What happens when contract expires?

This is probably a really stupid question but what happens when a 12 month contract runs out.

I've been with O2 for about 15 years, they were genie mobile I think for the first 5 years or so. I've only moved contracts twice from what I can remember.

I've been on O2 iPhone simplicity for about 2 maybe 3 years and get their unlimited data.

Their 3G isn't great for coverage out of cities so I'm thinking of moving to tmobile which have great 3G in comparison. Especially now their sim only tariff is £21 for 12 months and unlimited data.

What happens after 12 months, do I loose that contract and price or can I stay on it?

Considering I think the normal price is usually £31 which is too much.

It carries on at the same price until you or they cancel it, much like how your O2 simplicty contract carried on unchanged even though they don't offer unlimited data any more.

If you don't need unlimited minutes, Three or Virgin Mobile (they use T-Mobile signal) also do unlimited data for less than £21 per month.
