@Jihyun1 : Are you on contract or PAYG? Did you use 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.
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.

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

I'm using PAYG which I bought it in the UK. And I could use it without problem until yesterday even in Malta. And My payG date is until 20th this month. It just suddenly hasn't worked since this morning. I've already restarted my Phone 5 times..
