I have one of these: -
MikroTik hAP AX lite LTE6 WiFi 6 Modem Router
I use it exclusively as a 4G router when at the caravan, and it works a treat - if you are not used to Mikrotik can take a little bit of time to get up and running but using Winbox is easy enough. I get 200Mbps through it when the area isn't crowded with loads of other tourists
