Hey, Just the thread i needed !!!
Off the research so far,
Droid 4(XT894) is a CDMA Device whose ESN is attached/programmed to a verizon mobile number ... right ?
Within the US this device does not support/accomodate a GSM SIM card ... right ?
While outside US, Verizon number works on international roaming.
meaning Calls and text(does internaltional verizon data work too) work on this phone while travelling internationally just fine ... right ?
While travelling outside US, one could load a Local GSM SIM card and this will enable this phone to work like just any other GSM phone ... right ?
Here's where my question's lie ...
When a GSM SIM card is loaded outside US what happens to the pre-programmed Verizon Number which was working on roaming ?
Does the verizon number work alongside the international GSM SIM card ?
Do calls to the Verizon Roaming number and the local GSM SIM number both work together ?
If so ... can one use Verizon Roaming number for calls, and the local GSM SIM for internet data ? ... simultaneously ?
Will it be the same like a dual-sim phone where both numbers work simultaneously ?
;
;
;
Is it true that this phone supports even a CDMA SIM Card on its SIM slot ?
thanks for reading and any info is greatly appreciated.

Really all verizon uses is the sim card, I have pulled my sim card out and used it with my XT908, XT894, and XT907 without ever contacting verizon about the change, and call, text, LTE all work fine.
The XT894 can only be connected to either cdma or gms not both.
It will not work with other USA carriers
If using outside of the USA, gms will work but suggest installing the gms patch, for improved compatibility.

You will need to root, and install Safestrap, before installing the patch.

thanks for the quick reply @sd_shadow ...
So that confirms that the SIM slot reads both GSM and CDMA SIM modules.
I still have a feeling that Verizon (i could be wrong, hence the question) programs these phones to work based on their ESN No. else why would people on ebay sell phones with 'CLEAN ESN' ... If a verizon CDMA SIM can work out of this phone why does one need a clean ESN, I thought clean ESN's are used to program CDMA mobile nos. through them !
Anybody here running a Droid 4 (XT894) without a verizon CDMA SIM just fine ?
OR
Droid 4 (XT894) runs only through a Verizon CDMA SIM unlike its non SIM based older cousins ?

ESN is old technology, and hasn't been used for some time.
What are ESN, MEID, and IMEI (device identifiers)?
Every device has a MEID and/or a IMEI which is used along with the sim.
Verizon will blacklist a device if it is reported stolen or you don't pay your bill.
Lots of people are using the Droid 4 outside of the USA, but only with GSM/3g
LTE only works with Verizon.
The Droid 4 will not work without a sim card, GSM nor LTE/CDMA.

@sd_shadow ... appreciate the quick response and the clarification.
I read somewhere that Droid 4 can be registered with other CDMA operators outside USA only with an ESN Number, hence my question ... if that is another way to program a device with a mobile number to run without a CDMA SIM.
With regard to LTE ... If any country has a LTE network running on a frequency(700 MHz) similar to that of Verizon, then may be this phone's LTE might work ?
Probably my original question would seem relevant to a ... GSM-SIM-SLOT-modded ... Motorola Photon Q LTE (XT897) ... as that is a device which works as a programmed phone and there is no SIM Card Slot for CDMA SIM either (or has it got one ?) !!!
Any ways thanks for the information !!!

The Droid 4 can be manually programmed via DFS CDMA Tool, but only through the stock boot process and ROM. You would have to adapt the process a bit for a foreign carrier, of course, and getting the needed info might be slightly harder.
After being manually programmed, and if Mobile Networks > Subscription Type is set to NV-only, it can be used just like an older 3g-only phone: data works, SMS/MMS works, etc. You DO need a SIM card installed in LP, though, or it constantly complains about the SIM missing and stock SMS won't send messages. Certain KK ROMS (SlimKat for instance) don't need a SIM card installed at all. Whether the SIM is old or new, active or not, etc shouldn't matter.
Assuming you get through all that, you'd also need a carrier who is willing to add your IMEI to the network to "activate" the phone. As far as I know, no Verizon-based MVNOs do this after the beginning of this year (PagePlus was probably the last, they finally stopped after Verizon started double-charging for each activation), but I'd imagine carriers outside of the US would have less of a problem with it. Again, getting the needed information to program by hand might be difficult, and the phone can't be automatically programmed OTA.
Best way I can think of to get said information would be to get a natively 3G phone, have it programmed OTA, then access it with DFS or the like to see what the programming is like. Copy the parameters to the Droid, have service transferred to its IMEI, bam, in theory you have 3g service.
While there might be other carriers using the 700mhz LTE band, depending on how standardized LTE is or isn't, they might not be using it in the exact same way as Verizon. It's certainly possible that it would work perfectly fine, but I wouldn't bet money on it.

