For a bit of fun, I have just looked at the data counters on my phone, for March:
UK data: 66MB
Roaming data: 533MB
The imbalance is of course because at home or work one uses the ADSL on one’s PC.
And I am not even a heavy data user. No movies, no browsing of bloated websites (e.g. sony.com), etc. Occassionally I let somebody bottom-feed off my phone’s wifi
Now try to come up with a package which gives you value on the above usage, for roaming in any European country. I repeatedly look at this and find that Vodafone plus Euro Traveller is the best one. My bill for March is under £30, comprising of £17 for the basic contract (1GB, 100 international texts) and the rest is the £2.50/day for ET (all plus VAT).
This really shows the huge value of being able to use one’s phone for the internet connection. And why the cellular companies hate people doing it
