Sim Not Supported
In January 2019 i purchased an AT&T Unlocked iPhone XS from my local Walmart. After purchasing i’ve tried activating my phone with both Softbank and AU in Okinawa, Japan, both told me that my phone was locked to a carrier. I called apple and they told me to restore my iPhone from iTunes, so i did. They also stated that in the system my phone says unlocked. I purchased a sim card from Tmobile and had it shipped out here and we called and activated the card along with my phone and still every time i insert a sim card my phone shows the picture below. Someone please help, did i just waste $1300 on a phone i can’t use??
iPhone XS, iOS 12
