RV50 with static IP Puking Data being charged for gigs of data used

Keep having a recurring issue with our modems:
I have a RV50 modem that is puking Data. I did a factory reset and reloaded the template but it did not fix the issue. The modem is using a Static IP. could this be a virus on the modem or on the sim?? I can’t be the only one who has this issue?
