How do I see my account
Assuming your service(s) with Verizon are up and running, you'll need to register on My Verizon, either via the PC website, or through the app. The link below has more details:

If your Verizon services aren't active as of yet, wait until things are running before you register on My Verizon. If you do it too soon, you get a guest account instead, which doesn't "work" and won't let you link your services.
