If you're unable to locate the PUK code via your My Verizon account, you'll need to contact Customer Service, assuming you have access to another phone, or use the chat option via the Contact Us link at the top of the page (if you're using the desktop version of the forum). Your local corporate VzW store may be able to look it up for you.
Were you not able to locate your PUK code via your My Verizon account? You can Request the Desktop Site of the forum via your browser settings. This is primarily a customer-to-customer forum and responses by VzW reps aren't guaranteed; when they do answer, it's sometimes a few days.
In this situation, if there is no other mobile browser you can download to use and no other phone to call from, store to visit, or computer to use, you might can try Skype or similar to make a wifi call. Outside of that, I'm out of ideas.
Have you tried clicking the Request Desktop Site in your browser settings and then manually entering the www.verizonwireless.com web site address? That usually works for me.
