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.

yes, it will work for talk and text but maybe not for LTE.

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 have an unlocked Galaxy S4 active i9295 and I cannot get the 4G or the LTE working since I do not have even the option I only have WCDMA/GSM I travel around the world with this phone and now I am in Ireland on 3 and still I am getting H+ showing and not LTE or 4G. Is there a way to activate 4G or is there any special 4G sims ?
I would check your APN settings, seeing how you are unlocked, the proper APN may not be installed to match your Sim, check with your carrier, to make sure they are 4G and LTE capable and get their settings.

Try ShowServiceMode. It should help to unlock LTE band. It worked for me here in Poland, because local career's LTE was locked by my Russian firmware. But using this program I can only switch between phone calls (GSM/3G) and LTE, they cannot work simultaneously.
Thank you guys. One major thing is that why I can even see the option in the settings? If anyone else has some information please help out.
Thanks
I'm leaving for NO, LA tomorrow. I need my phone to be reliable. My issue is the phone drops signal often (T-Mobile US Prepaid) but it says it still has full bars and 3G/H+. SMS, MMS, internet and sometimes even calling all fail until I reboot my phone. I am on OmniRom Kitkat. This also happen on stock ICS and JB. Would switching APN settings from T-Mobile US (epc.tmobile.com) help at all? At least for calls and texts? I have 5 options. Simple(APN simple) StraightTalk T-Mobile(APN wap.tracfone) T-Mobile US(APN epc.tmobile.com)
T-Mobile US LTE(APN fast.t-mobile.com) and T-Mobile US LTE IPv6(APN fast.t-mobile.com). Would any of these make a difference? Or can I force roam on ATT and would that help? I bought a new sim but that didn't fix the problem. HELP Please!

This phone is missing the AWS/1700 band support for T-Mobile. If you are on prepaid, then you should try getting AT&T compatible MVNO.

The 1700 should only effect data. And even that isn't entirely true because my area is refarmed to 1900
No. T-Mobile 3G supports both voice and data.
T-Mobile 3G (HSPA)
•With 3G, theoretical maximum download of 14 Mbps.
•Our 3G network operates on the 1700 MHz and 2100 MHz frequencies. You'll need a phone that supports 1700 MHz and 2100 MHz to connect to our 3G network.
•On our 3G network, you can use voice and data services simultaneously.
UMTS/WCDMA is technically capable of both voice and data.
