Is your phone PAYG or pay-monthly?

If PAYG - had you used it in the UK first, before travelling?

If pay-monthly - did you enable international roaming, by texting ROAMING to 150 before leaving the UK?

Are you on contract or PAYG? Had you used that SIM for making calls or texts in UK before you left to go abroad?

If you are on contract, did you activate roaming on your EE a/c before you left UK by texting ROAMING to 150? Having a roaming billing add-on doesn't of itself activate roaming on your a/c. Having roaming activated on your EE a/c, not just on your device, is crucial to using your contract SIM abroad.

Often just rebooting the phone is the simple remedy. Also try selecting a network manually rather than auto. Otherwise you need to call CS to get your roaming activated. Try calling CS on the Freephone no. in my sig. on Skype over WiFi. It should be free.
