Why can't the second card receive SMS?

1, maybe the telephone information center number is wrong. Call 10086 for manual service consultation. If it is wrong, the customer service will provide the correct number, just change it.

2. Call to try to rule out whether it is caused by the arrears of mobile phones.

3. Check whether all the short messages are not received. If individual or partial numbers cannot be received, please check whether the information interception function (such as SMS blacklist) is set.

4. If the prompt memory is full, please optimize the phone memory (for example, delete some short messages).

5. If it doesn't work, please turn off the phone, take out the SIM card and try to insert it again.

6. Update mobile phone system version: Settings-(about mobile phone/system update)-Manual download update/automatic download update (software update/system update-update). Note: Please back up the data in the device before upgrading.

7. If it is the latest version, please back up the data in the mobile phone and try to restore the factory settings.

If the problem still exists, please take the purchase invoice, maintenance card and machine to the Samsung service center, and the professional after-sales engineer will help you test it.