thanks @Septfox ...
So if One was using SLIMCAT ROM and somehow programmed the phone to say a CDMA operator(the way you've described), say in India(from where i am) ... then without a CDMA SIM card this phone's Call, SMS & Data(3G) should work just fine ?
During such an instance if i load a GSM SIM of another operator what would be the situation ?
I am just looking at using CDMA for Call & SMS(would be good too if Data worked) ... And from my GSM SIM i would like to use only the Data !
So what are the chances of that ?

In theory, yes. As long as the channels match up, CDMA service is pretty standard as far as I know. And to be as clear as possible: you can use any ROM, if you have an LTE SIM card installed. The SIM doesn't need to be active, as it isn't actually used if the phone is manually programmed, it is simply there to make the phone stop complaining about a missing SIM.
To reiterate though, this is all in theory. As @sd_shadow said, to use 3G CDMA outside of the US, you might want to find a phone that does it natively. The Droid 4 was intended for 4G LTE/voice over CDMA in the US, and GSM internationally. Trying to get it working on a non-Verizon CDMA carrier should be done as a curiosity, not out of expectation that it will work.
As for non-Verizon carriers in the US, there are at least a couple; Boost and Sprint come to mind. Verizon is the primary CDMA operator here, most other carriers claiming CDMA service are actually MVNOs (Mobile Virtual Network Operator) who "rent" capacity on Verizon's network and resell it to customers as prepaid packages. Verizon MVNOs will refuse to activate the Droid 4 for 3G-only service, as its IMEI immediately gives it away as a 4G LTE device. Boost and Sprint probably won't care, so long as the phone operates on the same channels, but they also won't offer any assistance in programming a phone if it can't be done OTA.
Wherever you are, you would probably have an easier time finding a GSM carrier, since all of the needed information is on the SIM card. There are a lot more "ifs" and "maybes" when it comes to CDMA when it can't be automatically programmed, unfortunately. That said, if you have a particular carrier in mind, it may be worth looking around the internet to see if anyone else has tried to program this phone or the RAZR (which apparently has a similar radio); it might turn out they've already gathered all the necessary information, and it's a matter of entering it all into your phone. Finding information for Sprint and Boost should be easy; carriers outside the US might be a bit more difficult.
Lastly, it's worth pointing out that the Photon Q is a physically similar CDMA phone with technically superior specs, already on the Sprint network. It lacks a SIM slot, though, without some delicate modifications to the mainboard and case, so it can't be as readily moved to GSM service. It's also not as well-supported here (at least, the last I checked) as the Droid 4, so its ROMs might still have some outstanding bugs.
Also like sd_shadow, you can't use CDMA and GSM service at the same time. Stock and most AOSP-based ROMS are configured for Verizon 4G/CDMA service by default, and have to be patched to change over to GSM; this necessarily disables some CDMA functionality. To undo the patch, you have to reflash the ROM (or replace the files that the patch changes, if you backed them up).

So, as my backup GSM phone just crapped out (Unlocked Samsung 'Blackjack') I start pondering of D3 potential. Do people think theres a way to custom edit some files like the radio.img to enable the harnessing of US GSM bands while simultaneously preserving access to big reds 3g airwaves. I ask this because I have to use my overseas sim card once every couple months so it doesnt get deactivated. How much time could it require?
Thanks
Eric
Check over in the dev area. They've been unlocked and used on T-Mobile/AT&T already! There's a guide as to how to do it.
yes but that requires the crippling of the cdma radio.
Anyone know if it's possible?
I'm running my d3 on at&t u.s. right now, I don't have a foreign SIM to test with or I would test that method.

