Well to kick this off:
I have 4 Prepaid phones with 2DM.
Only one does not use or need any data.
Guess which one won 1GB of free data today?
A prize which is not really a prize in this case, it's actually a "Mobile Deskphone" as part of my Emergency Kit.
It has already got 720 carryover minutes / 250 Txt's per month...does not use any data.
The other 3 phones do, but already have more than enough data currently.
I'm NOT annoyed, but see the irony!
