Nokia, N79 SMS can't be sent. It has been delayed. Then a bar will appear in the upper right corner, and then there will be an arrow, so you can send MMS.

My N70 often has the same problem as yours.

I am bored to death. I suggest you:

1. Try antivirus.

I don't usually have this reason.

2. The machine system is too slow.

Or too much software.

Delete those that are not commonly used.

I suggest you try to restore the factory settings.

4. Be soft if you can't.

Enter *#7370#

The original lock code is 12345.

5. if you can't do it, you can only be hard. After shutdown, press and hold at the same time.

Call key, No.3 key, * key, and then press power on, and don't let go, wait for the phone to automatically power on and ask the time.
