Using on Other Carriers(GSM)

I am a n00b in the subject of unlocking phones to use on other networks etc.
Is there a possibility when the SPL is unlocked that we could use this on any GSM network since it is a 'world' capable phone with the GSM radio and a SIM card?
I have used a lot of WINMO phone son VZW and I flash and unlock quite often. Just had no idea how this process worked. sorry if this is a duplicate of any kind
thank you

You can call Verizon and ask them for the unlock code to your phone. The number is 1-800-711-8300, option 2 I believe. Either way you'll end up talking to a human who can do that for you. Then you'll enter the code (code A) in All Settings > Personal > Security. According to others, this unlock on the SIM will remain, even after flashing with a custom ROM.

no software to unlock the sim card, i don't want to call vz

I can buy unlock code for Imagio.

Why dont you want to call verizon? They are perfectly happy to unlock the sim for you as long as you dont have any problems with your account like delinquent payments. I called and had both of my phones unlocked in minutes and tested my ATT sim card, worked great on the aTT network

GSM 3G on america?

Did you see if you had E or 3G or H?
I've looked at the specs but haven't found the GSM 3G bands that it has.
Just this:
Digital Dual (CDMA,PCS) /1X, EVDO /Rev.A <---- perfectly clear
GSM Quad Band (GSM/GPRS/EDGE) <---- perfectly clear
WCDMA / HSDPA / HSUPA <---- not clear if it has 850mhz here
I guess it doesn't have 3G in 850mhz but I still have hopes.
Regards!

I only get "E" - my SIM is 3G capable, but the corporate plan is text-only. In other words, I can't say for certain if it will get 3G speeds. HSDPA is available here in the US, so it should be possible for an Imagio to have 3G in the States.

I called yesterday, told them I would be going overseas, they gave me the unlock code. Simple as pie. I can use my neighbor's AT&T sim card without any issues minus stuff that is Verizon specific.

The SIM unlock was easy and successful. Just call Verizon at the above number and its a done deal in 30 seconds. Will try my wife's SIM in it later.....woohoo....

because i dont have vz wireless phone number, but i need to use the t-moible or at&t, i call them, but they need me vz wireless phone number... i dont have, they not unlock for me

as i was told u are able to get it unlocked verizon will do it if ur account is 3months old and in good standing... also as far as using it on gsm not sure as of yet but will say tmobile basic signal i E in an area where out of ur basic ntwork jumpin off of another tower it will put u on H or even G but there is no 3G

H is HSDPA, which is 3.5G (faster than 3G... 7.2mbps compared to 1.5 mbps or something like that)
Edge is like 0.3 mbps and GPRS like 0.1
not really sure, but you get the idea.
Here in Mexico we have HSDPA but never get above 2mbps, at nights we do peak at 3mbps but avarage is still at much 2mbps.

Did I do something wrong?
I told them I was going over seas, I gave them my sim number and they said I was all set to go over there. Does this mean my phone is unlocked, I didn't have to put in any numbers. I will hate myself if I said the wrong thing. And if I did it right then how do I switch between sim cards and cdma?

For you phone to be unlocked they would have to give you a number to enter.
To switch between sim and cdma, go to settings -> phone -> network and change it from global mode to GSM

Not true, works fine with t mobile and at&t, didn't enter any numbers did it all from their, weird, but whatever.

I think a few things from the last three posts need clarification:
1. When you call VZW Global Support, they should have given a security code to unlock the SIM. It is a string of numbers. It is not a phone number.
2. Once the SIM is unlocked, if a SIM is present in the phone, there is no guarantee that switching back from GSM/UMTS to Global will switch the phone back to CDMA. There have been times where I've done that, and the phone has stayed on AT&T (my employer uses AT&T). I think a better method is to use either CDMA or GSM/UMTS, and to avoid the Global setting completely.

On item number 1 I would agree with you ignore my experience because even my friend who unlocks all kinds of phones for metro says it is a weird case. I have never received any unlcock cod yet it says "sim security unlocked" probably will be screwed up if I ever want to flash or reset it but whatever.
On number 2 I can't agree with you because I bought an at&t go card just for sh**ts and giggles and I have no problems, infact I can switch between the two while the phone is on, done many tests. But if anyone else experiences this issue I would like to know.

I have never heard an unlock like that. But could be... like an 'on air update'... Most times is a code or the frown upon methods (connect it to a PC or a box).
If any one wants to know, no it does not have GSM 3G for 850mhz band, not 3G with ATT and others in the world that uses that band. Tested it myself.

