Hi, I am working with Raspberry Pi 3G/4G<E Base HAT and quectel EC25-E

Bus 001 Device 008: ID 2c7c:0125 Quectel Wireless Solutions Co., Ltd. EC25 LTE modem
The module is responding successfully to AT commands, however, it does not detect the Sim Card. I just tried 2 different Sim cards, but same behaviour. Any ideas?
+CME ERROR: SIM not inserted
I just unplugged the hat, and inserted it again. It works now. Weird…
