SMS and MMS cannot be switched.

Delay of SMS or MMS is a common problem, which may affect your normal communication. This article will introduce several solutions to help you solve this problem quickly.

Check signal

First of all, you can try other places, which may be caused by poor signal. If it works well in other places, then the problem may be the signal.

Check SIM card

Secondly, you can try to remove and reinsert the SIM card, or try to replace it. Sometimes the SIM card may malfunction, resulting in the abnormal sending and receiving of SMS or MMS.

Update system version

If all the above methods fail, you can try to update the version of the mobile phone/tablet system and upgrade the experience. Sometimes the old version of the system will also cause the delay of SMS or MMS.

Restore factory settings

If it still doesn't work, back up important data and restore factory settings. This method can clear all the data and settings on the mobile phone and restore the mobile phone to the factory state. But please pay attention to backup important data to avoid data loss.

Seek professional help

If all the above methods fail, it is recommended that you take the purchase invoice, warranty card and mobile phone to the local Samsung service center, and a professional engineer will help you check and repair.
