I can't link my service to profile why
When you login to My Verizon, does the URL say "guest" in it anywhere, or are you getting a message saying something like "You'll get the full Account Owner experience when [something] is active"? If either of these is true, then what happened was you got a guest account instead of an actual one. Usually this is caused by registering on My Verizon a bit too soon, before the system has refreshed to show you are a customer.
Despite any messages indicating otherwise, you cannot link any services to a guest account and must create a new one. You can do this either by using the create new account link in the My Verizon login page, or try this alternate link:
