Nope it can't

Hi guys, my house system has already chanted to tp link mesh routers and now the maxis router and dongle just sit in store room. Next month I'll need to work out station for 3 days and needed WiFi. If I bring the old maxis router and dongle and use it in other state for 3 days, while my home fiber still using, will I get banned? Actually I don't mind get banned as my new tp link mesh routers didn't use the backup sim also. But I affraid my WiFi service got interupped when I halfway working.
