S4 long message cannot be received.

If the mobile phone can't receive long messages, we suggest that you follow the following methods:

1. Edit a long short message on your mobile phone and give yourself a try.

2. Try to change another SIM card to receive SMS.

3. Back up the data in the mobile phone (contacts, text messages, pictures, etc.). ), and then try to restore the factory settings (Settings-Reset/Privacy-Restore Factory Settings).

If all the above methods are ineffective, there may be something wrong with the internal program. I suggest you take the three-guarantee certificate of your mobile phone and send it to the nearest Samsung service center for engineers to check the machine.

It is recommended that you apply for "booking to the store" in Samsung official website and enjoy priority maintenance service:/pre-order.

After the appointment is successful, please bring your machine, invoice and warranty card to the service center you reserved on time.
