Troubleshooting for SIM card not detected / unable to connect to the internet.
Update: 2026-07-13
1.Check the status on the 4G page to see if there is a signal. Signal with no network is usually an APN issue. 2.If there's no signal and it shows no card inserted, the card type might not be supported (frequency band mismatch) or there's a contact issue. 3.If the card works in a phone but not the device, and IMEI data is missing, it might be a hardware failure. 4.Some carriers bind SIM cards to a unique device. This is not an issue if the card works in other devices. 5.Try SIM cards from different carriers, test the same SIM in a phone and the device, and check if the device's card slot is loose.

Any height recommendations for static CPE installation?

It's best to keep them horizontally aligned with a height difference of no more than 3 meters. For dynamic installations like tower cranes, it's recommended that the transmitter be 1-3 meters higher than the receiver.
