iphone 6s still is not unlocked even though email says it was approve
I've been trying to unlock my iphone 6s for over a week now. When I first tried, I put in the IMEI number listed on the phone when I messaged *#06# (IMEI 1) I was told that it could not be unlocked because there was an overdue payment. (There was not an overdue payment). I went into the at&t store to verify that there was no overdue payment (there was not an overdue payment).
I called customer service to get it resolved they said I was putting in the wrong IMEI number and gave me a new one (IMEI 2). I tried to input this online. After 3 days it was approved. But when I put the new SIM card in, it said the SIM was not valid to be used in the phone (i.e: it was not unlocked).
