I am abroad now, and my domestic mobile phone is with me. I don't have global access. Can I get a short message from China on the Internet? (Non-Fetion)

You don't need to open GSM, just open international roaming. Without international roaming, there is no signal when going abroad, and it is not in the service area. All services related to mobile phones have stopped, so there is no need to talk about receiving information.

Would you like to ask if you can receive information on your mobile phone or online?

If you receive other information online, it doesn't matter to give it to your mobile phone. Of course, it is possible.