Is there a way to put my current phone service on a Verizon DROID 4? My phone has no SIM chip, the DROID does. Is there a way to do this? Please someone point me in the right direction, my current phone is so beat and I'd love to learn this but haven't heard anyone talk about this. WHy do some phones have SIM chips and others don't?

The SIM is there for LTE&GSM service, the Droid4 is an LTE&GSM enabled phone.
Verizon's network isn't GSM though, it is a CDMA phone, so they use the SIM slot for LTE only. You will need to update some CDMA settings, your best bet is to take your phone into a Verizon shop and have them set it up for you!

Not true. The CDMA settings are in the SIM cards too for 4G phones on Verizon. I switch my SIM card between different 4G phones I have and it knows who I am when making calls, texting, 3G and 4G.
But you right, you have to go to Verizon so they can provision a SIM card for your account. Its free and pretty simple to do. After that, no more ESN/MEID swaps!

So the Sprint GS4 has a removable sim like the HTC One.
Frequencies and Data Type LTE: Band 25 (1900MHz); CDMA 1x/EVDO Rev A, Tri-band: 800/850/1900 MHz; HSPA+/UMTS Dual-band: 1900/2100 MHz; GSM Quad-band: 850/900/1800/1900 MHz

Looks like Tmobile is out but AT&T should be ok (no LTE obviously)?

Sure. With the removable sim you can pop in any international sim you want and use their cheap prepaid rates while travelling.
Another benefit may be to unlock the sim and use at&t prepaid when your sprint service sucks.
Those not in the US may not realize CDMA carriers have not had many GSM radios/sims in the past.

This is the GS4 general section correct? Until they break up the forum to carrier this is the right place as far as I know.
i already have a sprint international sim but don't use it often.. nice knowing i can pop it into the S4 and use it overseas if i have to instead of the ancient motorola v600 i have.
this is not to be confused with a sim, it is a uicc just like verizon/metropcs/uscc/cricket use
Although I'm not planning on going out of country it is good to know our phones will be "world" phones.

I would assume you could get a cheap disposable pre-paid in your area of travel, insert and profit? Someone correct me if I'm wrong here but that's the way I would see it.
let me reiterate, this is not a sim. it is a uicc. someone already tried to stick a gsm sim in and set to global and got an invalid sim. this does not mean it isnt a global device, just could be that it is locked permanently, locked to sprint and have to get an unlock code from sprint to unlock it, or would never work in the first place.
regardless it isnt looking great ATM, once more people have teh device and can actually mess with the hidden settings then more info can be found out. but as of now i would not buy this phone based on the premise of using it on gsm, sprint has a pretty piss poor track record with unlocking gsm stuff (ask any photon 4g/photon q owner)

It's probably SIM locked like the HTC One is. Therefore, you should be able to call Sprint and have them provide you the unlock code, which they normally will if you meet certain criteria. There are several folks on the HTC One forum who have reported they have done so succefully. All this said though, I still expect for the phone not to be able to be GSM operable with US carriers like all Sprint GSM phones have been in the past.
Also, I am pretty sure the original Photon 4G (WiMax) already came SIM unlocked out of the box.

it came unlocked but was limited, the iphone 4s had to be unlocked shortly after launch, the photon q had an embedded sim.

Pin and Puk codes have nothing to do with SIM locking though. Only the carrier and manufacturer have that.

What do you mean by "limited"? (Besides disabling inside-US usage, which has always been the case for all Sprint GSM phones; a known policy which I wouldn't expect Sprint to ever change.)

that is what i am referring to, and no i dont expect them to change either. realistically, a sprint customer doesnt need to use those carriers. but it would be nice to be able to use a photon q on tmobile without having to shred it to bits and solder in a new sim..

