I loved every second of using it. So much cheaper and you can call and text from everywhere in the world as long as you have an internet connection. Being able to make calls on the desktop with a desktop xmpp client is great also. if you need help, they have a very reactive support and they also gave a chat room where the employees are very active. I used for about two years and then I stopped because some services require a physical SIM card phone number (they reject VoIP ones), and I could finally find a cheap enough plan to justify not using JMP anymore.
