If your phone can't send text messages, we recommend checking to see if you can make and receive calls**. If not, please check whether the signal of the machine is stable and whether the phone bill is sufficient. If the phone is receiving and calling** normally, but cannot send text messages, it is recommended:

1.Check whether the information center number is correct (please contact the local network operator for the information center number, the telecom card does not have the information center number set)2Try to change another SIM card.

3.Check if the machine has firmware system update push notifications, and if so, please upgrade your phone to the latest version. 4.

If it doesn't work, please back up the data in your phone (contacts, multiple files, etc.) and restore the machine to factory settings. If the problem persists after the above operations, please bring the purchase invoice, warranty card and device to the Samsung service center for inspection.
