When you originally buy your sim card you get 12 months validity. After that the Sim Card expires.
Previously you had to top up the validity - 50QR got you 99 days. Or get another SIM card with new phone number and start all over again. (which in the past was around 300QR unless they had their special offers on)
Now, they are saying you don't have to buy validity, it is included in your hala card recharge.
What I am unhappy about is the validity days are not accruable.
