The rural area may be the cause. LTE is very picky. Sometimes a small hill or whatever is in the way, and you get only 3G from the same tower. And I get drop down to 3G frequently inside buildings or while in a car.

The North American carriers are notorious for IMEI checking. I once even had trouble moving a SIM between two LTE capable phones. It is completely illogical, since it simply creates more phone work for their customer support, whom have to update the IMEI.

In Europe, maybe it is not a case of such strict IMEI checking. But if I don't get LTE coverage, my first step is always to log on to the online account. Often there is a place to choose model of phone, and that indicates the LTE capability to the network. It's not always the case. But I've had to for Vodafone at least once.
