Pros: The phone has an excellent display, is reasonably speedy, has most of the latest Android features (it runs Jelly Bean 4.2.2), is compact and pocketable, and has decent battery life. If that were all there were to it, it would be a steal at $120, compared to $230 for a Moto g LTE.

Cons: Reception, on GSM, HSPA, and LTE, is terrible. I literally have the phone sitting right next to my Lumia 521 and Moto g (non-LTE), both also on T-Mobile, and this Galaxy Light can't make calls or send/receive SMS while the others can. (And don't even try to access the Internet...) The Galaxy Light just says, "mobile network not avalable, connect to WiFi to make calls or send SMS." I've tried this in my home, at my office, and everywhere in between in my car. Where the Lumia and Moto can make/receive calls, the Galaxy Light just can't. Whatever Samsung did to compromise the antenna/RF performance probably wouldn't matter as much on AT&T or another network with stronger signal that T-Mobile, but, as it stands, in my area (suburban Boston), this phone is useless to me. The Lumia 521 and Moto g are both perfectly usable on T-Mobile, rarely losing signal or dropping calls, and usually getting 1 - 7 Mbps on HSPA. The Galaxy Light is very fast (10+ Mbps) on LTE, but only when you have a very strong signal. Otherwise, it's 0 bps on any network.
