What should I do if my Samsung Galaxy 4 phone is slow to receive text messages?

If there is a delay in sending and receiving text messages or multimedia messages on your mobile phone, we recommend that you:

1. Try changing to another geographical location. The signal strength may be weak.

2. Remove the SIM card and reinsert it; or try another SIM card.

3. Try upgrading your phone/tablet to a newer version.

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

If the problem persists, it is recommended that you bring your purchase invoice, repair card and machine to the local Samsung service center, and professional engineers will help you detect it.
