wrong with the sim its perfectly active. I tried restoring and setting it up again but still the same problem. what can i do? i already got it unlocked and made sure it was unlocked
