Help! My Happy Roam Sim card doesn't work in South Korea!

Help! My Happy Roam Sim card doesn't work in South Korea!

I travel a lot and I always use Happy Roam Sim, but this time my Sim card doesn't work in South Korea. 
I couldn't even check my account balance by MMI, I could see the MMI function menu but couldn't finish the operation.  It failed every time after I made the final choice and ask me call 1633 but 1633 doesn't work in South Korea.  I think there must be something wrong with the account or area setting, because I use happy roam with this cell phone for many times and works perfectly.  .

So now I can't see my balance, I can't buy a new data plan, and I can't see what my prepaid card number is.  Could anyone from Starhub help me with this issue and tell me what I should do now?  Thanks a lot!
