Please see the GitHub wiki, sections with titles "Connecting to Network" and also "Texting AT Commands". Let me know if you still have any issues! |

I am new to Arduino and telecom so please bare with me. I'm using an Arduino Uno and Botletics SIM7000A and I'm trying to run the SIM7XXX_LTE_DEMO but my network status is showing "Network status 3: Denied"
I've gone through the GitHub wiki including changing the code to set the operating band and preferred mode and the problem remains. When I tried using the AT commands for troubleshooting in the serial monitor, it did not recognize the commands, only what is already in the menu.
I live in the U.S. and I am using a new AT&T sim card.

Hi there, please see this wiki page, it should solve your problem. Use the AT+CNMP=38 command. Also, make sure that in your code you're using the right APN for your AT&T SIM card, because it's set to fona.setNetworkSettings(F("hologram")) by default. |
