Every time i try to send a text it says sending failed i can reisieve texts

For sending text messages :
1.go to your message settings and check the message center number to see if it is correct
2. call to your network operator customer care
3. request the message center number...
4.note it down
5. go to message settings>message center number
6. insert the number which is noted by you and save it
this solves your messaging problem ...
Good luck
