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.

Hey guys,
xda still going strong. nice to see.
need some help though.
i bought a note 8(yes in 2020) for some reason(side device) and i got stuck with a problem right away.
i noticed that TDD LTE bands(band 34,38,39,40,41) are all missing from my device.
i am having an exynos varient (n950f)
i was monitoring my network from past 2 days and 3ca was working fine. i was connected to 3,5 and band 40 all together.
i wanted better reception so went in network selection mode and selected band 5 preffered. i dialed *#0011# to check my ca status and i was still transmitting on all 3 bands with speeds well over 100mbps.
after some time my speeds died and i no longer see band 40 in *#0011# menu and i have tried restarting device and what not but still cant connect to band 40.
i am pretty sure TDD LTE bands including band 40 was missing from band selection menu earlier too but things were just fine. not i am stuck with a expensive device that fails badly.
please help.
on some inspection i observed that my phones is continously doing 2ca even when using no major data on band 3 and 5.
basic is stuck on band 3 and s1 on band 5. me changing to whatever setting in band selection in hiddennetworksetting dont affect it.
tried selecting bands that my operator dont even support. not in preffered mode but as the only hard selection. makes no diffrence. network signals shuts for a second and i am back on band 3 and 5 combo