Even if you could shred it to bits it would do you no good because Sprint blocks reception of US GSM signals at the radio level. Personally, now that Sprint is back to using removable SIMs, I don't really have that big of an issue with what Sprint is doing with respect to blocking US GSM, as long as they enable international usage with any SIM and, if they SIM lock the device, don't give you too much of a hard time to obtain the unlock code from them so that you can use the device with other carriers if you are outside the US (rather than forcing you to pay their exorbitant international roaming rates).
It should be noted though that in the Sprint S4's case there is actually another related issue where Sprint did something really dumb and annoying which is to disable the UMTS/WCDMA 850 MHz band completely (for use both inside and outside the US) and has done so for apparently no good reason at all. That could cause major issues to folks who wish to use the device in certain places like S. America. However, this is a topic that merits its own separate thread though, which I plan on starting sometime in the next couple weeks after I get more info. on this problem.

So the Sprint GS4 has a removable sim like the HTC One.
Frequencies and Data Type LTE: Band 25 (1900MHz); CDMA 1x/EVDO Rev A, Tri-band: 800/850/1900 MHz; HSPA+/UMTS Dual-band: 1900/2100 MHz; GSM Quad-band: 850/900/1800/1900 MHz

Thoughts? Hoping we may get it unlocked for domestic use as well as international.
Looks like Tmobile is out but AT&T should be ok (no LTE obviously)?

yea, but the big question is can it be unlocked so its not stuck on sprint

Are we 100 percent sure the UMTS/WCDMA 850 MHz band is blocked?
apologies all around, i was wrong. its not a uicc but a full on sim card
im a big enough man to admit when im wrong
I was wondering if it was possible to unlock a Tmobile g2 for use on verizon? Also could i do the same for a ATT G2 for use on verizon?
Thanks yall!

Nope. Verizon uses different technology.... LTE is the ONLY reason Verizon phones use a sim card. You could do the Oppisite though, you can use an Verizon G2 on T-Mobile or AT&T but not the other way around.
It's already factory unlocked.

No the Tmobile version does not have CDMA radio which is what Verizon and Sprint use for 3g data and calls.
The LG G2 Verizon model (vs980) comes fully gsm unlocked on 3g, 1x support.(CMDA unlocked LTE,3G,1x. I believe:good I have seen multiple people have their lg g2 connected to the T-Mobile network no problem.
Someone correct me if my information is incorrect.
Thank you.
No. It's impossible. Not just bc the radio technology is different, (gsm/cdma) Even if the bands were completely compatible, verizon would not allow it on their network. Only verizon certified phones will Work. Meaning they have to be verizon branded

You CAN use GSM networks on the verizon G2, the phone radio fully supports HSPA+. You will need to change it in the hidden cellular settings pane, I just used an app called "Advanced Signal Status" and scrolled down until there was a button called "Additional Info" from there I went to "Phone Information" and you can set the preferred network type. Set it to GSM/UMTS. if you are running on stock, it's Settings > Tethering & network > Mobile networks > System and then select it. You will also need to add the APNs.
Verizon cannot lock down their phones to one network according to the FCC Network Access Regulations.
"(e) Handset locking prohibited. No licensee may disable features on handsets it provides to customers, to the extent such features are compliant with the licensee's standards pursuant to paragraph (b) of this section, nor configure handsets it provides to prohibit use of such handsets on other providers' networks."
Verizon can block certain handsets from being used on their network, but cannot block their branded phones from going on a different network if the phone's hardware supports it.
If it were impossible, how are many people connecting to and using GSM networks on the Verizon G2 (VS980)?!
Even though Verizon is a evil carrier, they cannot prevent this.
Do research before posting.
Thank you,
Stephen

stephen, thanks for such a nice thorough post, but YOU need to reread my post or actually reread the ORIGINAL post as well. the question is , can you take another carriers phone and use it on verizon, not can you take a verizon phone and use it on GSM, we all know you can do that . LOL LOL!! . , YOU CANNOT use gsm phones or any phone what so ever on verizon unless it is a verizon branded phone, again , (like i said in my original post) REGARDLESS if its compatible with their network. thanks for rereading...and have a nice day
oh... and youre right, verizon can not lock down their phones, (again we all know that,) but they can lock down who, and what accesses THEIR network. please do more research before posting "information" lol

I will have to apologize completely for this, I AM SORRY. I had just woken up, and was groggy, but you were right,
I AM TOO FULL OF MYSELF
Have a wonderful day!
This is why I recommend buying the Verizon model. Not only do you get additional radios to use on Verizon or any GSM network, it is unlocked out of the box and has Qi Wireless Charging unlike any of the other variants. Moving from ROM to ROM is no biggie either. I've seen people flashing Tmobile Roms on the Verizon G2.

