After digging through pages of posts about data speed issues and 2G vs. 3G vs. 4G/LTE, can someone with good expertise and knowledge summarize exactly what the phone supports and how it does it? I am seeing conflicting comments, so it is a little confusing. Also, please clarify a comment I recall seeing from at AT&T person that that the Vivid has one radio that switches between LTE and HSPA+ rather than having as separate 3G radio as earlier LTE phones did.
Or point to a good tutorial.
Thanks
I'll see if I can help!
So in order from slowest to fastest, the GSM data technologies are:
2G:
-GSM
-EDGE
3G:
-UMTS
-HSPA
-HSPA+
4G:
-LTE
Most Android phones display these as G, E, 3G, H, & H+ (don't know what stock Android displays for LTE). The Vivid, however, displays G & E, then displays 4G for 3G, H & H+, then 4GLTE for LTE. So no matter what 3G network your on, it'll show 4G (because AT&T thinks H+ counts as 4G), then when you're on an actual 4G network, it'll show 4GLTE.
As for the single radio, yes, that's true. LTE is a GSM based technology, so a single radio can handle all of the above connections. This is different from Verizon, which uses CDMA for its 2G & 3G networks, then switched to LTE for its 4G network, necessitating two different radios: one for CDMA, one for LTE. AT&T, however, has been GSM from 2G on, so one radio can handle everything. This will most likely continue to be the way it works: Verizon (and eventually Sprint) phones will require two radios for two technologies, AT&T/T-Mo phones will only require one.
This leads to one consequence, however, concerning simultaneous data & voice. No LTE network currently implements voice communications, they're purely data. Even when they do implement it, it'll be VoIP based, so it'll just be more data (This will be called VoLTE for Voice over LTE). Therefore, since this isn't implemented yet, phones must revert to the 3G network to make voice calls. On Verizon, since they're two different radios, you can continue to use LTE data while using CDMA for voice. On AT&T, they're the same radio, so dropping down to 3G drops the LTE connection. You can still use simultaneous voice & data (as you can on just about any GSM based network), but you just don't get LTE speeds.
Make sense? Let me know if that helps!
Thanks, BJG222
That's what I wanted to know. I appreciate the info.

Wow thanks, a very helpful summary of so much **** otherwise kinda complicated to figure out.. quick question, under the Network menu, my phone always says HSDPA, not any of the other options you listed above. This means..?
Here is an interesting read...Explains alot, considering I bought my White Vivid in Houston and got amazing speeds on LTE, and can barely stay locked on an LTE signal at home here in the SW burbs of Chicago.

Actually, HSPA+ is also categorized as 4G.

Well, AT&T & T-Mobile claim this, but it's not really true. UMTS = 3G; HSPA was an upgrade to that, call it 3.5G; HSPA+ is an upgrade to HSPA that incorporates higher bandwidth behind the scenes, more of a 3.9G. LTE's actually a new protocol. Technically, by the initial ITU standards, that's not even 4G (LTE-Advanced, the next upgrade to that, is the only one that does), but they've since expanded the definition to include LTE, too.
so we don't get a different symbol for 3G...so how do we know when we are using 3G verses HSPA and HSPA+ ? (other than speed)...
sucks...
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"
Would a verizon sim work in a sprint or T-moblie phone?
I popped in my T-Mobile Sim card and I only get hspa+. I definitely live in a LTE area. Hmm...

im from india i got moto x navy blue customized but device wont get signal dont know whats wrong tried to reset still no luck even getting the signal but instantly disappears and showing emergency only
So, I have a Verizon Moto X and popped in my T-Mobile sim card today and LTE popped up after a few seconds (I live in Boston). My LTE speeds on the internet worked instantly. However, I tried to send a text message and it wouldn't send. Not sure if I need to do anything else to get voice/text to work fine. Any ideas?
if you're on 4.4, you need to manually add APNs

I just popped in the T-Mo sim card again and now text works no issues and calls. Not sure what happened, but oh well.
Now, is there any difference in me using a Verizon Moto X on T-Mobile compared to an AT&T Moto X on T-Mobile. I have both and have been using an AT&T one, but I am just curious.

