For non-freestyle contracts the rules are that you can move to a tariff that was available for your handset at the time you took the contract out.

To move to a newer 3G tariff or now a 4G tariff, the option available is that once you're out of a minimum term you can renew to a new deal and get the new tariff.

If you're under a minimum term for a non-Freestyle contract you have to pay the remainder.
