HELLO people
Well, here at Mexico we have Iusacell a cdma/lte carrier. I was aking them if they support a double subscription mode like verizone does. Because my phone can skip between both signals (gsm and cdma).
They tell me that what thet can do is to give me sim card, and they enter sim card serial and phone serial into system, and that way couldwork. They claim they have a sony phone that does that jump (gsm-cdma-gsm) and it is the way they configure it.
Will this work ok D3 and D4?

As far as I know, only the USA is using LTE on the 800mhz band block. This is the compatible frequencies of the droid 4 for LTE. The GSM should work though, I'm not sure what frequencies you guys use in mexico though.

Don't forget that the Droid 4 also has 3G CDMA which might be compatible with frequencies in Mexico, not just LTE.

I know Droid4 is 3G CDMA and 3g GSM compatible. But here Iusacell claims to use LTE.
However, that is not my question. My question is if the schema that iusacell offers me to register bot SIM and Phone number will let Droid4 jump between CDMA/GSM?
I have the Motorola Droid Bionic, can i flash it to work on Sprint network? they're both CDMA so i figured it would be a possibility.

Simple answer, yes. As far as the difficulty level in doing so, I am unaware. It is technically possible, as the CDMA bands seem to be friendly with each other, as in using them on one carrier is the same as using them on another as long as you can program it. The LTE 700 radio has been unlocked as well to be able to be used on GSM networks. I am currently searching for a simplified solution.
I have an Ekit SIM card that we have used successfully for international calling when we're traveling (we're based in the US). I have used it in my old HTC Touch Pro 2 (one of Verizon's 'world phones') - put in the card, then the pin, and it connects to available GSM signals. Testing it out at my home in NC, it quickly connects to TMobile.
I have SIM unlocked my wife's Motorola Droid 3, another Verizon 'world phone' - I install the SIM, boot it up, type in the PIN which is accepted, but when it tries to connect, I get the following:
Network Error
No GSM/UMTS networks were found. Would you like to switch to the Global mode?
Is there something different about the signal bands between these 2 phones, such that my Touch Pro 2 has no problem connecting to TMobile GSM here in the US, while the Droid 3 won't? Now that I write this, I do kind of remember reading somewhere that the Droid 3 is not compatible with US GSM bands, so that might explain it.
The bigger question is will it still work outside the US? Specifically, we're going to Tanzania, by way of Amsterdam, and would like to have the option of calling home, or receiving calls from home, with my wife's Droid 3 (I retired my Touch Pro 2, and am now using the Samsung Galaxy Nexus).
We want to travel as light as possible, so would prefer not to bring an extra phone if the Droid 3 will in fact work with this SIM card when overseas.
Thanks!
Being that you have a U.S. branded DROID 3, you need to do some modifications to get it to work on GSM carriers.

Thanks for the reply - interesting link!
In my case, I don't need it work on GSM carriers in the U.S. - I just want to be confident it will work when I'm overseas.
I did a little more checking, and confirmed that (without the steps in your link) the Droid 3 would not work with US GSM carriers, so I'm reasonably confident I'll be okay when I get overseas.
Thanks again.

You just need the unlock code, either by contacting Verizon with an account in good standing (or a friend with one) or purchasing one by a well known code dealer (I've heard several people recommend unlock4moto). Although you did mention you already unlocked it. Just putting that there for drifters reading the thread.
After unlock, the D3 should work flawless with foreign GSM carriers, you just need to make sure to input the APNs for data if they are not provided already on the SIM. Otherwise, the phone will not connect to US GSM networks (such as T-Mobile, which is 2g only, D3 lacks the 1700MHz band for Tmo 3g), it would require a flash of the XT883 radio + build.prop... Which is actually quite quick, painless, and simple once you do it a couple times. I keep a copy of both build.props in my /system folder.
For informational purposes; the D3 supports these bands to compare to carriers;
UMTS on 850Mhz, 1900Mhz, and 2100Mhz. (Supports HSPA+ 14.4Mbps)
GSM/EDGE on 850Mhz, 900Mhz, 1800Mhz, and 1900MHz.
CDMA on 800Mhz and 1900Mhz
Stock radio gets you; Verizon in the US, unlocked for any foreign GSM network
XT883 radio gets you; No CDMA (Might work with RUIM card, SIM equiv for foreign CDMA networks/4g LTE networks) GSM anywhere, including the US.

Yes, I've already unlocked the SIM - got that through Verizon with no difficulty. Appreciate the other details!
Based on what I've read, and the posts here, I'll be happy to leave my Touch Pro 2 home, and the D3 should do what I need to on my trip. I actually don't need/want data on my phone out there - just wanted another option to call home when WiFi isn't available (I'll be using Skype when it is).
Thanks for the replies - told me what I needed to know!

