Mainland users of China Mobile send short messages to Hong Kong mobile phones without any "prefixes" such as 852 and 00852. Can Hong Kong users receive it?

The first question, you can try to send two, all the way, and you will know the answer soon.

The second question, successful sending means that your mobile phone is sent to the mobile server, but it does not mean that the information reaches you and is sent to another user (the other party owes money, or there is no signal, power off, etc.). ).

However, about the arrival reminder. Domestic mobile users, such as Guangzhou users, can send SMS arrival reminders to China mobile users' mobile phones, that is, when the SMS you send reaches another user's terminal, you will receive a confirmation message from the confirmation server. This is a value-added service for a fee, two wallets a month.
