How to close the application SMS sending failed.

Failure to send short messages is a common problem, but it is not unsolvable. This article will provide you with some solutions to help you solve this problem smoothly.

Check the call function

First, check whether your mobile phone can answer and make calls normally. If the call function is normal, it may be a problem with the SMS settings.

Confirm the information center number

Make sure that your information center number is correct. If you are not sure, please contact your network operator. Telecom users should note that the telecom card has no information center number setting.

Replace SIM card

Try replacing another SIM card to see if the problem still exists.

Firmware or system updates

Check whether the phone has firmware or system update tips, and if so, remember to upgrade to the latest version in time.

Restore factory settings

If none of the above methods can solve the problem, don't worry! You can back up important data in your phone, such as address book and multimedia files, and then try to restore the factory settings.

Samsung service center

If the above steps can't solve your problem, please be sure to bring the purchase invoice, maintenance card and mobile phone to the Samsung service center for inspection. Our professional technicians will provide you with further help.
