Have a nokia 6230 can receive messages but cant send what do i do

by going to your message option setting and set text message.

try this code on your cellphone ##002# this code should cancel any call barring , and for the sms check the Service center number if is the same as the one of your provider

IT CAN BE FIXED BY ONLY CUSTOMER CARE CENTRE..

1st go to massage then gi to satting then turn off receive report

Hi,
check your message centre number..If its edited or deleted..u cant send or receive any messages..contact your operator for tat number..

you need to format your phone so that you can receive messages again...input this code *#7370# and then click yes...enter your security code...after that your phone will reboot...it will automatically on..so please wait until the phone open..after that enjoy texting again..hope this will help you

It is barried, blacklisted reported lost or stolen.
Not much you can do mate.

Format the phone man.

that is a problem with your sim-card setup with your provider....you should call them and explain ur issue and have them fix it.

2 - try to do a master reset

I think you need to contact your network provider, cos sometimes they instructed to allow you to send and recieve messages.
