But from the beginning:
I bought the Dual SIM One because I do not feel like walking around with a business and a private phone.
Private I have been from the very beginning a classic HTC One (801n) then ordered directly from O2. In my opinion, the HTC flagship is objectively one of the best smartphones on the market. From my subjective point of view the best.
So I was hooked when I heard that it should take this unit as dual SIM variant and did it myself through an intermediary from China ordered (802W model of China Mobile). When this device was officially listed here on Amazon was clear to me that I have to have these supposedly European version of One Dual SIM. (Due to a supposedly better Versorung with updates)
When it arrived in the last few days with me, but me no secret version of One quickly became aware that Amazon vertriebt here, but the model 802d - the Dual SIM variant for the Indian space. Quick clear is a this when you realize that can be set as Sparchen only English (Indian) or English (United States). The KO criterion. From the update policy by HTC, the 802W and 802d are unlikely to differ. So here is still 4.2.2. announced during my O2 already 801n awhile to 4.3 runs and 4.4 definitely be yes.
Conclusion:
The 802d is returned to amazon - who wants to use in our part of the One Dual SIM should pick up the 802W. That you get apart from the fact that it is like the 801n absolutely with a few settings in terms of language and date format, even for less than 600 euros (incl. Customs duties, shipping, etc.). The 3 stars it is only because it is the One a great device - but here just the wrong country version to an even more incorrect price.
