What the hell is it that mobile phones always delay receiving text messages?

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. Try again after upgrading your phone.

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.
