How do I set message centre number for Smart T feature Phone?

Hi Bongumusa, On your phone, visit your message settings, select SMS or Text Messages, then choose MTN, select Message Centre and edit by deleting any number you see there. Type in +234803000000.
If you did not see the option for message center number on your device, you can put your SIM in another phone and and set the message center number on the phone and put your SIM back to your phone, it will work.