Hi All,
I bought a Verizon Droid Turbo more than a year ago in USA at full price (unlocked), used it there and now I am in India.
I am using a local telecom operator 'Tata Docomo CDMA', but the mobile data is not working on it. I had a debug session with one of the engineers. He said the APN username has [email protected] and due to this it is failing authentication and hence data not working. The APN username was set to <mobilenumber>@omh.ttsl.in . This username was not getting reflected.
Phone is not rooted.
Have tried the following combinations.
1. Problem CDMA sim + Droid Turbo= No Data
2. other number CDMA sim + Droid Turbo= Data working, no APN settings done. This sim is old one.
3. Reset to default for APN + add new APN on Droid Turbo= no Data
4. Problem CDMA sim + HTC one M7 = Data working, no APN settings done
I am clueless at this point.
Any help would be greatly appreciated.
Thanks
Bump, any suggestions?
Well, I just did some research and your carrier is shutting down their CDMA service.
https://en.wikipedia.org/wiki/Tata_DoCoMo#CDMA_shutdown
CDMA shutdown
Tata Docomo is at present shutting down the CDMA network. It started calling its subscribers to migrate to GSM and confirmed CDMA network would not be available after 1st July 2016 in various telecom circle areas across India.

It's already started in some regions:
Following RCOM�s decision to shut down its CDMA network across the country as part of 4G upgrade, TATA Docomo has now announced that it will shutdown its CDMA network in Andhra Pradesh circle. As per update from Docomo customer care, Tata Docomo CDMA services will not be available in the circle from 30-06-2016.

So, you're not going to be able to use CDMA anyway in a few months, even if where you live still has it. Are you sure your region still has it?

OK, here's two possible reasons.
1) your CDMA carrier uses different frequencies than what your Verizon phone has.
What frequencies does your carrier use? Here's what the Droid Turbo has.

If true, that's not what the Droid Turbo has.
That quote above may not be factually correct. I really can't find much information about specific CDMA bands your carrier uses.
OR
2) Possibly your CDMA bands are locked to Verizon? Verizon's LTE bands are unlocked on their phones but I can't find confirmation they unlocked their CDMA portion on their phones... If not, it CAN be unlocked but it just may not be unlocked right now.
This may or may not be an answer, but how did you obtain your phone? Here's why I'm asking...
Before Verizon launched LTE network, they were notorious for locking their CDMA phones to their network. When they went to LTE, they started doing that also. Our U.S. communications agency, called the FCC, told Verizon if they wanted any more LTE spectrum (in future airwaves auctions) they would have to unlock their LTE phones. Verizon agreed. This happened in 2012.
So, if you stick in an LTE sim card from another carrier, you will get LTE signal. All of Verizon's recent phones, like the 2014 Droid Turbo XT1254, also have HSPA bands -- which would also be unlocked (because Verizon doesn't use HSPA, but it's there).
Not many carriers use CDMA. Here's my point. I can find no confirmation Verizon ever agreed to unlock the CDMA on their phones. That was NOT part of the agreement, only LTE. (They may unlock it also, I just can't find confirmations.) Right now, your CDMA bands may still only work if connected to Verizon.
Now, a lot of dealers who sell Droid Turbos (or any Verizon phone) in other countries know how to "unlock" the phones so they will work on other networks.
IF my hypothesis is correct and IF your phone was obtained from a non-dealer, say a private sale, it may not be unlocked for CDMA use on other carriers. You would need to get it network unlocked. There are internet based services who do this kind of work as well as 3rd party dealers.

Additional questions:
HTC one M7 ? What carrier is that phone affiliated with? Did you buy it used somewhere or is it your carrier's phone? Or at least an "India" carrier phone? What CDMA bands does it have?
Oh, lot of questions, but I have answers for all.

Yes, they are shutting down the business. But the region where I belong to Andhra Pradesh/Telangana, they would be shutting down next year mid 2017. This is not in the news as such, but got it from the internal guys. This region has the one of maximum subscribers so they decided it to keep it going longer.

I have multiple Verizon devices (Moto Droid Turbo, Moto Droid Razr, Samsung Galaxy Stellar) using the same network operator Tata Docomo CDMA. Although I didnt lookup the exact frequencies, but I can assure you that they work on this operator and have same frequency as Verizon.

I bought the handset Moto Droid Turbo at full price in USA. Moreover, I have another sim (~4 years) from the same operator (Tata Docomo CDMA) which works perfectly fine in Moto Droid Turbo. The calls/data work out of the box, no settings required.
But for this particular sim from the same operator, which I recently received, only calls work, no data.
So let me put it this way.
Tata Docomo CDMA sim 1: Moto Droid Turbo - Calls only
Tata Docomo CDMA sim 2: Moto Droid Turbo - Calls + Data

So the Asian market has comparatively different handsets compared to the Western market. Most of the handsets are not carrier based, they are sold with out any carrier branding to work on any carrier.
This HTC One M7 has dual sim capability and the first slot supports both GSM and CDMA network.