Even if you run at&t 3g it is much slower than verizon's. Either that or safari renders slower than s**t on brother's Icrap 3g. T mobile's is faster if you can find their 3g coverage, good luck.
PS I am still looking for internet connection settings for tmobile as I sold an unlocked imagio to my buddy and he can't get the data connection working.

does anyone ever solve de 3G problem with the 850 MHZ band... I live in Venezuela use movistar i ve the imagio sim unlocked can´t get 3G due to band restriction

Droid 4 On Rogers Wireless (Canada) - Incoming "Pay Phone" caller ID Solution

Droid 4 On Rogers Wireless (Canada) - Incoming "Pay Phone" caller ID Solution
I recently got my XT894, Droid 4 in the mail, and hooked it up to Rogers Wireless in Canada.
When I was receiving phone calls, the built in dialer would tell me that "Pay Phone" is calling, the solution to contact the Rogers Customer Care, and have them remove the "Name Display" option.
Rogers has 2 services for call display:
Name Display (which does a phonebook lookup from Roger's Side)
Call Display (the number of the dialer who is trying to dial you)
Most motorola radios don't actually support these 2 features together, so Blur reads it as "Pay Phone". After contacting Customer Service, have them remove ONLY "Name Display". I restarted my phone then everything started working properly again.
I hope this helps someone!

First off, I wanted to say that I'm on the leak 6.16.206
I also got mobile hotspot working on Rogers (this solution may apply to other rooted users running on different providers).
I added the APN settings as defined originally here: http://forum.xda-developers.com/showpost.php?p=20366961&postcount=2
Name: Rogers Tethering
APN: isp.apn
MCC: 302
MNC: 720
APN type: dun
otherwise, any other fields are showing as <not set> OR None
When I tried to add dun to the apn type, the moto UI told me only providers could add DUN types, so I went into SQLite Editor -> Phone/Messaging Storage -> telephony.db -> carriers -> Located the last APN which I added manually, scrolled over to "type" then long pressed that field, chose "edit field" and added dun. Once completed, I restarted my phone. I now have the stock mobile hotspot app working (I had to also disable the entitlement check earlier) on Rogers!

Now wait, you got a Droid 4 working on Rogers????

Yup, no LTE though, just GSM HSPA
Sent from my XT894 running ICS

I can confirm that the Droid 4 works on Rogers. Took a week of fiddling, but it works.
Received the Droid 4 with 2.3.4 installed. Did the over-the-air updates to 4.0.4. Rooted it, installed SafeStrap 3, and installed Olegfusion's CM10/JB ROM (4.1.2), and was off to the races. Shows "E", "3G", and "H" when accessing the Internet.

have you ever try with stock kernel?
I wonder not to update to CM10 right now. I have a problem, it seems to connect, 3G/H letter, bu no tranmition. I have an old jaj, Droid3 working perfectly with same APN records.
Any thing that could help me??

LTE on this phone is not compatible with the Rogers network. If you want a Rogers LTE phone, pickup the Motorola RAZR HD. The phone will operate on 3G or 3.5G, although we in Canada consider HSPA+ to be "4G".
LTE can give you rates of up to 100mbps usually gives you about 25-30mbps
HSPA+ can give you rates up to 12-15mbps I usually get 4-5mbps
I hope that helps!

The phone comes unlocked, you just have to load up ICS and throw on the Rogers APN (rogers-core-appl1.apn) and you're good. If you want to do some of the advanced features like setting up wireless tethering and stuff along those lines, you'll need root.

so you're saying that all droid 4 are already unlocked?

Yes. They are still blocked against US GSM carriers but will work fine everywhere else, no locks.

Maybe someone can help me, I'm on Rogers. I have this same issue on Stock ICS .217 and on CM10. I can make phone calls and send text messages, but I cannot receive either. When I put my sim card in to another phone, I start getting my text messages. Any ideas on how to remedy this?

Have you tried another SIM card in your phone? Sounds like you have something wired. I would also check to make sure you are in global mode on the phone.

eBay, yes.I got mine as "bad ESN" from a liquidator, it was quite a good deal. Obviously, by now you can find clean ESN versions for below $250.
Anyways, I am on Koodo/Telus. Under Mobile Networks Settings / Network Mode set GSM/UMTS and Select Network must be UTMS only, the default finds GSM which is weird because Telus AFAIK does not even have a GSM network! It has CDMA, HSPA+, LTE even iDEN but not GSM. Before I forced UMTS, phone calls worked more or less but mobile data rarely. Since I forced UMTS I get mobile data everywhere, inside buildings, all that -- I had lots of reception problems with Wind Mobile, Telus is infinitely better.

