I have a SIM800L module and I want to send SMS. But this module is not connect to network. I am from Sri Lanka.
I am using 3G SIM card and I think it is not issue because if it 3G SIM it can shift to 2G. Am I right? I put this SIM card to my iPhone and change setting to 2G then also get signals “E”.
When SIM card is in the module and call to this SIM number(Module), it says Phone off. Not showing ring ring in AT terminal.
Signal LED also blinking faster not slowly.
I get AT commands response. I tied following commands.
AT+CSQ +CSQ: 0,0
Thant means no signals but…
AT+COPS=? Call Ready SMS Ready +COPS: (1,"Hutchison Lanka (Pvt)","Hutch","41308"),(3,"Mobitel","MOBITEL","41301"),(3,"CELLTEL INFINITI","CELLTEL","41303"),(3,"41305","41305","41305"),(1,"DIALOG","DIALOG","41302"),,(0-4),(0-2) OK
I can get networks. My sim card is Hutch. That means Antenna also working fine right? How to check Antenna also (Specific bandwidth)?
AT+CSCS? +CSCS: "IRA" OK
How to sole this problem? Is there have any AT command to set or check?
Please tell me what is the status of this module. is is connected to network, is it have some problem with SIM or Antenna or module?
