Edit: not sure if this is a switching problem or the way the phone is designed, but sort of figured it out...seems that the Exhibit 4G will auto fallback to UMTS when no HSDPA link is active. Just ran some speed tests and it did in fact hold HSDPA speeds, when done it fell back to UMTS. My GS3 doesn't do this...if I have 4G/ LTE available, it stays with it. Hence the confusion.
I recently purchased a new unlocked Exhibit 4G, have been testing the various roms here...many thanks to the devs...great work! Currently trying AOIP...nice!
My primary usage is on the TMO network, at my RV site on weekends. Unfortunately, 2G is the best I can get in my location, regardless of carrier.
I live in Canada the rest of the time, on Rogers with a GS3.
I was testing out the Exhibit 4G with my Rogers sim, LTE APN's were set up ok, voice & messaging are fine, but data is wonky...I will get the 'H' (aka 4G) icon for a few seconds at a time, but for some reason I keep falling back to 3G speeds. This cycle continues over and over. AFAIK, this phone should support Rogers HPSA+ frequencies (aside from their new 2600), shouldn't it?
So I'm wondering if this is due to an incompatibility with the phone on Rogers, or needing a different baseband, or could the phone's h/w be screwy? This has been happening with all roms I have tried (AOIP, Baked, Slim).
Appreciate any insight.
I am ready for a new phone, but would like to be done with Verizon once they take away my unlimited plan. I read a few posts where it is said that the cdma phones would work on T-Mobile, the carrier I will be going to next. Can anyone confirm or deny the ability to use on both networks?
Thanks
Yes a Verizon Moto X will work on T-Mobile as it is SIM unlocked and supports band 4 LTE. It should be noted that it doesn't support AWS 3G which is the main band T-Mobile uses for their 3G service. If you are in a refarmed market then they will also offer 3G service on the PCS band which the Verizon Moto X does support. Most major cities are refarmed so as long as you are okay with the risk of ending up on 2G more often then you would on a T-Mobile Moto X then you should be okay. From my understanding T-Mobile is working on having almost all of their 3G service on the PCS band in order to free up AWS spectrum for LTE so this issue should become less of an issue over time.
With kit Kat on my vzw x, when I put my T-Mobile Sim in, I must manually enter T-Mobile APN settings to get working data and SMS. I haven't tried MMS.
With 4.2.2 Roms (version that the phone came with plus camera ota) APN settings came down automatically.
I get h+ in refarmed area.

Wow, that's interesting. Also interesting that the top section specifically references Band 4, yet the actual spectrum is not called out in the technical section below.
Thanks for the info. This is a surprisingly network-flexible phone... not used to that with Verizon phones.

Most of the upper level Verizon LTE phones released this year save the HTC One support band 4 either out of the box or will get a software update for it. Verizon is supposed to be making a big push over the next few months to add band 4 LTE service which is much needed here in Houston as our band 13 LTE service is so overloaded that sometimes I am lucky to top 3-4mbps.
Quite possible that Band 4 support was added in one of the updates that was pushed out, so most documentation wouldn't reference it. Best place to check would be the FCC docs when they tested the phone.

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"

no because the sprint x is sim locked and doesn't use the same cdma setup, and the t-mobile doesn't support cdma/evdo that verizon uses for voice and 3g data
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.

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 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?

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.

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.
Ok before I begin:
Device: HTC One m7 (verizon, but works on any GSM/CDMA)
Using Straight Talk ATT.
I've been doing some research for the last couple of days. Some say LTE is not supported anymore, others say it is, but you have to force LTE.
I'm trying to figure out a way to get my phone to stay at 4g/ LTE speeds without defaulting to 2g/EDGE.
I've tried using *#*#4636#*#* and selecting "TD-SCDMA,GSM and LTE", but this later defaults to GSM/Auto.
Also status bar displays EDGE, and in settings/ device info it shows Mobile Network Type: EDGE.
This is getting frustrating because I was using T-Mobile straight talk and had the same issue. All I'm trying to do is get LTE working.
So what I am asking is: Is there a way to force my Straight Talk ATT phone to use LTE?
I live in the city, and know for sure that LTE works everywhere here.

