Dual SIM is such a cool feature and so common in asia that not having it in Western markets almost seems like a conspiracy.
Work/private phone. Burner. Try out a new network. Add a local SIM when traveling.

Cheating on your wife with some cheap floozy? Dual SIM phone with a burner chip on a temporary number is fine for that. Spring break? What happens in Vegas stays in Vegas? Sure.
But drug dealers, probably not. Bank robbers, probably not. Anything that's probably somewhat gangster, probably not.
I considered the HTC Dual Sim http://www.htc.com/uk/go/htc-one-dual-sim/
In the end I got a Nexus 4 and carried on with two phones. I was so impressed by the Nexus.
When the phone market is dominated by the carriers they don't supply dual-sim phones because they don't want people to easily switch or complement their networks. I know of at least one carrier-named phone sourced from ZTE, whose only difference from the original ZTE model is the removal of the second SIM slot.
(I guess the carriers probably liked that the system didn't use SIMs, but on the other hand, the technology has proven itself)
I bought my 3G MTK phone a year ago on Aliexpress.com. It worked fine perfectly while I was living in Europe. Then I came over and now I'm always on Edge network and network speed is significantly slower.
