From 1st June Vodafone are changing the way they charge for data.
Reading between the lines web access will plateau at £1 per day for up
to 15MB, but other IP access will cost £2 per MB (down from £2.35 now).

My contract (which still has another 11 or 12 months to run) currently
includes £30 of data/SMS, which is 250 text messages (at 12p each)
interchangeable with data at £2.35 per MB. If I continue the same usage
(~10 MB per month, and a handful of text messages) my bill will increase
from £25 per month to at least £45 per month, but with each data session
now to cost 5p, it would probably go higher as my phone checks for new
e-mail, which would normally only send a few bytes.

Given this is a detrimental change to the consumer, does anyone have any
experience of how Vodafone handles this? I will contact them in a few
days - experience has taught me the operators do not always know about
new changes as soon as they appear, and trying to explain the difference
between ssh and http protocols, so as to ask if they are charged
differently might be hard!

Cheers,

Mark.
