Your old SIM will continue to work for about 90 minutes to 2 hours until porting is completed. Once your old SIM stopped work and is showing SOS then power off your phone and switch to the PM SIM and power the phone back on.
@KathySmalls Yes try the PM SIM card in the phone and reboot the device and test both incoming and outgoing calling calls and text and data
Adding @KathySmalls I made a thread on this before as it says it will tell you know when to change SIM cards but dosent until you do and go back inthe account for the first time to confirm full access check it out here