You may have better answers in the verizon forum. This may not be an option though as I think LTE anntenna is different in that modle and wont connect to none verizon lte as the GSM radio is not the primary one. I would never advise getting a CDMA device to run on a GSM network. It alomst never gets anything other then edge.
Yes, that's the answer I have been getting.
But some said that their is a way around it.
I also have a Verizon access code from Straight Talk, but cannot activate it...
I keep getting the error when trying to activate on Straighttalk.com that the zip code i provided doesn't have coverage. It does so for every single zip code... and I mean EVERY zip code, no matter which city.
Any Idea on this?
If I could get it to work with Verizon, I wouldn't look further.
So I got a Chinese edition phone with band 2, 4, 5, 12, and 17 to fully support both TMobile and ATT network. The Global edition was missing band 17 for ATT so I didnt want to go that route. Been going back and forth with ATT a bit for the past few days since my device came in. The phone shows up and an "unknown device" on their network when we tried adding the IEMI. It will get UMTS (2g) and HSPA+ (3Gish/4G), but will not connect to any LTE or GSM. The phone supports GSM fine, so its strange that it wont do normal cellular connection over that, it will only do cellular over UMTS. The device wont detect as an LTE device and so the sim wont activate LTE on it.
Anyone else with ATT have this issue? And were you able to resolve it somehow?
Or those with TMobile in the US, are you able to activate the phone fine and get full coverage and LTE working?
I messed around with the connection settings in the *#*#4636#*#* menu. Only the "LTE/TD-SCDMA/UMTS" and "LTE/TD-SCDMA/WCDMA" will work properly at all. Both options give me UMTS for cellular, and HSPA+ for data. Of the 4 APNs that ATT uses, only the "ATT Phone" will work at all. The standard LTE APN "NXTGENPHONE" will leave the phone with no data or cellular service. This is related to the phone not being detected as an LTE device and the SIM not activating as such.
I simply put my AT&T sim in my China version and it worked straightaway. I didn't have to do anything else.
I am on Cricket, which leases service from AT&T, so I should know if it works once it comes Tuesday.
Just for perspective, I got a EU version of the Mi 9. Popped in a T-Mobile sim and it worked out of the box. Try the other sim slot. Could be your sim card if not.
Try these codes in Dialer. See if that helps anything.
VoLTE *#*#86583#*#*
VoWIFI *#*#869434#*#*
I was just making an ATT account so no previous activations or sims. So that could be the issue. I will try activating a sim with an old phone and then move the sim over. Or since it is the same hardware as a Galaxy S10, ill see if I can find a store that will activate a sim with a floor model S10 and then let me swap the sim into my Mi 9
Straight talk (ATT sim) lte without issue. no programming necessary , I have the global model though

Where did you guys buy the China version from?
US mobile white SIM from starter kit (T-Mobile) works well with LTE on Chinese model of Mi 9. Black one (Verizon) technically works, registers in the network and enables data, but Verizon refuses the IMEI as non-certified brand of the phone. Trick with activation on the iphone first and switching to xiaomi did not work, service gets cut off, when trying to make a call, it keeps dropping. AT&T based: Cricket and Straight Talk work just fine too.

Thanks for the info.
I was wondering about Verizon, since it support some CDMA bands and support 2 out of 3 of the LTE bands they use (doesnt support B13). Unfortunately I never tried it myself since half the coverage near me uses the band this phone doesnt support on Verizon.
I went and got my ATT account updated to an old Nexus 6 IMEI number and it got LTE on the N6. I then took the sim and put it in my Mi 9 and now the Mi 9 has LTE. So for anyone just getting this phone, you must have an IMEI on your account that is recognized as an LTE phone. If you try to add the IMEI of the Mi9 it is not recognized by ATT and wont provision LTE.
IMEI spoofing does not work with Verizon, as they simply ban the device. They call it “non certified”. Bands are seem ok.

I been purchasing from liaow. Never ran across a issue with them
I've been having the same issue, with a recently-bought (last week arrived) Mi 9 Global on AT&T postpaid. LTE showed up and worked fine day one, now network speeds are dropped down to 3.5G speeds. Anyone else have success with getting LTE on a fresh SIM?

So I got a Chinese edition phone with band 2, 4, 5, 12, and 17 to fully support both TMobile and ATT network. The Global edition was missing band 17 for ATT so I didnt want to go that route. Been going back and forth with ATT a bit for the past few days since my device came in. The phone shows up and an "unknown device" on their network when we tried adding the IEMI. It will get UMTS (2g) and HSPA+ (3Gish/4G), but will not connect to any LTE or GSM. The phone supports GSM fine, so its strange that it wont do normal cellular connection over that, it will only do cellular over UMTS. The device wont detect as an LTE device and so the sim wont activate LTE on it.
Anyone else with ATT have this issue? And were you able to resolve it somehow?
Or those with TMobile in the US, are you able to activate the phone fine and get full coverage and LTE working?
I messed around with the connection settings in the *#*#4636#*#* menu. Only the "LTE/TD-SCDMA/UMTS" and "LTE/TD-SCDMA/WCDMA" will work properly at all. Both options give me UMTS for cellular, and HSPA+ for data. Of the 4 APNs that ATT uses, only the "ATT Phone" will work at all. The standard LTE APN "NXTGENPHONE" will leave the phone with no data or cellular service. This is related to the phone not being detected as an LTE device and the SIM not activating as such.

I got the Chinese version and I'm in the US. And I I have the straight talk T-Mobile sim and everything works like it is suppose to expect my internet. It says its 4g but it is very very slow. Any ideas?
