How to change the phone number of a telephone watch

The operation of changing the mobile phone watch number is as follows: first, download the child guard application on the mobile phone, then insert the SIM card into the smart watch, then open the downloaded child guard in the mobile phone, then enter the mobile phone number of the new card, and click Send Verification Code.

Hello, the mobile APP is bound to the watch, not the sim card of the watch. You can take out the old watch sim card, insert a new card, and then modify the number of the APP baby information.

Honey, just delete the previously bound phone account and add a new one. There are two ways to change the phone number. One is to change the phone number of the watch manager. This situation is a little more complicated. Open the mobile phone watch APP and log in to the original account.

Enter the Smart Care app, click the icon in the upper left corner, click the baby avatar, click Unbind and confirm. Open mobile phone settings, enter Huawei account, click Settings, click Children's Account, and create a new Children's Account according to the prompts.
