MC60CA-04-STD does not respond to AT commands. I tried different firmware versions (MC60CAR01A13, MC60CAR01A05) but the result is always the same. However, when the SIM card is not inserted, the MC60 responds to commands. At the same time, GNSS always works perfectly. Does anyone know what’s going on ?
Hi,
If you do not enable the GNSS function, will the AT command run normally when the sim card inserted?
Hi. No.
+CSQ: 99,99 Always.

After that, the module stops responding and turns off. When I turn it on, the same thing happens.
Hi，
Do you mean there is no signal after the module is inserted into the SIM card？Please confirm whether the antenna is connected properly and whether at+cfun? is +CFUN: 1.
If it still doesn’t work, you can insert the SIM card into your mobile phone to confirm whether you can surf the Internet.
// QNavigator_V1.2
This is without a SIM.

The module stops responding to AT commands. The module is being turned off.
В мобильном телефоне сим карта работает.
:размышляющий:
It could be power supply issue. When the module tries to attach to the network, it draws more current and
may power off the module.
So please check the power supply.

It was hard to believe. Indeed, the problem was hidden in the power supply of the module. Thank you for your attention.
