Does o2 4 or 5g home broadband slow down after a certain amount of usage even if you have an unlimited data plan?

Unlimited is not truly unlimited, and as a rule anything over 650Gb could be construed as not within the FUP,  and o2 reserve the right to use traffic management.

And in fairness no UK network offers true unlimited data...
