I’ve never had good luck finding cellular devices that you could just put a SIM card in (on a standard 4g/5g line). I remember buying a data SIM from T-mobile only it not working in a cellular security camera. So I just stuck with a cheap 5g phone, sharing data to a rpi over usb, which provides ethernet to a travel/low power AP.