The very bottom is most important. The rest is working through my reasoning and how some of your answers dashed my theories.

We'll come back to this in a minute. I admit I may have glossed over some of this initially but you repeated it and it stuck the second time. Thank you. Repetition does work for me, especially when presented slightly differently. I was more focused on the HTC working and the Droid Turbo not working on your SIM card, and why. I missed that one of your SIM cards works great with the Droid Turbo.

OK, my concern was either they may be using some strange frequency for your CDMA that that Droid Turbo couldn't handle or they may be cutting out CDMA in your area.
I know you have an HTC One M7 that still gets CDMA, but I thought maybe it was an "India" version that could handle unorthodox CDMA frequencies that U.S. phones cannot handle. (Your link to specs of the HTC M7 dashed that theory. It uses 800 MHz for CDMA).
Here in the U.S. for a few years I was a subscriber to regional CDMA/LTE service that used an uncommon frequency for CDMA. All their phones had access to an extra CDMA band that Verizon phones did not have. I thought that might be the same in India...
Or that your carrier was using a mix of "regular" CDMA frequencies with unorthodox and only the uncommon were left running (for now) as they shut down their CDMA system.
It would explain why the HTC would work (because it was perhaps manufactured for India) while the U.S. would not work.
I specifically bought three Moto XT1225 (known as the Moto Turbo XT1225 in India) from other countries because they have all the U.S. AT&T LTE bands (2, 3, 4, 5, 7, 17). Whereas the Droid Turbo XT1254/U.S. Moto Maxx XT1250 only have 2, 3, 4, 7, 13. Doesn't have LTE bands 5 & 17. And AT&T doesn't use CDMA. For people using the Droid Turbo on AT&T, they will only get LTE in areas with LTE bands 2 & 4, and will have to drop down to HSPA in areas where AT&T uses LTE bands 5 and 17. LTE 17 is used a LOT by AT&T in Atlanta where i work.
I thought something similar was happening to you, if certain CDMA bands were being discontinued in your area, but you have no other frequencies (like HSPA) to drop down to.
However, since one of your two SIM cards (both same carrier) works just fine with the Droid Turbo, then that's a dead end.

Yes, but I asked how/where you bought the Droid Turbo, for a reason. You answered, but this was my theory...
When I bought my three XT1225, one was already "unlocked" Motorola factory model from Mexico. Two of them however were Claro carrier models from Puerto Rico. They are locked to Claro, would not normally work on other carriers like AT&T -- but the eBay dealers unlocked them before shipping them to me. They have to be unlocked by special code before they can be used on other carriers. I thought perhaps the CDMA portion of the Droid Turbo was that way. I know the LTE is unlocked, and the HSPA, but Verizon has a history of locking CDMA to their network.
an unlock code for these Verizon devices: try 000000 or 123456 to use these phones on a different carrier.

Again, that's now a dead end since one of your two SIM cards works just fine with this Droid Turbo.

Does this new SIM -- the one that works with the HTC, but not the Droid Turbo -- also work well with your Moto Droid Razr, Samsung Galaxy Stellar? Is it just the Droid Turbo that has issues with the new SIM?
I assume the old SIM card, the one that works well for the Droid Turbo, also works well with your Moto Droid Razr, Samsung Galaxy Stellar?
I wondering if your carrier has changed something in their SIM cards, if the OLD one works fine for all phones, but the new one does not -- especially a U.S. phone?
Try this anyway on your Droid Turbo, can't hurt:

You are correct, the operator has upgraded the sims over the last couple of years, but I cant exactly say what has been changed.
I cross checked with Verizon, they said the device is factory unlocked, so no point in trying the unlock code.
Yup, I am at a dead end.
Although I can set the APN, but that doesnt have any affect on the Data connection. I got it debugged with the operator, he says that some verizon username ([email protected]) comes in APN hence the connection is getting refused or in short authentication failure.

Hmmm.... is your Droid Turbo bootloader unlocked? What if you flashed XT1250 firmware over the XT1254? Firmware including radio. That would wipe out all Verizon references. XT1250 U.S. Moto Maxx and XT1254 Droid Turbo are the exact same device with the same FCC ID. Same radio bands, and everything. Many people have flashed XT1250 over XT1254 and vice versa. As long as your bootloader is unlocked and you don't try to downgrade bootloader versions (i.e. gpt.bin) you should be OK. Even if something goes wrong, with unlocked bootloader you can always just re-flash the Verizon firmware.
People have even done it with locked bootloaders but you have to get everything exactly right. I wouldn't take a chance with a locked bootloader.

I might give it a try it I am willing to go out of comfort zone

With official Verizon update for Moto Droid Turbo, which upgraded to Marshmallow, the issue is resolved.
