Hi @prakash , Welcome to our community!! Are your getting the problem: the module cannot register to the network? According to your log, I see that the module is getting no signal with CSQ: 99. Please help to check: - The antenna is connected to the module - Collect the output of following AT command: At+KSRAT? AT+KBND? AT+COPS? AT+COPS=? Thanks
