SIM card compatibility/board not connecting #61

Closed anders624 closed 1 year ago

anders624 commented 1 year ago

I purchased a couple of the 7600G's, but haven't yet been able to send/receive anything. I've tried every example sketch provided, but none of them work with either of the two boards I've purchased.

I'm using a Verizon SIM that I got through Simetry who are providing the service.

I feel like I've tried everything, but I've also never worked with cellular communication so it's likely that I'm missing something obvious. At this point, my best guess is that the SIM card I'm using isn't compatible with the board. I'm hoping someone here can help me straighten it out.

Issue resolved by adding these lines to my code:

SerialAT.println("AT+CGDCONT=1,\"VZWINTERNET\",\"0.0.0.0\"");
SerialAT.println("AT+CGDCONT=2,\"VZWINTERNET\",\"0.0.0.0\"");
SerialAT.println("AT+CGDCONT=3,\"VZWINTERNET\",\"0.0.0.0\"");
SerialAT.println("AT+CGDCONT=4,\"VZWINTERNET\",\"0.0.0.0\"");
SerialAT.println("AT+CGDCONT=5,\"VZWINTERNET\",\"0.0.0.0\"");
