Skype Number should be allowed to receive text.
You can send messages from your Skype Number if you set it as primary on Skype. It would be nice if a person could receive messages on their device. A person could potentially turn a tablet or PC that only has wifi into a device that can make/ receive calls and text. Only the receiving part is missing.
I'm not sure why I can't receive text messages. A Skype # can never fully replace a phone # without it. It would be worth paying for a data plan for the few texts I absolutely have to receive.
