It appears that Digi is introducing a new prepaid service that’s focused on delivering a fully digital experience. It’s called tapp and it looks like a direct response to ookyo by Maxis.
Unlike ookyo’s unlimited data offering for a collection of apps, tapp gives you full control over how much data, calls and validity you want. What’s interesting is its sell back feature, where you can get back credit for unused data and voice call minutes.