I went through the process today and got my stock Verizon 217 Droid 4 working on Telus. I verified the Telus APN settings, went through forcing GSM/UMTS and UMTS-only mode, but still have terrible reception: 1-2 bars, -100dbM. Any thoughts for getting better signal?

[SOLVED] DROID 4 Canada SMS/voice only, no data on Rogers/Fido - help!
SOLVED! see below.
Droid 4 from Ebay, $135 or something + shipping. Replacing my string of bad luck with i927's from smartphone_wholesale (aka Cell Phone Forever) on ebay (tho the 1st one they sent was great til i lost it).
SMS/Voice is fine but cannot do any cell data on it. Following all settings on fido's site for APNs the fido-core-appl1.apn doesnt work. Had to manually put it in (APN list was blank). Tried my wife's Roger's sim, it populated the APN list itself (4 of them, all combos of internet w or w/o MMS, and rogers +/- 'internet' in the name). None of them work either (they match what's in the fora here and on the rogers site, rogers-core-appl1.apn etc).
Im a bit of a newb: is my phone not unlocked properly or something? What gives? Radio is set to global or GSM/UMTS (CDMA doenst work of course). What's the solution here?
System version: 98.72.18.XT894.Verizon.en.US

Build #: 9.8.20-72_VZW-18 Feb 8 13:11:57 2013
yes mobile data is on (and roaming set to yes but phone states it's not roaming now)
every time i've added apn's and saved i've rebooted (and rebooted twice with wife's SIM in too, in case settings had to go sim -> phone + reboot, etc). No luck any way ive tried.
Thanks for help.
[UPDATE]
belay that request cadet!
Ok I just removed the wife's sim and put mine in, rebooted, and this sim (fido) doesnt populate the APN list. I was in the middle of inputting settings for it, hadn't finished and a buncha text+ came in and wifi is off (I saw I was on Edge, big blue E on status bar). Then before I could even react I had hit save, and data turned off.
Yep, removing "internet" from the APN 'type' works fine. Leave it blank.
W t f. Maybe someone can explain that shiz to me.

Gsm data is controlled via the apns under mobile networks. Ensure you are in gsm/umts mode and verify the correct apn is selected for your carrier. If there are no apns, hit menu > add apn and supply proper settings, they are either preloaded on the sim or listed on the carrier site. A quick google will also provide the correct info.
Also under data management, ensure data is enabled over mobile network. ##program ONLY changes cdma programming.

I've checked those and.the proper APNs are there. Also in UMTS mode.

There should be absolutely no problem with GSM/UMTS data connection and MMS with unlocked xt862, just enter apn manually and go.
My personal butthurt is EV-DO with non-Verizon CDMA networks as it's really the issue even if you try to hack as the phones with the same Qualcomm chipsets like Droid 2 Global.
I've became real expert in flashing CDMA settings and real guru in tweaking props and rils. But it doesn't help.
I say no Moto and no Android anymore. I'm going to buy WP8 handset as soon as it become available with CDMA. F**k Moto and Google, long live Microsoft which never disappointed me with WM handsets.

