It’s fairly straight forward I’d say. The guide is pretty well written. Vanilla is indeed vanilla but seems to just run better. I have not found details as for a simple way to execute AT commands yet. Nor band lock or verify CA. This is actually just as much of a headache for someone just wanting it to work.
I followed this guide here Big thanks to them.
I was replied to about AT commands and got linked this here
Will likely just be returning this product.
