I live in an area where there is no viable internet. Just to give the only example, the only company in our area charges (this is where you fall over laughing... so sit down) $85 per month for 4 Mbps!! That is NOT a typo.
At this point, I am willing to put out the money to start a 4g LTE ISP. I provide the gear and they pay for the service.
1- I am looking at the LHG LTE6 kit connected to a wireless router in the home.
2- As for the sim cards, I would like to here your advice on this too. Will any carrier work? I do know that the bands are important. Some bands are used by all, then some strictly used by certain carriers. For example, Nobody but Sprint uses band 25 in the USA (where I will set this up).
