they could be used as wifi only devices. or permanent navigator/mp3 player for your four wheeler. it could be a for occasional candy crush/temple run.

for quite some time now i have avoided going for a cdma only phone. at least anything north of 5-6k. it somehow always seemed like safer choice to keep world phones. specially because i travel a lot and mostly to hills where i often did not find cdma signals. just hoping these phones that i have in my family support at least one of the lte bands.
