About 國際 sms(10mark)

like i am using one2free, u need to register to have 漫遊 first, but when you type the tel. number to send your MSM, you don't need to add any area code in the front, just like sending MSM in Hong Kong. Last time my sister sent me a MSM to Japan, she just needed to type 9123xxxx. DON"T add anything in the front of the number even you send to JAPAN, alright?!

yes
just like you send normal sms
