Hello,
i just tried to call one of their french numbers that appear in the ordering list to find out if its a mobile or landline number. It picks up at once and plays music (at the moment something from Genesis)
As the numbers they are offering are really landlines (checked the number range) the incoming call costs of 24 us-cent can only be used to cover the forwarding costs of the virtual sim-card numbers.
In total i think they have a good offer.
Chris
