Can GSM users receive short messages without international roaming? Do I have to open it?
In international roaming, it is necessary to open international and Hong Kong, Macao and Taiwan roaming functions and pre-store a certain telephone bill. If it is not open, you can't communicate normally when roaming abroad, you can't call the Internet, and of course you can't send and receive short messages.
Domestic roaming does not require international roaming, Hong Kong, Macao and Taiwan. Can communicate normally, call the Internet, send and receive text messages.
