Unlocked iPhone 7 now locked to carrier
I am starting to think this is a problem in ios 10.1.1. I purchased my phone from Best Buy unlocked. I tried to switch carriers and when I put in the new SIM card, I get the Hello screen, go through the motions and then end up with "activation required" message and it goes in a circle over and over and over. I went to a Verizon store to try a test SIM and we encountered the same problem. I went to the Apple Store and was told the phone is locked to the previous carrier. I've called the carrier and they said it was a BYOD so it's not locked but the Apple rep showed me the status when he put in the IMEI. Sure enough, it's locked.
I have factory reset and did all the required steps to no avail. I called Apple support yesterday and after 2 hours on the phone, told me that they need to escalate the issue. While researching this, it looks like it happened on iOS 8 also. The phone locks to the first carrier you use but I can't get any answers how to get it unlocked.
Has anyone heard of this? As of now, I cannot use my phone as the SIM card won't work because it's locked to the previous carrier. Why is it so hard for Apple to understand that the phone/software is broken and send me a new phone? I'm not very happy with Apple ATM.
