NTSA status 'unpost' means your smart driving license is not activated because you have a pending payment. Make sure that you have completed your payment for any of your pending applications in NTSA TIMS account. After payment the status should change to normal.
Also make sure that you have paid ksh. 750 for pdl before you apply for smart driving license.
You can as well email: email@example.com. if takes longer than usual for the status to change after paying.
