Troubleshooting of telephone watch card slot

Mobile phone watches support mobile cards. I suggest you change your mobile phone card to another mobile phone, and test it to confirm whether there is a card problem. If there is no problem, you should intervene in the watch several times. It may be that there is something wrong with the card slot of the watch.

Are the cards consistent?

You are definitely not sure whether the card is consistent with the card required by the phone watch, and then insert the watch that can only use the mobile Unicom card.

poor contact

Insert the card and dial it several times to see if it is in poor contact.

Watch problem

If you try it many times and it doesn't work, and the card can use your mobile phone, you can basically conclude that it is a watch problem, please find an after-sales solution.
