How to handle poor contact of the physical SIM card?
- Remove the SIM card, check if there is dust or foreign matter in the card slot, and clean it with a soft brush.
- Adjust the position of the SIM card to ensure it is fully inserted into the card slot without looseness.
- If the card slot is damaged, contact the device manufacturer for repair.
- Test with another SIM card to rule out issues with the card itself.