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
The "specs" of the two phones are:
GSM
Bluetooth® Technology 1
4.0 LE + EDR
Wi-Fi
802.11a/g/b/n/ac (dual band capable), mobile hotspot
Networks
GSM/GPRS/EDGE - UMTS/HSPA + up to 42 Mbps - 4G LTE
2G/2.5G GSM/GPRS/EDGE bands
850/900/1800/1900 MHz
3G UMTS bands
850/900/ AWS/1900/2100 MHz with HSPA+ up to 42 Mbps (B5/B8/B4/B2/B1)
4G LTE bands
700/AWS/1900MHz (B17/B4/B2)
CDMA
Bluetooth® Technology 1
4.0 LE + EDR
Wi-Fi
802.11a/g/b/n/ac (dual band capable), mobile hotspot
Networks
GSM/GPRS/EDGE - UMTS/HSPA + up to 42 Mbps - CDMA/EVDO Rev. A - 4G LTE
2G/2.5G GSM/GPRS/EDGE bands
850/900/1800/1900 MHz
3G UMTS bands
850/900/1900/2100 MHz with HSPA+ up to 42 Mbps (B5/B8/B2/B1)
3G CDMA bands
EVDO Rev. A: 850/1900 MHz (BC0/BC1)
4G LTE bands
750 MHz (B13)
Based on these specs, the difference seems to be in the 4G LTE bands and the CDMA version lacks UMTS B4. Both support GSM.
If I believe the specs, inserting a GSM sim in a CDMA unlocked moto s (developer edition) should give me the same GSM coverage as the GSM phone for voice....and for 3G data, as long as it's not on B4. I should not get any 4G LTE. But I wonder if I should really believe the specs because it almost makes no sense for motorola to have created two different chips/loads for the phones. What would happen if I put the t-mobile or ATT oem load on a CDMA unlocked phone? would it even work? would I really not get LTE since GSM LTE doesn't use 700mhz?
Any thoughts. There doesn't seem to be anyone at motorola who can answer the question...other than looking at the specs....
The reason for the question is I need Verizon in the US (for coverage), but GSM when travelling. I am thinking of getting a net10 sim for travel. Will it work?
(note: I posted a similar question in Q&A a few days ago, but no real response other than pointing to the specs).

as far as i know. the reason I know this, is because before I figured out a way to get my Moto x (standard non dev. edition) to keep my unlmited data, I checked into getting a Blu phone.. they're GSM.. So, you can't use on verizon.. I was looking into net10 and they're GSM. So I don't see why it wouldn't work, however I never went threw with it, so please don't hold it to me.
Putting an AT&T or T-Mobile SIM in the CDMA phone, you probably wouldn't get LTE, as I don't think they share any bands with VZW for LTE. You might get HSPA+ though, depending on what bands are in use around you. You shouldn't have any issues travelling though, as most other countries use the GSM bands supported by the VZW model. So, basically, your only big issue would be getting "4G" service when in the US if you aren't using VZW.