Hi guys.. Hoping much to get your expert opinion.. I live outside USA and got a Verizon G2 as a gift. When I turned on the phone it asked to select the language which then further proceeds to set up but since it cannot connect to Verizon server , it just keeps searching and then routes to emergency calls only.mode.. Tried to insert the local Sim but its not recognizing it.
I have seen you guys talking about having it factory unlocked out of the box but this doesn't .. Please help the brother out
PS. I am a layman so kindly use digestible method.

I think you have to go into your network settings and change your API's to match your network you intend to use. That carrier should supply those if you call them.

It works for me i lived in asia. Cdma and gsm both work. But for cdma i have to inject the number and i also plug the gsm sim card incase there is no signal i can easly switch to gsm provider.

Hi Everyone,
I've been reading the reviews and specs for the MI5 Pro and am considering purchasing one. GSM/CDMA support, 128Gb Storage, etc. sounds great to me.
My plan is to have something with an unlocked BL so I can root, TWRP, and AOSP it just the way I want it.
Before I do how much of a pain will it be to getting working on Verizon's 4G/LTE networks? If I understand what I am reading correctly it supports all the frequency bands on Big Red. Any thoughts? Comments and suggestions are requested on this.
Thanks in Advance
I should also add this is not for the BYOD (Bring Your Own Device) program. I have a monthly plan and am up for a new device but don't want what they offer.
I highly doubt you'll be able to get it to work on Verizon. Even unlocking GSM bands is a pain.

VZW is CDMA. The specs say it supports all the needed bands I just don't know if they are "active" out of the box.

I don't specifically know about verizon, but our local CDMA carriers do work with the Mi5.
Cdma carriers the us only allows approved devices.
No hope.

You can be the guniea pig and try it out but your chances of getting it to work on Verizon are slim to none.

The more I research this the more dim the results look. It seems that the problem with bringing it to a CDMA network is lack of 4G functionality. Definitely a deal breaker for sure......
Verizon only allows approved devices on their network (read: their branded devices). So there's pretty much no chance of your Mi5 (an unapproved, semi-compatible, and untested device as far as they are concerned) getting on the network, as your MEID needs to be in their system for you to connect to their network.
Stick with an actual GSM carrier.

I knew that was how they were in the past but I thought maybe they loosened up on it. They now have a Bring Your Own Device program. Still doesn't get past getting 4G working flawlessly on CDMA.
I need to look deeper at GSM carriers in the US. Coverage in my area is important for work.
I just saw you message and it is a bit late, but I have the Mi5 and use it on Verizon. It is only 3G on that. I can also use both my Verizon Sim card and my AT&T sim at the same time and have two carriers with two different numbers on the same phone. I had to do nothing to get it to work on Verizon other than pop in the sim card. I hope this helps.
Thanks DFSPCC, I was wondering the same thing and having it listed to work with VZN in the US on willmyphonework.net up to 3G speeds, which is fine by me. Considering the low price at the moment for the Mi5, I think is a great option.
Never to late
I'm considering on getting this phone... 5.7 inch with OK specs to work with Verizon only thing is you said 3g but that's OK its just to play and test hopefully I can root it... Don't knkw if they have any Roms for it..... Ive been HTC for over 10 yrs and they have let me down been waiting for a 5.7 or bigger... The max was nice but bad specs realy slow so.... I was going to do the s8 plus but now I see the U12 coming soon. But i don't know if Verizon will carry it... They don't carry the U11 don't know why.... What do you think? And thanks again for your time and help god bless....
