So you mean the SIM card also works on other SIM7000 boards? It's likely a config issue. Please see the commands mentioned on [this wiki page](https://github.com/botletics/SIM7000-LTE-Shield/wiki/Connecting-to-Network)
Are you using a Botletics board?
Make sure you have a LiPo battery connected to it with proper polarity (red wire on left side of the connector when you plug the battery into the shield)
Hmmm that's strange. You tried rebooting?
Hmmm yea I'm not sure, sorry 😬. Can it still read the SIM card CCID?
Also, to get a baseline test, make sure to load the LTE_Demo sketch into the Arduino and test it, not whatever code you had on it before. Or unplug it...
Hmm, maybe somehow the SIM card circuitry is fried. Sounds unusual, but not impossible I guess... 🤔
It already can publish to CloudMQTT and other MQTT brokers so you should be able to just change the variables in the MQTT example sketch and it should work.
Make sure you delete any preexisting Adafruit_FONA library.
The way the subscribe works is that there should be a "+SMSUB: " message that the SIM7000 sends out in serial when a message comes in for a topic you've...
