True, but I think an ICQsim would be a better deal, and usually CLI works with this simcard...

Calling him with Bouygues (formule max de temps) she spend less than calling with UM or ICQ (25 cents per minute with no set up fee instead of 29 cents a minute with 25 cents of set up fee).
I think that she also have some problems using her credit card on the net to fill up the credit...
And if her husband buys a Serbian sim she will spend more than calling him on a Liechtensteinian number.

icq is the best for sms too:) if it's necessary
