Text messages can be sent to another country using the same number?

Could you please help me in the following?

1. I'm living in US and I sent text messages to a US person just traveled to China and Taiwan. I sent the messages using the same number that I used to call this person when he was in US.
Do you know if he will receive it in China/Taiwan please? ( I didn't add any international code in front of his iphone number)

2. If he can't receive it due to some reasons in China/Taiwan, will the message be sent to him after he comes back to US?

He's the one who doesn't like to get duplicate text messages, and he's been a bit mad at me recently. So I don't want to just keep sending messages, and I don't want to call him until later.

Actually, if he still using the number normally in China, he can receive your text message. Don't worry.

  • Why do my iPhone messages keep getting sent to my phone and another phone? Whenever a message gets sent to my iPhone 4, my brother in Vermont also gets them on his iPhone 4S. So like ill be texting my friend and he can see the entire conversation and he can type. I don't get his messages though. I just wanted to know if there's an easy way to fix this because it just started happening about three weeks ago and none of us have gotten a new phone in a year. I'm not sure if it happened when he went back to College and he crossed a state border?
