Hi, dear! I have a B525s-65a, I am now having a problem when I insert a SIM card into the device, but the B525s-65a does not show anything, why? And I checked the manual for the device and couldn't find any solution.
If the device does not recognize the SIM card, try the following:
Use a SIM card that can fit in the SIM card slot. Using a non-standard SIM card, a micro-SIM card manually cut from a standard SIM card, or a card adapter may result in the SIM card not being recognized.
Before inserting or removing the SIM card, first power off the CPE. Do not insert or remove a SIM card while the device is powered on. Doing so may result in the SIM card not being recognized.
If your SIM card is not recognized, try powering off the device, re-installing the SIM card, and powering it on again. Or, try using a different SIM card to confirm whether the SIM card is faulty.
If the SIM card is still not recognized, press and hold the power button to force it to power off and then power on again, and try again.
