JAMB profile code service is expired what does it mean?

To check if the sim card has never been used to get a profile code just do the following 

• Go to your messaging app on ur Android phone or Apple device
•  Enter RESEND in the message box and send to 55019 or 66019

make sure the SIM card you're using for this operation has credit because you'll be debited N50

if you get a response of a jamb profile code and you want a new one then use another sim card that has never been used before.

but, if you don't get any response after sending the message then thus is a network problem

just try it 20 minutes before 1 midnight people may be using the system hence no overload, many people reported that their problem was solved after trying this