[GUIDE] Using I537 on T-Mobile and other AWS Networks

So I'm writing this guide for SGH-I537 (ATT Samsung Galaxy S4 Active) users who want to use their I537 on T-Mobile or other carriers that support AWS (Advanced Wireless Services; see: http://en.wikipedia.org/wiki/Advanced_Wireless_Services).
Initially I got my I537 and heard conflicting reports of DIY SIM unlocking being successful, supposedly some people unable to get the AWS bands. So, I played it safe and got the device unlock code straight from ATT. Everything seemed to work at a cursory glance, got LTE and fast speeds, great! Little did I know that I actually did not have AWS unlocked.
In my room I get nearly no reception and rely on a repeater to get signal and be able to do basic things like SMS, make calls, etc. I noticed that for some reason the I537 was not picking it up.
ATT runs their LTE over some TMO HSPA frequencies (AWS) and the phone by default won't do HSPA on those frequencies. An AWS unlock will allow the phone to do either LTE or HSPA on these frequencies, thus allowing it to talk to my repeater.
I followed the guide at http://galaxys4root.com/galaxy-s4-t...aws-bands-on-att-galaxy-s4-sgh-i337sgh-i337m/ but instead used the UMMS code of *#0808#
It works on the latest stock, unrooted ROM. My device was already SIM unlocked but I don't think that will make a difference for this process. I believe that one would require SIM unlock regardless, though, to use another network.
This guide unfortunately depends on Windows specific tools, so I had to use a Windows machine to do this. It's a pretty easy guide -- basically you tell the phone to expose its modem over USB, use a Qualcomm program to talk to it, do a backup of the NVRAM, and NV Restore someone's I337 NVRAM that has the AWS enabled.
It works perfectly for me and has worked for others as well (see comments on that guide). The only difference is we have to dial *#0808#
You may want to add the T-Mobile LTE APN as well:
Code:
Name : T-Mobile LTE
APN: fast.tmobile.com
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS Protocol: WAP 2.0
MCC: 310
MNC: 260
APN Type: default,supl,admin,dun,mms

Very strange. I wish I knew the ansewr to this I stumbled upon the AWS unlock guide for I337 long time before I bought the I537. I guess I was lucky that it went without a hiccup then.
And you have the special Samsung drivers installed from that site and are sure some other drivers aren't trying to pick it p? =|

I would like to add that you should change the apn name to fast.tmobile.com (from epc.tmobile.com) that's how enabled 4g LTE in my city.
I would like to ask a 'stupid' question is there a way to enable 3g? It seems to be either edge or 4g/4gLTE for me, I've never seen my phone have a 3g icon.

For T-Mobile it's not going to show 3G afaik, it will default to showing 4G for any 3G or HSPA 4G mode. If you have LTE enabled (any of the LTE modes) then it'll show the 4G with "LTE" under the bottom right side. I leave my GS4A on T-Mobile with WCDMA Preferred which seems to offer the best speeds and connections. While T-Mobile is still working on their system here in Vegas and making improvements, the LTE aspect is of no use to me and just allows me to burn up my 5GB that much faster.
To change the modes you'll have to go into the *#*#4636#*#* menu and do it, again afaik. It's the least hassle free method I've found for myself so that's what I stick with.
And I've never changed the APN from epc to fast - it's worked since I did those same instructions to enable the AWS capability. I did change it one time but the speed tests ended up being effectively the same no matter which APN I used so I set it back to the default of epc.tmobile.com and have yet to have any issues.

Yeah, good call, I'll add the APN settings to this thread.
We have LTE in San Jose and San Francisco and it's REALLY fast and way better than the HSPA+ network. And it seems to switch to HSPA+ just fine if there's no LTE.

Added TMO LTE APN settings.

while the process went without a hitch for me, I did not see any improvements
I was getting 4G both before and after, no LTE
in fact, the speed went down fron 2.5MBPS to less 1MBPS !!
So i flashed the AT&T backup back!
might be cause I am in Seattle area
(it shows HSPAP:15 in the status in either case)

HSPA isn't LTE, you have to enable that aspect manually. By default when you put a T-Mobile SIM in the GS4A it'll set itself up for GSM/CMDA usage, and you have to alter that to get the LTE working, at least I did in my case.
I went into the service menu using *#*#4636#*#* and changed it from GSM/CDMA auto (PRL) to LTE/GSM auto (PRL) and you should reconnect and get the proper 4G/LTE symbol noting the type of connection (4 with smaller G above the letters LTE).
Here in Las Vegas that's all I have to do to enable LTE (it'll show as LTE:14). I don't use it because the actual LTE signal strength is like -105 dB here at home; when I switch it over to WCDMA Preferred it increases to -78 dB and the speeds are very fast with HSPA:10 or even HSPA:15 on occasion, and LTE drains the battery more as well (in my testing).
That's my usage and experience, maybe making some alterations with your service menu can improve performance for you. T-Mobile is still doing the upgrades across their whole network so, what might have crappy signal coverage now might improve soon.
My suggestion is try each of the potential connection methods and find the one with the best signal strength and the best speeds - for me, again, that turned out to be using WCDMA Preferred, and I'm right across the street (line of sight) with a T-Mobile leased cell site, just about 1200 feet from me with nothing in the way either when I'm here at home.
Also, I've never had to edit the APN info on my GS4A for use with T-Mobile. I know the recommendation is to alter it from epc.tmobile.com to fast.tmobile.com but since mine works just by altering the radio connection and ends up getting the same speeds (I've tested both APNs), I just stick with the default of epc.tmobile.com and I haven't had any issues worth noting. I did read some comments that said in some areas to get the LTE working properly you DO need to use fast.tmobile.com, but for me I haven't - could be something to check into for yourself.