That's pretty much exactly what I want....if I use data at all, it could be 2g speed...my main concern is "in an emergency" phone calls. It looks like just using the phone for GSM calls is only a matter of getting a worldwide sim, or buying a local one which would work in any unlocked GSM capable phone. Now, if I decide to move to a US based GSM carrier, that's a different story where data is important.
I doubt that the hardware in the phones differs at all....just the enablement of the radios/bands. I would bet there is a way to turn on all the GSM bands on a CDMA phone...although it may not be accessible to customers.
I'm going to try a GSM Sim in the phone in the US and see what I can do (or not do).
Thanks.
The hardware is most certainly different. The parts are not installed to do CDMA in a GSM developer edition, and the parts are not installed to add additional bands with a simple firmware hack.
I have verizon for personal, and one work line, and T-Mobile USA as another work line.
When I first got my Developer Edition Moto X for Verizon, and it had 4.2.2, I could put my T-Mobile US SIM in, it received APN settings and worked, at Edge speeds.
After the Kit Kat update, putting my T-Mobile US SIM in I got message that I had an unsupported sim installed which also stayed in the notification pull down, and I had to manually enter the APN settings for T-Mobile to get working voice/data. Again I got Edge speeds. However MMS didn't work but this could have been due to incorrect APN settings.
Just now, I tried and while I got a pop up unsupported SIM message, but it didn't stay in the notification area, and I did get EDGE data, with emails coming in and apps updating from the play store. When I went under Settings - Mobile Network - Access Point names, nothing is filled in. Trying to create and save one, it doesn't appear either. After a few minutes, I got 4G LTE in the notification area. Under Settings -> About Phone -> Status. It shows LTE (without band number). While it shows ICCID (sim card number), it says Unknown under My Phone Number and Min. Data works, Speed test gives me 28Mbps down and 7Mbps up, but also received intermittent "network communication issues" during the upload tests. Dropbox auto uploads fine as I took a picture with the X and my PC notified me of a new dropbox file. While SMS send/receive and voice calls work, MMS send doesn't.
As for the network communication issues... I saw the same thing when using my VZW iPhone 5S which does support more bands than the VZW X, at least comparing Apple and Moto's web sites. I see the iPhone 5S switch between HSPA and LTE when using the T-Mobile SIM.
In my area it appears T-Mobile has re-farmed their 1900Mhz to HSPA

So you picked up t-mobile LTE with a verizon phone using the t-mobile sim??? If the bands are preset as in the specs, that can't happen
Why do you think that happpened?? Perhaps the CDMA version isn't limited to 750mhz/band 13.

Band 4 LTE is also supported on the verizon phone...I don't know if that's why the t-mobile sim picked up lte or not but LTE is 13 and 4 on the verizon variant.

Yes. With the T-Mobile SIM inserted into my VZW X, the "signal indicator" in the Status bar area showed 4GLTE, and under settings -> About Phone -> Status.. Mobile Network Type reported LTE.
It was thought that VZW had enabled LTE Band 4 with the Kit Kat update on the X, like Verizon did with a recent update to the Galaxy S4. I've seen a few posts here, and on other forums asking for confirmation, how can someone tell what LTE band their X is using, and such... but no definate answer.
T-Mobile's LTE is band 4 in some areas.

hey, KidJoe i got a moto x from us cellular but when i insert the sim card the cell says that the sim card is not accept and the cell doesnt get signal, i try to unlock it, but i couldn´t, if you have any solution for me please help me :crying::crying::crying::crying:
I'm running AT&T on a Verizon Developer Edition Moto X. I have good coverage (better than my old Nokia 520) and I get HSPA+ everywhere I go. I'm perfectly fine without LTE since I can still run anything and stream stuff with current speeds. A big plus is I can always switch to Verizon or other CDMAs if I want to.

I'm planning on getting a Meizu Mx4 Pro to play around with but it only supports the 1900mhz band for 3G. I am on T-mobile and only the refarmed areas use the 1900mhz band. Is there a way to test with my Nexus 6 via some app or settings whether my area is using the 1900mhz band? I also read somewhere that if you get T-mobile LTE you are in a refarmed area as the 1700mhz AWS band is being used for LTE instead of 3G and the 1900mhz has been refarmed there for 3G instead, although I am taking the statement with a grain of salt for now.
Search for app called LTE discovery

I think that will tell you what frequency you are on, but not allow you to set a specific frequency. To my knowledge there is no way to do that on the Nexus 6 yet. Could be wrong?
The data service menu is missing on this phone.
You can get into the Field Test Settings, but I highly recommend not jacking with anything....I went in there for a look see, and when I backed out I was somehow in GSM mode and could NOT get back to CDMA until I did a complete nuke and repave of the Google Factory images to get back the CDMA network.
YMMV...but be warned

I believe op wanted to see what bands his phone/provider is using. LTE discovery shows what bands you are connected to.

If multiple bands are available in an area, LTE Discovery will not show you the additional bands, only the one you are using. You'd need to use a service screen to manually set your phone to a specific band, which is not possible currently. Maybe OP can chime in with more detail.

