Decide Whether To Exit A Mobile Contract Early Or Wait It Out

A cheaper deal just landed and you're tempted to jump, but the exit fee on your current contract looks steep and you can't tell if it actually cancels out the saving. This weighs the exit fee against the monthly saving and months remaining, then gives you a straight leave now or wait answer.

Help me decide whether to pay the exit fee and leave my mobile contract now, or wait until it ends naturally. Weigh the exit fee against what I would save per month on a cheaper deal, how many months are left on the contract, and whether my current usage still matches the plan. Give a clear recommendation, not just the options.
