[Moto X Q&A] SOMFW:
I put a T-mobile SIM in my stock 16GB Verizon Moto x. Here is what works and doesn't.

First off, 4G works! in the South Jersey area and it is Blistering fast, I have exceeded 40MB speed test downloads twice, Several in the high 30s and I am avg in mid 20s. Uploads are averaging 20+/- . Compared to Verizon this is like comparing Fios to 1999 era dial up. the best I ever got on Verizon 4G was 14 download but average between 4 and 9 !

The Network notification switches a lot between 4G, "H" mode, whatever that is, just bars and another which I didn't catch quick enough to read ?

Battery has been amazing compared to my galaxy Nexus, I got 7.5 hours of Actual "Screen on Time" which included some GPS use and an hour of music streaming total phone up time was 34+ hours. How long it will perform like this is anyone's guess, today i got about 6.5 of Screen on time. I hope this inst a trend

Now for the bad news - Using it as a Phone. Incoming calls are fine but, making outgoing is a Pain in the A$$.

When I dial a number, (which is a hassle on this KitKat dialer) it often goes to the home screen or back to the dialer. The Call Fails. I am not sure if my dialer is buggy or its a compatibility problem. the KitKat Dialer on the Moto X is an exorcise in futility. Google are you listening? Why reinvent the wheel. All I want in my Dialer is a Number Pad! and a phone book.

When I Open dialer I see Recent calls up top, the whole middle section says all contacts and is otherwise blank, the bottom has the number pad icon, History and settings dots.

Clicking the number pad icon enlarges the bottom section, which then goes all white and removes the three icons. I have to then click the back arrow and re-click the number pad icon to bring it up the actual dialer. .

At this time I can dial. and then the call always fails on the first attempt. Sometimes it takes several attempts to go through.

When I click send on the dialer the 4G disappears and I am left with just the bars. they come back when call is done but sometimes take a few minutes to do so.

If you Kill the dialer app or swipe it away, coming back to it you will have the same issues when trying to get the number pad (two attempts) if you dont, the number pad will open on first attempt. but the calls will still fail on the first try.

I also cant use the internet when in a call, whether WiFi is on or off. Is this a T-mobile problem? I could use the net in Verizon when in a call when on 4G or WiFi

The Data is set to global mode but I have tried both the other settings. On boot up I get a warning saying the SIM is not recognized which I just swipe away.

I am also having this problem. After making a call, the music player and the phones "volume" aspects cease to work., Meaning, I get no sound out of the phone, Music, notifications alarms etc.. This happens almost every time and the only fix is a reboot

I disabled all Verizon Bloat and a lot of Moto Bloat as well This could be causing some of the bugs? But i have tested several different configurations all with the same outcomes.

Hope this helps and puts an end to the - Will it work or not questions. There seem to be a lot of Net Know it all's that flat out say a Verizon Moto x wont work with a T-Mobile SIM or some other undocumented "fact"
