What's included in my mobile broadband and why do I get extra charges?

[gdot]

I have a vodafone dongle which I only pay a few quid a month for for 250mb data.  I only need it as a back-up for wi-fi failures when I need to send photographs.  However, this month I got a £15 bill for usage yet when I looked at my usage it said I had used none of my 250mb data but had charges for a total of 67mb.  Question is, why does that not come out of my usage?  Is it something to do with whether I'm picking up 3G or 2G signals?  I don;t see the point in me paying monthly if I'm going to get clobbered for charges so hopefully a little education can help me!

Hi gdot,

It makes no difference to your allowance if you are using 2G or 3G.

I am a little confused by this charge, if you’ve not used any allowance.

So we can get this checked, you can see how to contact the team here.
