Questions about Microsoft Lumia 950

There is only the dual SIM variant. Either you use 2 SIM cards in the device or 1 SIM card and a microSD card. All Lumia 950s are therefore dual-SIM devices.

As soon as we have the units, we will display them in our showrooms.

Unfortunately, the replacement batteries are not yet available. At the moment, we cannot communicate a concrete release date. We ask for your patience.

As far as I know, this promotion only applies to the 950 XL. On the 950 and the 950 XL there is the app "Lumia Offers". The dock appears there on the XL, but unfortunately not on the "small" one.

If the TV supports the Miracast feature, this will be possible. I don't know if all Samsung models have Miracast.

You can change the entire back cover. Then you have a choice between polycarbonate, metal, leather etc. These are the only high-end phones where this is possible.

The XL has a different button arrangement (power button is between the two volume control buttons) and looks different at the back.

No. Dual Sim variants have three slots. One for SD. Single Slim have two slots. One for SD. Memory expansion is always given.
