Hi,
could you set that the statistic of downloaded or uploaded data will be counted based on data from RMS not the modem? for example if I made an upgrade of FW the router will lost the data for RMS statistis. If I change the SIM at the router because the data exceded the value 100GB and I will change the SIM I need also to clear the data limit...and it will change the final statistic at the end of the month.
