Sorry for the noobsih question but is it possible to use the Kaiser on a verizon network?
under the Phone settings it has the option for WCDMA so does this mean I can use it with the Verizon (CDMA) network?
Thanks for help!!!
No, it is not possible. WCDMA (Wideband Code Division Multiple Access)= HSDPA (High Speed Downlink Packet Access), as far as network capabilities are concerned. True CDMA networks, (VZW, Sprint, etc), use EVDO for data transfer.
Any one else loosing LTE data and droping to hspa while on a call. Happening to both my vivid and skyrocket.
Located in Houston, Tx
The reason for this is that, currently, LTE is data-only. Until LTE providers begin to deploy Vo-LTE (Voice over LTE. Basically VoIP, on and LTE network), the only way you will be able to engage the voice stack on your hardware and access data at the same time is if you fall back to UMTS, which has always integrated both services (voice and data) together.
Unlike Verizon lte, art lte uses circuit switch fallback. Can't do hspa and LTE at one time.

THAT SUCKS ATT!!!! I have to talk & use internet on the HDSPA+ network....it seems so slow. Am I the only person this happens to?
It happens to *everyone* because that is the way it works. Notice that every time you make a call the "LTE" tag goes away....and stays gone until you hang up and the phone reselects back.
There will not be any LTE voice until an IMS is up and running...

I know its data only. But dont see why it has to drop off. I have been playing with the build.prop. And it has
#device supports simultaneous 1x voice + LTE
#ro.config.svlte1x=true
So i guess at one point we will have this ability.
This phone only has one radio built in and can't run on both UMTS and LTE at the same time.
I think that setting is referring to a Verizon type LTE device. They have two radios and don't do CSFB like the Vivid/Skyrocket.
Each phone type has it's own pros and cons.
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!

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...
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 just purchased a Verizon-branded VS980, for use with Cityfone (on the Rogers network). I have no problems with voice calls, and my APN settings seem to have automatically populated from my SIM card and look correct. I believe this phone should be able to pick up LTE (700mhz) in my area, and it should support the hspa frequencies.
Anyway, I have rooted and installed cyanogenmod, but that had no effect. I've selected just LTE networks, just HSPA, or just GSM - it connects to HSPA and GSM, but I get data on neither. It shows GSM Disconnects: =======Data======= on the phone info screen
It was like this with the stock rom, and I have rooted and updated the ROM to Cyaonogenmod to see if that would change anything. It made no difference. I am using baseband 24A if that matters.
Can someone tell me what I'm missing?
