Please help me if you can. I went to Walmart and purchased this Moto g power 2026 at&t prepaid phone to replace my old at&t prepaid phone, I already have a phone plan. My phone plan is call and text only, with no internet access as crazy as it sounds. The Walmart employee told me that all I needed to do in order to get this new prepaid phone to work is to simply insert my old sim card in to this new prepaid phone and it should work that easy. Well I did that and it doesn't work. Is there anything else that I should try to get the phone working? Thanks for your help.
