2 months ago Some additional info: When sending AT+COPS=? It returns a list of operators. Just as it should. When sending AT+COPS? Returns +COPS: 2. When sending AT+CPSI? Returns +CPSI: NO SERVICE,Online With the register AT commands I get: +CEREG: 0,4 +CGREG: 0,0 +CREG: 0,0
[ x] I have read the Troubleshooting section of the ReadMe
What type of issues is this?
[ ] Request to support a new module
[ ] Bug or problem compiling the library [ ] Bug or issue with library functionality (ie, sending data over TCP/IP) [x ] Question or request for help
What are you working with?

Scenario, steps to reproduce
Trying to connect using the library function gprsConnect(). It loops trying to connect and fails everytime.
Expected result
Module registered and connected to network
Actual result
Module can't connect. NETOPEN returns 1 and loops trying to connect with the same result every time.
