Prepaid phone cards

Note sure this is the right topic (will post in good/bad deals also).
Which are the cheapest pre-paid call cards for International calls (Europe mainland)?
Which ones can be also used from mobile phones?
Thanks!

Hi Campeda,

Welcome to AAM.

Sorry to be the bearer of bad news but unfortunately it is breaking AAM's posting guideline 5 by posting the same question twice. I'm sure you will appreciate it is best to keep all replies to the one thread.

I will close off the now.

Hopefully you will get some help here.

Thanks,

Sueellen.