Got LTE running on the opposite corner of my building, with abysmal speeds!
the LTE coverage in Bellevue/Redmond seems to be either very spotty, or very incompatible with S4A, not sure which it is... but overall the internet speeds are better with HSPA+ than LTE in any case...
Thanks guys for you help

So I'm writing this guide for SGH-I537 (ATT Samsung Galaxy S4 Active) users who want to use their I537 on T-Mobile or other carriers that support AWS (Advanced Wireless Services; see: http://en.wikipedia.org/wiki/Advanced_Wireless_Services).
Initially I got my I537 and heard conflicting reports of DIY SIM unlocking being successful, supposedly some people unable to get the AWS bands. So, I played it safe and got the device unlock code straight from ATT. Everything seemed to work at a cursory glance, got LTE and fast speeds, great! Little did I know that I actually did not have AWS unlocked.
In my room I get nearly no reception and rely on a repeater to get signal and be able to do basic things like SMS, make calls, etc. I noticed that for some reason the I537 was not picking it up.
ATT runs their LTE over some TMO HSPA frequencies (AWS) and the phone by default won't do HSPA on those frequencies. An AWS unlock will allow the phone to do either LTE or HSPA on these frequencies, thus allowing it to talk to my repeater.
I followed the guide at http://galaxys4root.com/galaxy-s4-t...aws-bands-on-att-galaxy-s4-sgh-i337sgh-i337m/ but instead used the UMMS code of *#0808#
It works on the latest stock, unrooted ROM. My device was already SIM unlocked but I don't think that will make a difference for this process. I believe that one would require SIM unlock regardless, though, to use another network.
This guide unfortunately depends on Windows specific tools, so I had to use a Windows machine to do this. It's a pretty easy guide -- basically you tell the phone to expose its modem over USB, use a Qualcomm program to talk to it, do a backup of the NVRAM, and NV Restore someone's I337 NVRAM that has the AWS enabled.
It works perfectly for me and has worked for others as well (see comments on that guide). The only difference is we have to dial *#0808#
You may want to add the T-Mobile LTE APN as well:
Code:
Name : T-Mobile LTE
APN: fast.tmobile.com
MMSC: http://mms.msg.eng.t-mobile.com/mms/wapenc
MMS Protocol: WAP 2.0
MCC: 310
MNC: 260
APN Type: default,supl,admin,dun,mms

SIM Unlocked on T-Mobile in Orlando:
Before Samsung replaced my Active I was running MF1, this hack wouldn't work. They sent me a new replacement with MF3 Monday. This worked!! Places where I get "E" are now "4g"!!
Awesome! I was almost going to sell it for a Nexus 5 due to this problem but not anymore!

So I've gone through all the steps and now I am at the part where I add the APN but I can't seem to find the MMS Protocol section. I've also heard we should use fast.t-mobile.com instead of the fast.tmobile.com, would that matter??

Verizon Moto X on T-mobile

Hi,
Currently with Big Red but will switch to "someone" once contract is up 3rd qtr next year. Most probably because of the the price and I am sick of VZ dropping back to 3G most of the time where I am.
If I get a Verizon Moto X can I later use that on TMobile. And/rather, a Verizon Moto X can be used on which carriers - all or none
much appreciated.

If it's a developer edition then "I believe" you could use it on sprint. T-Mobile is a GSM carrier and since the only option on the CDMA phones is for global GSM for international travel that you will likely not get it to work. They don't have the radios in it to work on T-mobile. Someone correct me if I'm wrong.

This has been covered before yes it will. Verizon moto x is ( might be wrong) the only phone that is Sim unlocked besides T-Mobile and gsm developer edition. Tmobile Sim should work just fine.

Just seconding that I put a T-Mobile SIM in to my VZW dev edition Moto X (4.4), and it was SIM unlocked as expected, but also had good LTE signal, indicating that Band 4 is definitely enabled on these phones, contrary to published specs. Good news!

Can you make phone calls and send text messages with a T-Mo SIM in a VZW phone? Seems as if a CDMA phone would not work on a GSM network for calls and texts.

