I've only just noticed the tab on Prepaid Internet Pass here

And yes, if you need that much data within the 3 days, then those seem to be the steps.
However, do you need 2GB within 3 days? If not, I believe those under the Prepaid tab can also be used, despite the Prepaid Mobile Internet Add-Ons label. Like I recall having subscribed to something like a weekly RM10 500MB (thereabout) plan before... Just need to remember to cancel the auto-renewal before the expiry.
You can try subscribing to one of the other plans instead, if you want, and go step-by-step just in case.
Digi network may not be as good as the likes of Maxis (Hotlink), but still very much usable by my standards - and I'm an impatient user who likes no-nonsense connection.
Hmm... Digi seems to have made some updates to their website recently or after the Digi New Best v1 pack was launched. Will have to find a chance to explore in order to understand what's going on myself...
