Is the SIM card carrier locked to the other phone? Who is your cellular provider? Have you called them for help with moving their SIM to another phone? If you are expecting to just remove the SIM from one phone and plug it in to another phone that’s likely not how it works depending on your contract with the cellular carrier.
