Hey Abz,
Thanks for joining the Three Community. Sorry to hear that your data doesn't work sometimes. There's not enough information in your post to tell if this is a network/signal issue, or perhaps an issue with the phone or SIM. Have you checked the coverage checker to make sure there is coverage and no faults in the area?
Let us know if that helps.
