Activated a new Tracfone SIM and requested to port my old number from a different carrier. I followed the instructions step-by-step and got a confirmation text shortly after. While waiting, I browsed tracfone customer service to see what others experienced. Some folks said it can take anywhere from a few minutes to 48 hours, depending on the previous provider. In my case, the transfer was complete later that same afternoon. No issues, and my service kicked in right away once the number was fully moved over.
