@achao1104 Did you config the IO for 4G reset? please retry if not.

And please note not all 4G modules support PPP protocol, for example, some modules only support ECM or custom protocols, please contact the supplier to confirm whether PPP dial-up is supported.

the 4g module is air795ug which is using the same chipset as air724ug. so I think it can support PPP.
