I have an iPhone 11 with straight talk for a few years now. got a iPhone 16e at Walmart yesterday and I transferred all my data from the 11 to the 16. I tried to move my phone number and service to the new phone. I went onto straightalk.com and I put in the imei number of my new phone and then u put in my account information and this popped up. I don’t understand how it can be from a different account when I bought it brand new from Walmart. Does anyone know how to fix this?
