hagrid: This an't going to happen I'm afraid, ... when i said to vodafone on their facebook page that they should do carry over mins they said  ''carry over mins are a marketing ploy and nobody ever uses them and then I said ''peoples usage verys month to month'' i also said if nobody uses them why not allow mins to carry over what would vodafone have to loose? they didn't reply cause they knew i was right and they just like miking the system.

This is actually kinda true with the way 2D implemented it originally, where every plan had 'bonus minutes' that wouldn't carry over, and they always got used before any carry over minutes would.

It basically meant people would either never accrue any minutes,  or would accrue so many that they would never use them and they would just expire.

Carryover on standard plans would be good though - 2D and Skinny do it.

Of course, unlimited voice would be better :D
