      If your Concox Telephone device fails to connect to the network, there might be several reasons. First, ensure the SIM card is correctly installed. If it is, check if the metal sheet of the SIM card is dusty and, if so, wipe it with a clean wiper. The SIM card might also be invalid, in which case you should contact your internet service provider. You might be out of GSM service area, so move back to the GSM service covered area. Finally, the signal might be weak, so try again in a strong signal area.

      If you are experiencing bad reception on your Concox Telephone, it could be due to a couple of reasons. Radio waves may not be able to communicate with the device if you are in an area with a poor signal, such as a basement or near tall buildings. In this case, move to a place with a good signal. Alternatively, it might be a call-intensive period. If so, avoid making calls during these times.
