I just purchased the $2.99 subscription. I have tried calling around ten different numbers and it just tells me "not enough skype credit" The plan includes unlimited calls to Us and canada as well as to mobile and landlines. I am in the US and typed +1 for the country code, the area codes and tried both mobile numbers and landlines. Everything fails. The numbers I called are all to peoplep and places around me. If i have a subscription do I also have to get skype credit to call someone? Also, with this subscription can I call anyone or do they also have to be skype members?
