Why do I need to allow VPN access and how does it work?

You need to provide ookyo app VPN permission so that you get the unlimited internet usage that your All Access Pack, Unlimited Pass, and PopDeal gives you. 

One-time only, 3 simple steps

1. Download the ookyo app and log-in
2. Click 'OK' to Connection Request
3. Click "Go to usage access settings page" > ookyo > Allow usage tracking
4. Keep your ookyo app installed 

Without allowing VPN access, all data usage will be depleted from your 8 GB base plan quota.
