What do I have to do to get it working

Did you review that link? It’s all laid out there pretty well. What’s throwing you?

Looks like I’ll have to wait few a few weeks I’m on vacation. I left a day after I got my new phone and didn’t even think of it. I can get on with my iPad so I should be good until I get home. Thank you for your help.
