Why can't I answer the phone but I can send and receive text messages online?

If the phone can't answer the call, I suggest you:

1. Check whether the phone is in airplane mode.

2. Check whether the cell phone signal is stable. Please turn off the phone and restart it, and then search the network again. Or try to change another SIM card.

3. Check whether the mobile phone has enough balance.

4. Check whether the call barring function is set: Phone-More-Settings-More Settings-call barring (you need to enter the password entered when setting the call barring) Note: The operation paths of different models of mobile phones may be slightly different.

5. Check whether there is a new version of the system and try to update the system after backing up the data.

6. If it is invalid, please back up the data in the machine (contacts, information, photos, etc.). ) and restore the machine to factory settings.

If the problem still exists, please take the purchase invoice, maintenance card and machine to the Samsung service center, and the professional after-sales engineer will help you test it.
