SIM NOT SUPPORTED
My sister sent me an iPhone 12 pro max from the USA. I am in Nigeria.
When the phone got to me, i inserted my Nigerian SIM card into it and the error message i got is "SIM NOT SUPPORTED". The entire phone works well with WIFI. Just that I can't use my Nigerian sim on it.
My sister said she has reached out to the service provider but the phone is not working up till now.
Please help
