Skype Credit cannot be purchased anymore, pushing people still on the platform to have to pay for a subscription to use certain features. Skype Credit can be used to make calls to mobile phones or landlines and to send SMS messages. You could also use Skype Credit to purchase a Skype Number, but Microsoft ended the option to purchase a Skype Number recently.
"Skype Credit is no longer available," reads the banner at the top of Skype's webpage about credits. "For new purchases, check out the monthly subscriptions or make a free Skype call to anyone anytime"
