UK prepaid to use in Paris
 

I'll be visiting London, then Paris, then London for a few weeks. We"ll have old non-data gsm phones (band 900/1800/1900) which I think will work OK in London and Paris. Buying a prepaid sim in Paris doesn't seem to be worth it (not just $) but London will be no problems.

So.....what do UK people find is the best UK sim for useing both in UK and Paris? 99% of the calls will be to each others phones. Please :o or I will have to go out shopping with HER in Paris.

Asda mobile is quite cheap....as is Tesco mobile....
