The Good The HTC One flaunts a stunning metal design, a powerful quad-core processor, and a beautiful 4.7-inch, 1080p screen. It runs Android Jelly Bean, takes great pictures, and has a feature-packed camera app.

The Bad The sealed case design means no SD expansion slot or user-replaceable battery. The BlinkFeed software can't be completely removed.

The Bottom Line A few quibbles notwithstanding, the powerhouse HTC One is a beautifully crafted, near-ideal smartphone.

Please be careful while ordering the model, check the model number - details in the review below

- People who review should be careful before jumping to conclusion, this is a dual SIM phone availble in both 
a) CDMA and GSM 
b) WCDMA and GSM 
combitnations, and HTC inida website says 900 /1800 MHZ for WCDMA and 800/1900 MHZ for CDMA EVDO rev 1
So please be careful before ordering which model number you order as per my research on chinese web site and XDA forum:
- HTC One 802d is CDMA variant i.e one sim slot for 2g and other slot for CDMA i.e will second sim will work only with operators like MTS, Reliance CDMA and TATA CDMA 
- HTC One 802w is 3G/WCDMA variant i.e one sim for 2g and other for 3G/WCDMA i.e both sim will accept more popular providers like Airtel, Voda, Idea, Docomo, Reliance GSM etc. so it can work in 2G+2G or 2G + 3G/WCDMA 
at speculated pirce of INR 46,495 this seems a bit high, should be priced under 40k. i think from the specs and performance prospective this is proven one.
I was planning to buy this from China as this one already available there, but at current rupee rate this would be unwise to do. So i will wait for it to reappear here.
Detailed reviews cane be found on internet with benchmark scores, pros and cons.
Updated: i called a seller selling this product, HTC One 802d is the version that is released in india and it works with GSM upto edge + GSM upto 3G in dual active mode here, due to frequency match and it works only on a particular CDMA frequency that is prevelant in US.

Plzzzz don’t buy this !!

i bought the single sim version of this phone on flipkart .. the phone was actually awesome nd i loved it 
but just on the second day it slipped from my pocket nd fell glass facing the floor nd it got shattered completely .
,..i took it to the service center and they said it costs around 22k-27k o repair the glass and atleast 2 months for it as they have to send the phone outside india ..
it is almost impossible to repair the phone ..this uses zero gap technology and the parts are welded together ..the 1080 display too has to be replaced along with the gorilla glass ..nd the glass can only be removed using a heat gun and a suction cap..
This has got Ifixit repairability rating of 1/10 which is terribly low ( lowest ever for any phone ) .. 
so ppl .. pleast think before buying ...youll never kno when accidensts happen .. just a small drop nd your 50k is lost forever ..

Worst Phone from HTC

Please don't buy the phone by going through the 5 star reviews. This is one of the worst phone ever i had used. After buying the phone it started hanging after a month, HTC support asked "Have u downloaded the 3rd party apps". A very stupid question.
They had upgraded the phone to the newer Android version, worked well for 15 days and then stopped responding, this time they said there is HW problem, and asked to wait for 15-20 days. 
I am not sure if I will get my phone even in 30 days. There excuse is phone is new, hence will take time.
I request you guys please don't put your hard earned money in to this worst phone.
