SMSC = short message service centre. It's the number used by your service provider to send texts and it needs to be entered correctly on your phone or it won't be able to send texts but you can still receive them.
Here are the notes I made when I had this problem a month ago.
This appears to be caused by having the incorrect (or missing) SMSC number. To fix, follow the following steps:
Install GO SMS Pro
Open it, go to Menu -> Settings -> MESSAGING: Send&Receive -> ADVANCED: SMS/MMS Advanced settings -> MESSAGE CENTER: Enable customised SMSC -> ON
MESSAGE CENTER: Customised SMSC number
Enter +447782000800, OK
[Optional] Uninstall GO SMS Pro
Using SMS Pro was the only way I could find to enter the SMSC number. There has to be a cleaner way of doing this but it worked for me. The number I used is that of Three UK. You will need to find the correct number for your service provider if this is your problem.
