I’d be curious to know what carriers I could use with the dongle here in the USA..?
I’ve been trying to make an IoT project and being that T-Mobile is shutting down their 3G GSM there’s only a few IoT devices that are licensed and approved for use with Verizon and AT&T for the 4G band.
:/
Shouldn't be anything special to what you were doing with 3G, there are dozens of cheap 4G dongles or hat and certification isn't really any more special (heck Verizon even recommends and shows how to set up and configure a particular $30 5G/4G modem they connect to a Pi in their ThingSpace tutorial).
As far as plans every major carrier has 4G IoT plans, prepaid or not depending on what you want. Also look into places like Databalaze if you're doing something at scale commercially.
It’s been a while since I’ve checked ThingSpace but looking at it now they have the SixFab hat listed..
Few years ago I bought the 4G hat from SixFab because it was marketed as being Verizon certified but it never worked.
I’ll have to look into things again…
