A SIM not working is often just a symptom of roaming not having been enabled - which can be resolved by contacting CS via another means, if you're on pay monthly.

Replacement SIMs - be they physical or electronic - usually need to be activated on EE's UK network first.

As 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.
