Check in the Three app that your spend limit isn't set to zero. 

Also, check with Customer Services that your credit limit isn't set to £1

Are you actually picking any network signal whatsoever. Is data roaming switched on? Try doing a manual roam and selecting the network manually rather than letting the phone pick the network automatically. Switch the phone off/on.
