Note to AIS network engineering:
In the same building next to the beach, but on the opposite side of the building (the city side), the AIS NB-IoT shield will not connect to the network. In fact, it connects easily on the sea-side of the building, but on the city-side, even though there are many cell towers, the shield has never connected:
At least, we know this was set and AutoConnect is working
