Why can't the mobile phone receive the SMS from the service desk?

Unicom will dial 100 10.

Also, switch Kolor to another mobile phone and see if you can receive it. If you can, there is something wrong with your mobile phone. No, that means there is something wrong with your card.

If there is something wrong with the mobile phone, it is usually restored to the factory settings or sent to the mobile phone repair shop.

If there is a problem with the card, find the operator, move to the mobile business hall, and Unicom will go to the Unicom business hall.
