Hi all.
I ran into such a problem. Iphone XR not accepting sim card after reset and update to ios 16.2.
I am not a US citizen and do not live in the US. I bought this phone in October 2019 on ebay from the seller - https://www.ebay.com/fdbk/feedback_profile/pskrusa. This phone was sold as globally unlocked.
When I received it, I activated it without any problems and worked with it for 3 years.
In February 2022, I disabled updates.
In December 2022, I decided to sell it and logged out of my Apple account on the phone and wiped all data. But I forgot to take some screen shots from the phone for sale and reactivated it. After that, the phone was updated to version 16.2 and none of my sim cards (including the one that worked in this phone for 3 years) did not work on the phone.
I contacted Apple support for clarification and they said that the phone belongs to US Sprint.
At the same time, they confirmed to me that the phone was activated normally, it was stolen, not blocked. They also said that the phone was not listed as hacked and was activated only once (when I did).
I have already written to the seller, but he is still silent.
Apple support suggested that I contact the provider directly, but I did not find an email to write to them. And on the phone, because of the average knowledge of English, I can not understand what needs to be done.
If anyone faced this problem, please write, what should I do?
