Mobile phone text messages are sometimes received the next day. Is this a cell phone problem or a network problem?

If there is a delay in sending and receiving SMS or MMS, we recommend that you:

1. If you try to change other geographical locations, the signal strength may be weak.

2. Take out the SIM card and insert it again; Or try to change another SIM card.

3. Upgrade your phone/tablet and try again.

4. If it is invalid, please back up the information (contacts, text messages, pictures, etc.). ) and restore the factory settings.

If the problem still exists, it is recommended that you take the purchase invoice, maintenance card and machine to the local Samsung service center, and professional engineers will help you test it.
