Hello! I using Quectel M95 and 1nce sim card, when I want to connect modem with network, modem turn off. When I send to modem AT+CREG or AT+CGREG I get reply with 0,2 value. I try with other sim cards, other antennas and supply modem from 5A labolatory power supply but I still can’t connect with network. What I can supose to do?
- if the return value of AT+creg is “ 0,2 ”,it mean that the module can not register network succesfully still 。
pls send the below at cmd to get more detail:
1> AT+COPS
2> AT+CSQ
3> AT+QPIN
4> AT+QBAND
- may I know ,what is :“turn off” , the moudle will shutdown immediately ,wont you?
normally , the reason of abnormal shutdown is caused by HW issue , pls check hw first .
1 > COPS: 0
2 > CSQ: 99.99
3 > In M95 “QPIN” command don’t exist, I used CPIN command and got +CPIN: READY
4 > +QBAND: “GSM850_EGSM_DCS_PCS_MODE”
The modem automatically turns off after some time, I could think that it is the hardware fault, but when I used the M95 modem module from an external company, the same situation occurred. It was only after a dozen or so switching on and off of the modem that it was connected to the network.
