It depends a bit on the operator. The guidelines say that NEW SIM cards must be monitored for at least 4 months before a breach of the FUP can be established. On existing SIMs the rules say more than 50% consumption or more than 50% logged in the roaming network in a 4 month's period. So theoretically, they can charge you extra already after 2 months. But they will tell you in advance and the max. total "abuse" rate is around €9.50 per GB (as long a plan is activated). But this can only be done, if explicitly stated by the operator in the T&Cs or other documents before.
