Xfinity Mobile Visual Voicemail
How can I set up visual voicemail on my phone? It does not give me the option anywhere. If I go into the Phone app and go to the voicemail tab, the only button is one to "call voicemail." I contacted Xfinity and their "solution" was to install a third-party app called HulloMail that requires a subscription fee. I’m not doing that, and I don’t know how they could think that was appropriate to suggest. What can I do?
