What to do if you can text someone and you cant get their messages?

Try wit setting the phone's original setting. for me in the end it worked..

1st take back up of ur contacts nd needed things

2nd put a sim card which u don't want cause it will erase off all contacts from the sim too..

3rd press *#7370# and press ok. then put the factory code 12345 press ok. then its done:)

4th now restore all things as u want nd msges now goes as usual.
