You also need to remember that you can *only* top this one up in £15
increments.

When I looked, earlier this year, the situation was:

Vodafone, more expensive per MB but the top-up doesn't expire
(except in the most unusual circumstances of not being used for 6
months account superseded, not being used for a year account
exterminated).

Three, cheaper per MB, but the top-up vanishes after a month no
matter how much is left.

Conclusion, light data users should use the Vodafone one, heavy data
users should use the Three one. Where is the dividing line between
them? People should get off their backsides and not expect spoon-
feeding. People can work this out themselves for their anticipated
use.

T-Mobile also did one, though the pricing for this was too
complicated for my pretty little head. Pay per day, week or month
IIRC. Payment involved sending text messages IIRC, how old fashioned
and primitive.
