It's kinda funny, well not really, but it seems everyone is asking if the phone works in a particular zip code. My guess is you purchased it at a local store only to find out it does not work locally.
Calling customer service, they can tell you and if you activated your phone card, again, if customer service knows and they must when it's activated that it will not work in your local zip code area, Trac Fone needs to correct that also. By the time you figure it out, depending on return policies you may get stuck with a phone you cannot use. and Trac Fone is suppose to work EVERYWHERE! Right?
Check out the zip code, you can also check it by going online and putting the LG840 in, there is a space at top to enter the zip code.