I don't think we need further explanation from the op. It seems clear to me that he is trying to see whether his area has been re-farmed to band 2 1900mhz or has been left at the usual band 4 1700mhz.
Using LTE discovery will show him what band he is connected to on his phone. If it will be band 4, than his new phone he is trying to get will not have LTE. Although sometimes both bands are available so in that case he would have to have the ability to switch.
Switching bands is possible through phone info screen accessible using an activity launcher of some sort. Once you're in phone info , hit menu and select radio band. But I don't think that's what he initially was looking for.

Perhaps, but there is no known phone accessible screen found on the Nexus 6 that allows band selection. Some have used this to determine whether certain bands are starting to be rolled out in various areas.
Edit: I'll qualify that the menu exists but does not allow a selection of all LTE bands. I can only select US, 6 or 7 on my phone.

thank you for your reply, but I think 4636 is not for field test, info inside is too less.

please all not this warning，never use 4636 three dots options menu to select anything it is dangerous to make you lost all signals... Can can search my post in other thread how to write nv6828 value to control LTE bands.
Another side, for OP, to view LTE bands, LTE discovery 3.19 support the real hidden field test menu in as LTE Engineering beta menu. Keyword in below post: @201504

Is there anyway to force LTE band change between bands 13 and 4? At home, I have one bar on band 4, but get 60 dl, and 30 up. However, on band 13 I'll get full bars and get 30 dl, 15 up. I don't use my data at home as I am always on wifi, so this cell standby battery drain is murder. If I reset my data connection it will connect to band 13 initially, but it will then change to band 4. Switching my carrier is not an option as T-Mobile, Sprint, and AT&T get equally crap reception and I'm still under contract with Verizon which ends in October. Maybe then I might think about switching to project fi.
I've seen other threads on disabling certain bands, but those bands are only used by T-Mobile and Sprint, so they are of no use to me. Any ideas?
There is a thread about 4G/LTE.

Further search the play store for 4g switching apps.

I've seen that thread but it doesn't say anything about removing or blocking certain bands. As for the 4g switcher apps they only have he ability to change LTE modes via CDMA or GSM
The last idea, in case you use a Nexus 6.
There is thread with flashable radio's.
Maybe you can find an older radio that doesn't have the bands you don't want.

Yeah, i tried flashing the oldest radio listed and it's still a no go, band 4 still seems to be enabled. :/

No more ideas; think it is not possible to disable band 4, without hacking/patching the radio image.

For now I have my connection as 2g whenever I'm on wifi so that should fix the cell standby for now.

I have the same because here in the Netherlands we have the so called 4G. But when I am home (inside) there is bad connection. Phone calls are disconnected frequently.
With 2G very good reception at home.
On the road I switch to 4G when I need internet.
I use an app to quickly switch 2G-4G.
It's a rather old app of CurveFish and is in the play store - 2G 3G -
I have exact same problem but problem of speed.
There are 3 lte bands 850mhz,1800mhz and 2300 mhz.
2300 mhz has highest speed which i want my redmi note 3 to run on only but in my home it only switches between 850 mhz and 1800 mhz.
Searched a lot but not able to find any guide which allows to lock the frequency to 2300 mhz band only. The signal bar is also 3-4 on 2300 mhz still it connects to 850 and 1800 mhz most of the time unless i am in open area outside house then it switches to 2300mhz band.
Use QXDM

Hi - not sure if this is still a topic of interest, but you can use QXDM software to achieve this - you just need to change NV line 6828 to be "4096" decimal value. On the Nexus 6, this is a fairly easy process as you just need to boot to bootloader and select "BP Tools" as your boot-up option and then the phone will be in diagnostic mode to connect to a PC. There's info out there on XDA with more detail, but as long as you can successfully install the Motorola/Qualcomm drivers you can fairly easily restrict LTE bands to whatever combination you'd like.
Be aware - some say this is a risky operation but I've not found that to be the case. But there is a chance of messing up your device if you're not careful.
Take a look at the "NV Calculator" app in the Play Store for additional info on determining decimal values for the LTE bands (you might want to keep band 2, for instance, as Verizon uses that sometimes as well).
Here's more info on this on XDA:

Good luck!
