Thanks Mike. Ive applied!

Not had a very sucessful week with this. My work phone is Vodaphone, so that
gets used most of the time.
I do have a pay monthly 02 phone (a remnant from the Barclaycard deal with
20% off all calls) but I use is so little
I have gone onto a pay 'up front' deal for £119 per year which includes a
call allowance.
I rang Customer Support to get GPRS enabled. Sorry the tariff is too low -
need to finish that one and get onto a current deal..
So I went for the PAYG. Got the sim - and got the WAP to work - but no
mobile web/ internet.
Emailed customer support this time, cost too much to ring who advised:
Thank you for contacting O2 Customer Service.

GPRS Mobile Web service is not available on Pay & Go. To use this service
you will need to take out a Pay Monthly contract and have a compatible
mobile.

so I had sort of given up until your posting tonight!

Having looked at the charges abroad - Ive seen up to £7-9 per Mb so if its
not free its quite expensive (if you know what I mean!)
