I purchased a Note 10 plus that I know is an ATT phone. I am using on Straight talk network with ATT sim.
The issue is the current provider that comes up when you boot the phone up is US Cellular. Is there any way to change this? I tried getting another sim card from straight talk.
The person I bought the phone from let his friend that was going to buy the phone out his sim card in which was a USCC sim.
Pretty sure USCC doesn’t allow wifi calling so it is blocking the feature because of software.
