Have any of you used Lifewire?

Hay. Just wondering, have any of you used Lifewire? For context, it’s one of the phone systems. What would I need to do in order to sign up for it? I know I would need my own number, but is there any other option? I’m just asking as I have one follower on Ramblio who also uses Lifewire. And yes, it’s still around btw. But I was mainly wondering what would be the steps for doing this, and have any of you guys used it?
