[sqa]

Hi everyone. I am not only new to mobile but and old guy. So is it possible to find something like Skype for MOTO z6w?
I know that I can buy $10/mo from my provider, but I pref. pay if I use, not just pay, pay, pay. Maybe there is some sites that you can point at? Information, .... Do I have to unlock? I have wireless in my house and this toy connects to it without problems and what can I do with it?
Thanks
