I can't seem to get my cell phone working. I'm stationed in South Korea (Korea, Republic of) and I have my 8 digit phone number, plus a local area code, so I dial 010-####-#### to access my phone from local phones. However, I can't seem to get twitter to work with it.

I was told "82 10 #### ####" should work to call from the states, but I'm not so certain about texting. So, I put in "+8210 #### ####" but I'm not getting any texts. Any help available? I'm stationed at Camp Humphreys, which is near Pyeongtaek and Osan. Also, to text the USA, I have to put 002 - 1 - are code - numer. Do i need the 002, or is that what the 44 is for?
