lumia 950 Firmware update

I updated my Microsoft Lumia 950 XL firmware a couple of days ago. An advantage of having an unlocked phone I guess.

Yelp unlocked is the way to go... Now some features may not work tho.
Volte being one of them.

True but that can easily be addressed by at&t. As they are not currently allowing it; they hold the key. I understand another service provider may be offering VoLTE for the Lumia Phones.

Unfortunately for AT&T they’ll lose customers over things like this and it’s not just Lumia owners. I’ve had five phones on “at&t” since – for me - it was bell south mobility mid-90’s. Been a “mobile” Customer of a bell-at&t company since 1989; Bel Atlantic → Bell South Mobility --> Cingular → AT&T. Last week two phones were dropped off, new nexus phones purchased unlocked. Two phones are currently off contact and one with a year remaining on NEXT plan. One of those phones – mine – will always be an unlocked phone. The other two are still a question short-term; but long-term I know they will be unlocked users as well. Thus jumping to another service provider becomes easier. I spend too much money each month – was > $300 – to be limited. Others are in a similar situation and I expect more people will put themselves into a position to consider their options.

I’m not a hater of AT&T. I carry a businesses phone on that V-Network and happier with AT&T. Hated the S-Network when we were on it for business. I have no first hand experiences with the T-Network but I am now considering giving them a short-term try because of their costs being lower and maybe being more open to devices like the unlocked Lumia 950 XL.

The other two phones flew to Project Fi.

I beta tested fi. Nice product if you dont mind tmo and Sprint towers.
And you don't use a ton of data. For me I would goto fi if they had a
family plan. I have plenty of nexus devices for the 6 lines.

Any from ATT on we see firmware update for the Lumia 950? I it been for unlocked 950 XL
