Problem with data services on my phone

I have an LG VX8300 vCAST phone from Verizon. Since December I have been unable to use any data services and I believe a technicial problem (rather than an account issue) may be to blame. Services I cannot access include vCAST Music Store, vCAST Video, Mobile Web, My Account, Instant Messaging and other Apps that require a connection, as well as sending and receiving text messages. Since resetting all of the timers, the "Total KB" consistantly reads '0' and never increases regardless of what I try to use. What phone settings should I verify to ensure that it is configured to access the EVDO (?) network correctly? Note that I did find my way into the Service Menu for technicians, so one of those settings may be corrupted. (This menu is accessed by pressing MENU-0-0-0-0-0-0-0.) Please help so that I do not have to deal with the 'traditional' customer service experience. Thanks.

There is no way for any of us to know what settings you may have inadvertantly changed in the service menus. The best indication of EVDO access is the little "EV" indicator in the upper left corner of the screen. If you are in an EVDO market, you should see this indicator.

I would not have waited over 2 months to look for answers to this question. Take it back to the Verizon store you bought it from and have their techs look at it. Contrary to popular belief, the best and most effective way to resolve a complex issue like this is the "'traditional' customer service experience". Personally, it sounds to me like something has been turned off on your account, but there is no way to know without looking at your phone.

Have you had any success figuring out your problem?
