I am using HTC since last 2 years and it is the best phone. with complete stylish and metallic body it looks awesome . Its cost is also very reasonable and affordable. It have great features like 5.5 inch HD screen, 8 mega pixel camera flash light, large internal memory, long battery backup and along with it come great accessories like ear plugs which have good sound quality and are comfortable for ears also data cable and charger. Its a dual sim phone so can support two different networks simultaneously. So if you are looking for a new phone go for it you will not feel cheated. It is android phone so it comes with in built great apps
The Htc desire 816 is a dual sim support smartphone which supports both cdma and gsm sim card on its one sim slot. And the second sim slot supports only gsm.
