LTE and checking if there is coverage at all.
Another quick question, I have a Gpy, but the sim cards that I got to borrow for LTE-M and NB-IoT aren't certain if they're working. Is it possible to check if there is network coverage at all without a working sim card, with some of the Functions like lte.ue_coverage()? (This one only working for LTE I believe?) As I tried just using them with the examples in the Docs, making sure to flash the right firmware, but never ever got anything to attach.
