Hi Carl. The LG 840 has a "G" at the end of the model name like this: LG 840G. That G means it runs off GSM networks not CDMA, while your area is only CDMA, not GSM.
LG 840G is a feature phone not a smartphone but there are several CDMA smartphones now available from Tracfone on their website -OR- the feature phone most equivalent to an LG 840G on their site would be the LG 305C.
The airtime card Walmart is selling will work with any of them, providing as mentioned above that it's a CDMA phone since you need CDMA in your zip code.

Carl, that seems like a really good question, but I wouldn't trust that "ALL" Tracfone Smart-phones work for your particular zip code. I think you'd need to check each model individually; even though they're under Tracfone service, I believe Tracfone has coverage deals with different primary carriers. For example, I've seen some phone models advertised with Verizon coverage -- while other models have AT&T or T-Mobile coverage.
Also, over the years I've been told that sometimes carriers "share" coverages, and that my call reception was dependent on which tower picked up my out-going call...
I would say, when you looked up online and saw that your zip code was covered, with a particular Smart phone, only use THAT phone showing the coverage available. Tracfone makes contracts between the phone manufacturer and the coverage carrier, and if you mix the two, you may not be able to use the phone you chose. Maybe confirm it with Tracfone before you invest in a purchase.
