Adding a feature to measure cell service data use would allow remote user of the Reoloiink Go PT to reup their data amounts with their cell provider before the camera looses connection due to a data plan runninng out.

@moon_487041754812578 Thank you for your suggestion. I will forward it to the R & D team for evaluation. You can also check your data plan on your SIM card service website now. That will be easy too.
