SIM Card Information: The representative may ask for the SIM card’s ICCID (Integrated Circuit Card Identifier) number, a unique serial number printed on your SIM card. This helps them verify the SIM card’s status and activation.
Network Signal Strength: They might ask about your signal strength, which you can usually see in the status bar of your phone. They may also ask you to move to a different location to see if the signal improves.
Error Messages: They may inquire about any specific error messages displayed on your phone, beyond just “Not Registered on Network.” These details can offer valuable clues about the problem.
