Prepaid Wireless Internet Access
 

To all of geeks:
take a look onto this brother/sister page:

It is not referring to any international card - just growing number of national, but all those who trace interational mobile roaming issue know, that data (incl. SMS, MMS, ... ) weren't subject of EU regulation.
Be brave, take a look onto your countries tariffs for mobile data roaming ...

I plan to arrange link to comparing calculator - domestic vs. roaming use of data.
Some suggestions of how to define few typical usage patterns/schemes are welcomed:
for all combinations of short (up 1-2 days) or long (about week), private or business trip.
Patterns should include, except data itself, also SMS and MMS usage during the foreign trip.

Nice start. You probably want to consolidate your entries for the UK and Great Britain into one section. If a particular sim doesn't have data in one of the "kingdoms," e.g. Northern Ireland, I would just note that.
