I don't think that it needs activation, since you are gonna use it for GSM. You will not be able to use it on CDMA though, needs to be programmed.

Please DO NOT buy unactivated phones... It will NOT have GSM part open yet... My DroidMINI is lying useless due to that and my DroidMAXX is working great (MAXX is like new used one)...

Droid Maxx in India
Here is another update.
Another XDA member got a new Droid Ultra last night. It did not work on GSM and it seems the activation on VZ got through (I don't know how). But when checked with VZ global support, they verified the phone and SIM are not associated with any account.
Anyway, GSM did not work. Then he tried Reliance GSM and it worked for a few minutes for calls and data.
Calls could be made and received. And then, suddenly there was an "invalid SIM" message.
So, who is blocking this? Verizon? or Reliance?
Another source tells me that the IMEI has to be cleared for international use. So VZ has to release this IMEI so that Indian companies can verify it to be genuine and not stolen, or invalid.
Now, the only way to get that done is with some insider contacts in Vodafone, Idea, Airtel or Reliance.

^^^^
I don't think it has anything to do with Indian operators... Everything has to be done from BigRed end, afaik... I don't think Indian telecos are following International database of BadEsn / IMEI...

This is all very strange... I THINK that the bad ESN is just relevant to verizon, and I also THINK that verizon is not involved in this. Or maybe they changed something. Also it is strange that for a while the phone worked and then not. I would call your provider and ask why.
It was clearly said that verizon is blocking only SIM for US carriers before. Also, HOW would they unblock it by registering in their network? If you connect to your local provier, verizon is completely out of the connection process. That would mean, that there is some software/firmware thing in our phones that is blocking it (read try unlock bootloader and flash another rom = last chance)

I traveled to India (Bangalore) a couple months ago. I used an Airtel SIM card while I was there, and it worked great. Of course, my phone had already been activated before I went.

XDA member Harsha has two Droid Ultras. One of them works and the other does not. So he took the IMEI's of both these phones to a local carrier Vodafone to check.
The working phone's IMEI was found in their database when they checked. The other one was not found - reported as invalid or not found.
I checked that one with Motorola after that. Motorola's database has Harsha's name against that IMEI. So, that database has got that entry.

Unlocking bootloader and then flashing which ROM? This will just complicate the matter further, with Moto and Verizon both saying we have no role to play in this. They might not even help in troubleshooting further.
What I understood is that local carrier puts you on the network and in a few minutes, it realizes that the IMEI is not found/ invalid. So you are kicked off. That is why two people were able to use it for some time and then they were out.
I am not sure why data works for some of the guys though. It should not.

Yeah. Activated phones work without problems.

No need for unnecessary speculations... If the phone is NOT activated in Verizon, then its GSM part can NEVER be used anywhere... PERIOD...
Further I checked (here) my working MAXX's IMEI and not working Mini's IMEI too. Both are saying valid...

Well, the IMEI on those overseas sites will show as valid since it is a valid device there.
But if you visit an Idea/ Airtel/ Vodafone store and ask them to check the two IMEI's you will find that the phone which does not work is reported as invalid IMEI.
Harsha has tried this with Vodafone, since he has two phones as well out of which one does not work.
Also, it is not true that if the phone is not activated, then it cannot be used on GSM anywhere. We have several reports on XDA where people have used brand new devices on GSM.

we Got gsm working if any one got gsm working let us updated

GSM now working for most phones
So, Motorola confirmed that an entire block of IMEI numbers was missing from the GSMA database.
While the cause for this is unknown, they were kind enough to escalate this to the GSMA authorities and get the IMEI numbers included.
Now, Indian carriers have synced their database and most carriers are working, but some are still not with some phones.
It is not clear what else is wrong with some of the combinations of phones, SIMs and carriers, but so far out of the five phones which were not working, four of them are working (out of those a couple are not working with one carrier).
Some phones are working with pre-paid carriers only and not post paid.
My phone is employee edition and still not working with Idea cellular.
In fact, after doing a factory reset yesterday, even Reliance CDMA is not working now. Strange.

My droid mini is now working fine with my regular Airtel postpaid nano sim.
Please share which operator Sims are not working.

Droid series - some more missing IMEI blocks I suppose
So, yesterday, another person contacted me stating that he just got two Droid Ultra's (new, never activated) and these are not working on GSM.
With CDMA, the data does not work, but the calls work fine.
Now, I have consolidated a list of phones and the carriers against which they have been tested along with the type of SIM and the type of connection (pre/ post paid) and send this to Motorola.
Perhaps the new range of IMEI's is also missing from the GSMA. But I will get confirmation in a day or two on that part.

Update:
Did a full FXZ install using House of Moto 2.0.
Then, did a four corner activation bypass as per the video here (which is for the older Razr Maxx.
https://www.youtube.com/watch?v=fYcZYZPGO2s
I don't know if that helped or the FXZ or both. After pressing corners first in landscape and in portrait mode, both, several times, I actually was able to skip the screen to some other screen.
After following the remaining prompts, it took around a minute to search for networks. I manually selected Vodafone IN and it took a few retries to register on that network (I have poor indoor coverage).
I tried with my regular service provider SIM and that one showed the network instantly.
No tried to update anything using WiFi so far.

