What is Skype? Can I make phone calls and send text messages? Does the other party need to have Skype? If not, what is the number displayed by the other party?

Skype is an instant messaging software that can send text messages and make phone calls.

If you are calling a landline or mobile number, the other party does not need Skype.

Due to restrictions imposed by the Ministry of Industry and Information Technology in mainland China, calls or messages sent via Skype cannot be displayed as a bound mobile phone number. However, when making calls to countries where foreign policies allow it, it will be displayed normally.
