Are you on PAYG or contract. If contract, you need to activate roaming before you go. Text ROAMING to 150 to see what you need to do.
See http://explore.ee.co.uk/roaming/ee/romania for prices & add-ons.

If you have an EE Extra plan you may use your UK allowances in the EU. Otherwise you need to buy add-ons.
