Verizon may not allow your Lumia 950s to work on their network
Only AT&T may offer Lumia 950 and 950 XL in the US
The US phone market is very tough for Microsoft. While Redmond has a strong presence in Europe (with over 10% market share) and other parts of the world, the US market has been stuck at around 3% for years.
For this situation we can blame both parties – the leading carriers and Microsoft – and at the end of 2015 it seems that the things are not much different than two years ago.
According to multiply sources, Microsoft and Verizon Wireless haven’t reached an agreement about the distribution of the new Lumia 950 and 950 XL through the Verizon’s network. Furthermore, the carrier has refused to authenticate the phones to work on their network, which means that if you buy an unlocked device from Microsoft Store it won’t work on Verizon. And to make the things even worse, Microsoft has disabled the specific CDMA radios for Verizon.
As a result, Lumia 950 and 950 XL are not likely to work on Verizon”s network and all customers in the US should consider changing the provider in order to use the new models for calls and data.
As far as other carriers, AT&T have already confirmed that they will be selling the phones from November. The T-Mobile customers may also have the chance to use Lumia 950 & 950 XL on the carrier’s network as T-Mobile doesn’t apply a CDMA system like Verizon, so unlocked models do not need to be added to a system and then activated.
