Why can't I see SMS when I link Apple's mobile phone and smart watch?

Hello! You should check whether the following settings are normal:

1, whether it's iphone or Apple

Keep the watch connected. If not connected, the watch will not receive SMS notification.

2. Apple on 2.iphone

In the watch software, whether the notification > information item turns on the notification reminder of information, or chooses to mirror from my iphone.

3. Apple on 3.iphone

In the watch software, does the information item turn on the reminder of information, or choose to mirror from my iphone?

4. settings on 4.iphone > notification > whether to turn on the reminder in the message.

You should hold the watch in your hand, and the strap should not be too loose and too locked, otherwise you won't receive the notice.
