General SIM card issues
Q1: SIM card not detected
The SIM card does not support hot plug and play. Make sure that you have
inserted the SIM card before powering the 4G router on.
This prompt indicates that there is a problem with the contact between SIM
card and card slot. You can try the following methods:
1. If you inserted the SIM card after the router is powered on, reboot
the 4G router or perform a "Modem Reset" from the Router's UI.
2. Check that you have inserted the SIM card in the correct direction.
3. Add a piece of paper to the non-contact surface of SIM card inside
of the SIM slot so that the SIM card is contacting well inside the
slot.
4. Try another SIM card.
5. Check whether the SIM card slot is damaged and contact customer
service through the purchase platform.
Q2: SIM card not registered
1. Enter the AT instruction page and execute the
command AT+QPRTPARA=3
