- How can I check if my GSM/GPRS device can reach the network?
The AT#MobileResponseMode=1 setting will allow you to talk directly with the GSM/GPRS module.
Then the AT+CSQ command will return values that indicate the signal stength. Typically, the first number must be between 8 and 30. 8 is poor, 30 is excellent, 15 is typical. 99,99 indicates that the network is not seen.
