I recently activated a new Samsung Galaxy Note 22 Ultra. Regular text messaging works fine but any group messaging or picture messages cannot be sent or received.
I tried the online troubleshooting and noticed that ICCID number does not match the number printed on the physical SIM card. I am able to make phone calls, browse the internet using cellular data, send and receive regular text-only SMS messages.... It is just the group texting and picture message texts that will not send or receive.
Any thoughts? I couldn't figure out a solution for the mismatched SIM and ICCID numbers.
