The telecom card used by s9 only has 4G network after the volte HD call is started, so it is impossible to send and receive short messages. How to solve it?

Samsung S9 mobile phones generally recommend the following steps for troubleshooting and handling:

1. Check whether you can make a phone call, and rule out whether the phone bill is insufficient or the network signal is unstable.

2. If the call is normal, please check whether the SMS blacklist function is set.

3. Check whether the information center number is entered correctly (hint: the telecom card has no information center number setting).

4. Try to replace another SIM card.

5. If it is invalid, please back up the information (contacts, pictures, etc.). ) and restore the phone to the factory settings.

If the problem still exists, I suggest you take the purchase invoice and replacement card and send your mobile phone to the nearest service center for testing.
