What should I do if the activation code I received when I switched to a new mobile phone was sent out, but I couldn't receive the SMS with successful activation, including going to the local business hall? ! The mobile phone can't receive short messages from some numbers. I suggest you try:

1. If it's an official SMS from an operator, a bank or a group purchase, please try to resend it, check the status of your sim card, and restart your mobile phone to receive it again later.

2. If it is a verification code, it is recommended to change to another location and try to send and receive it again to rule out whether it is caused by network reasons.

3. Change other time periods to receive again.

4. Verify whether the SMS blacklist function is set in the mobile phone: information-more-settings-blocked information-blacklist/whitelist/blocked phrase/blocked information-view (different mobile phones may operate in slightly different ways).

5. Check whether the mobile phone has downloaded the latest third-party software (security guards, system management). It may be that the software intercepted the message, so I suggest you try to uninstall it.

6. Try to replace another SIM card.

7. If not, please back up your mobile phone data (phone book, SMS information, multimedia materials, etc.). ) and restore the phone factory settings.

If the problem still exists, it is recommended that you take the purchase invoice, maintenance card and mobile phone to the local Samsung service center, and the engineer will solve it for you.
