@Simples2504 : Did you receive a Welcome text upon arrival?
As you are on contract, did you activate roaming on your EE a/c before leaving 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 if you are on contract you need to call CS to get your roaming activated. Try calling CS on the Freephone no. in my sig. using a web-calling app over WiFi.
An International Call add-on would be for making calls abroad from UK , not for roaming.

To phone EE CS: Dial Freephone +44 800 079 8586 - Option 1 for Mobile Phone & Mobile Broadband or Option 2 for Home Broadband & Home Phone
