Smarty will close your account if you don’t use it for six months.
Therefore, it would be worthwhile popping a note in your dairy / calendar to remind you to buy a plan after 5 months have elapsed.
Presumably, you are using your plan in a router to provide broadband, not in a phone. So, if you aren’t worried about your account being closed, just buy a new SIM card when you start using the caravan again.
