Verizon Moto X on T-mobile

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.

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.

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.

I put a prepaid T-Mobile sim into my Dev Verizon Moto X, and I get good LTE speeds.

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.

But I'm pretty sure T-Mobile will cause it is Sim unlocked

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.

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.

4.4 and Non-VZW carriers

Which one are people having better luck with, at or T-Mobile?

can you put a T-Mobile ROM for it to work as well?

Using Verizon Moto X (locked Verizon retail) on ATT should be as good as using it on Tmobile, assuming I don't need LTE ?

Thanks.
