Cellular Router

I'm looking to build an Openwrt router that can connect via 4G to our local provider. The provider is known as Altice mobile and requires the use of a SIM card. Altice is actually a combination of AT&T and Sprint towers here in the USA. What are my best options for getting a cellular router going here at my cabin?

  1. Is there an off the shelf router that I should be looking at that includes all the necessary hardware?

  2. Is there a USB dongle that OpenWRT supports that I can plug into my existing router?

TIA.

Several.
But you need to closely look into the specifics, so that the hardware is really supported by Linux.
