Welcome to Jawwy from STC, Thank you for contacting Jawwy, You can change package from STC when choosing "Keep my STC number" and follow the steps in this link: https://community.jawwy.sa/t5/Getting-Started/How-can-I-order-my-SIM/ta-p/4777
We would like to inform you that, once you submitted your fingerprint, the changing process takes 8 business hours from 8:00AM till 4.00 PM so you have to keep using your current SIM till disconnected then you can activate Jawwy SIM.
