Best UK SIM for data and int'l calls?

[andy]

It's a slightly movable target, and almost all networks have useful options for cheap international calls, some with more than one option per network, including their own and third party arrangements.

I'm not up to date with all the data add-ons, so I'll have to check a bit. How much use do you expect, a few kilobytes or megabytes a day, or do you want a data bundle option for a dongle?

Thanks Andy - I appreciate the help.

From my research the O2 International SIM was the best rate for calling, and good data rates too.

I need about 500 MB/week, but the more the better.
