Why can't Huawei children's watches always receive text messages?

Hello, please follow the following steps:

Confirm whether the SIM card is a real-name registration business card printing, and has opened 2G data traffic service, short message service and caller ID service.

If you have received the verification code before, but it is garbled, you can't get it after trying several times. It may be blocked by the operator, so you need to consult the operator to open SMS service.

I hope I can help you! ~