Yes. I haven't done it with the Moto X yet, but I did it without issue previously with both the Verizon S4 and LG G2. It's part of an FCC agreement when Verizon got LTE. It's basically GSM unlocked. Data, text, and calls work.

Most Verizon LTE phones have a GSM radio and work on AT&T and Tmobile

I made a call to verify it works, and I received text messages from T-Mobile.
I also didn't have to add APNs, it seemed to figure them out.

Sprint won't work. Cause most of the CDMA bands and LTE bands are different.

Yes, you are wrong. It does work with either a "retail" Verizon phone, or developer edition.
The big misconception is that since Verizon uses CDMA for voice and sms, that their phones only work on CDMA. This is NOT True.
Because Verizon's 4G LTE phones are "global" they support the same GSM/GPRS/Edge bands as ATT and T-Mobile for voice and data so they can be used globally on GSM carrier networks. Another little plus is that due to the FCC rules around their 700Mhz spectrum, they are SIM unlocked, so they happen to work with ATT and T-Mobile sim inserted. Since ATT uses the same bands for HSPA and HSPA+ as they do for EDGE, you can get HSPA speeds. In areas where T-Mobile's "network modernization" has refarmed their 1900Mhz edge to HSPA, you'll get HSPA speeds. In Tmobile areas that HSPA is still over AWS, you'll fall back to Edge when trying Verizon branded devices.
Using both developer and "retail" variants of the Verizon Moto X, I have inserted my T-Mobile SIM and had it work after setting the phones to "global". I've done the same with my iPhone 5, iPhone 5S, Blackberry Z10, Q10, Nokia Lumia 928, and Samsung Galaxy S4 and Note 3. Some of the phones, like the Z10 and 928 only gave me EDGE speeds the last time I tried them. The X and S4 have given me HSPA. T-Mobile recently rolled out LTE here, as putting the T-Mo Sim in my VZW iPhne 5S last week gave me T-Mo LTE for the first time. When i get time I'll have to go back and test my other devices again to see what they do.
With recent firmware updates on my X, note 3 and Galaxy S4, I have had to manually enter T-Mobile APN settings to get them to work.

Yes it does work as long as the APN settings come down automatically to your phone, or you manually enter the correct APN settings.
On a side note... some have asked if you can do the same with a Sprint phone (since they are cdma based too). The answer is..I don't know for sure, but it really depends. I haven't looked into the sprint phones to know their "global roaming" capabilities, and what radios and frequencies their devices support. I guess as long as their phones support the quad band GSM frequencies and are (or can be) SIM Unlocked, then you can do the same with Sprint phones to get at least Edge speeds. HSPA and LTE would again depend on the frequencies the sprint phones support, and the target carrier network uses.

Thank you everybody!!!
This is excellent info and more importantly very good details. I am very grateful...

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"

I have the same issues as SOMFW. Disabling LTE resolves all these problems, so it seems like it's an issue with the LTE-to-2G/3G fallback for phone calls.
When I force it into HSPA+, I have both simultaneous voice and data and no dialing issues.

How did you disable 4G? or Force it into HSPA+? Is there a setting I am missing?
Somebody else mentioned Manually adding T-Mobile APN is this something you did?
On My Moto,x when using the Vz SIM there is an APN labeled Verizon that appears on its own, On the TM SIM it was blank
Also, while on the TM SIM under About Phone / Status My phone number doesn't show, On the Vz SIM it is there and the Dialer works fine. But I still get the Dialer Bug, which is, When I click the Keypad icon the bottom area goes blank and I have to hit the back button and repeat it. This only happens if I swipe the dialer out of running apps list, Force close it or haven't used it for several hours.
Any Ideas?

These are the steps I used to turn off LTE and enable HSPA:
1) Download/install the app LTE OnOff
2) Change Mobile Network type in Settings to LTE / GSM / UMTS
3) On LTE OnOff, hit the Three-Dot menu in the top right, and select "Select radio band"
4) Select USA Band
5) Hit the Turn Off Radio button
6) Select GSM auto (PRL) under Preferred Network Type
7) Turn On Radio
The phone should show no data for a second, then 3G, then eventually an H for HSPA will be displayed.
You can also try GSM only or WCDMA preferred if GSM auto doesn't work.
Still trying to figure out how to get LTE to play nice with it.

There is a known LTE bug that causes this issue in 4.4. Check aracanexvi's thread in the Droid Ultra section. Basically we will need to leave LTE off of you want to make calls reliably.
