Telecom free card replacement and SMS recovery.

The failure of SMS function is a very distressing problem. But don't worry, we offer some solutions to help you solve this problem easily.

Check whether the mobile phone is normal.

First, try to make a phone call to see if it is caused by insufficient phone bills or network problems. If the mobile phone works normally, then the problem may be in other ways.

Check SMS blacklist

If the mobile phone works, but the short message just can't be sent out, check whether the short message blacklist is accidentally opened. If this is the problem, please close the blacklist.

Check the information center number.

If you can't receive the short message, please check whether the number of the information center is correct. If you are a telecom user, you need to pay attention: the telecom card has no information center number setting.

Replace SIM card

If you still can't send and receive SMS, please try another SIM card. This method can solve some problems caused by SIM card failure.

Restore factory settings

If all the above methods fail, please back up important data and restore the factory settings of the mobile phone. This method can solve some problems caused by software failures.

Check at the service center.

If the problem still exists, please take the purchase invoice and maintenance card to the nearest Samsung service center for inspection. We are always ready to help you!
