Note 2 SMS cannot be sent.

According to your description, I suggest you try the following methods:

1. It is recommended that you go to Settings-Applications-All-SMS-Clear Data.

2. Restart the phone to see if it is a signal problem.

3. Do you have any third-party SMS interception software installed in your mobile phone?

4. Try to replace another sim card, or wipe the contact point between the mobile phone card and the mobile phone (whether the SIM card is in poor contact or not).

5. It is recommended that you try to upgrade the firmware. (Settings-About Equipment-System Update)

If you still can't send and receive SMS through the above methods, please bring the purchase invoice, maintenance card and machine to Samsung service center, and the engineer will check the machine and handle it.
