I second easytether! I use this from my at&t Samsung s9 and it works incredibly well in USA. I have it usb to a pi which runs dnsmasq to operate as a router with both an Ethernet switch and WiFi access point. Toss on a UPS and plug it into my truck. When I’m driving it charges and they make 12000mAh batteries so it lasts a full workday. I’ve used over 100Gb from this setup per month for over a year. I also tried out a cellular hat for the pi and found that it was a pain to setup but in the end can replace the cell phone.
