I bought a used T mobile phone, a note 10 plus 5g. I’m currently a Sprint customer. When I went to swap over, the Sprint representative said it wasn’t compatible. I didn’t realize some Sprint phones and T-Mobile phones aren’t compatible with each other. Am I Sol? I can return the phone. Just wondering if anyone came across this issue. I called T-Mobile and they said I could try to get the phone unlocked. Any suggestions?
