Used IOT plan from T-Mobile reseller SIM card. Worked great on the LTE side. The router does not allow changing the internal IP from 192.168.100.0/24. Therefore one star deducted. Port forwarding is allowed, so that was the bare minimum for me. Has a built in l2tp and site-to-site IPSEC client but I couldn't get it to work with my pfsense router, but I didn't try too hard either.
