There is no China code in front of the received text message .. What happened?

It should be like this:

Whether to add +86 symbol depends on the mobile background where the sender is located, and most regional backgrounds have +86 characters by default; But some places don't. As far as I know, the number of +86 is directly 13 * * * * *. So it doesn't matter whether it is +86 or not. Does not affect the acceptance and sending of short messages.