Z3 Dual D6633 SIM compatibility / issues

Hi, I've got a Z3 dual D6633 which I want to use with an EE SIM in the UK. I've tried a cut down microsim and been into the EE shop and tried one of their nano SIMs but both don't work correctly in the phone.
The cut down SIM makes a service phone.android.com or something like that continually crash and doesn't connect to the network.
The one I tried in the shop just doesn't connect to the network.
This is on 23.0.F.1.74 and .82 I noticed in the release notes for .82a fix for Yoga SIMs in Russia but don't know what the problem there was, but wonder if it is linked. All other UK Sims work including 3, Lyca, giffgaff, Vodafone, virgin just not EE. has anyone got an EE one working or had similar problems?
I did notice that an app/widget I use called phono to show network info and signal strength usually shows the IMEI when no SIM inserted or the MSISDN, however with the non-working EE SIM it just shows 00000 - not sure which field it is getting wrong. Oh and yes the SIMs work fine in all other phones I've tried.
I do need to try more tests on factory reset and removing phono etc but so far it looks to be a firmware incompatibility with EE Sims.

OK, so I did a few more tests and got hold of another nano SIM on EE.
So it looks like the 23.0.F.1.74 firmware does not like EE SIMs and the phone application constantly crashes. On the later .82 firmware it works fine. I was mislead a bit by going into an EE store and trying a SIM - they must have given me an un-provisioned SIM to try. I stupidly assumed they would have actually given me a SIM that worked, doh!

I'm experiencing something similar here. I have the D6633, bought in UK, now I am in Brazil and the phone works great except that it won't connect to the 4G/3G/2G/LTE network. I can make calls, send sms normal. But internet only over wi-fi.
I called my operator, they say the phone is configured correctly, I tried my brother's sim card from another operator and the same happens.
So, the phone is clearly unlocked, if not it wouldn't recognize the sim cards at all. But no connection to the internet...
Any suggestions? I already did four factory resets, I recovered the Rom using sony software...

Hello, I have the exact same problem. How did you get the firmware .82/for what country? Is everything working well with it? Really appreciate your guidance.

I had the same problem with the EE sim card, ended up sending the phone back.

Just a thought, but is it definitely a 6633 and not some other variant which perhaps doesn't work in your country/network?

I purchased my D6633 from Saudi Arabia and the 23.0.F.1.82 update came as an OTA notification about a week ago.
If you look in this thread http://forum.xda-developers.com/z3/general/d6633-z3-dual-updated-to-23-0-f-1-82-t2929352/ it mentions that someone thinks the update has only been released for Saudi and Brazil - I assume it is for Europe as well as one of the release notes says a problem with Russian Yota SIMs has been fixed. I think there are also links to the firmware in there although I've not looked that hard as I got the OTA. I guess it might still in my memory - anyone know where Sony stick their OTAs?
Seems to work fine so far - no noticeable difference - well other than EE SIMs now work!

Hmmm, sounds like another issue as with mine the EE SIM caused the phone.apk to constantly crash/restart.
Did the data work OK in the UK?
As you can make calls/SMS I assume you are at least on a 2G network which should still give you (very slooow) data - It does sound more like an APN issue - or something else. I know you said you checked with your operator what their APN settings should be (just my experience with operator customer support lines) - but I would try and have a look yourself - and maybe list your APN settings and operator and someone may spot something.
I have seen a couple of phones / operators where the "APN type" in the APN settings needs specific settings - its down the bottom and often isn't mentioned when people get the settings. For example in my current settings I have "default,hipri,dun,supl" for Virgin mobile in the UK.

For mine, on my networks here in Australia, I can assign 4G LTE to any sim, however, that makes the other sim 2G only (GSM).
The other option is to have both at 3G (WCDMA/HSPA).

If you assign 4g to sim one that work only for 4g or like other phones "LTE(preference)/WCDMA/GSM"
4g not available automatically search 3G if 3G not available automatically search 2G?
Assume second sim is on 2g

Yes, your 4G sim slot will fall back onto 3G and 2G as per expected for most handsets.

Have you managed to root it? I rooted the 23.0.1.f.0.96 firmware for my Z3 D6633, but after a while (half a day) it starts to reboot frequently, and Google Play stops working (can browse apps, but not download them, as the download bar never progresses).
Also, my EE sim seems to work, but the phone still shows it as 'Sim 1 0000000' whereas other sims simply appear as sim 1 and sim 2.
I am wondering if I should just downgrade back to 23.0.F.1.74 and move from EE to Vodafone or 3...

Ah, work forced a BlackBerry (yuck!) on me and I've since sold the D6633.

[Q] Using the verizon variant internationally

Hi,
Just bought today the verizon variant of the galaxy s6, and I need help with a couple of questions:
I'm moving to Europe in the near future, would I still be able to use the phone?
From who do I get software updates? Will I get updates from verizon even if I'm abroad?
Would it be able to flash international firmware on this phone in the future? Are the models fundamentally different from each other or are they just handicapped by firmware?
Thanks in advance

Yes it works internationally, I'm using it on GSM right now and plan to use it in Egypt over the summer. You will get updates but I think verizon needs a verizon sim to check for updates but when one releases you can always check through a computer if you need to. As far as I know verizon one is the bay because it supports CDMA radios and GSM radios and comes pre unlocked while other versions like tmobile only support gsm. That's the only hardware difference, the rest is all software.
Also be careful with your phone! Nor sure where in Europe yuppie going but some classes visited Spain recently and lots of them we're pickpocketed and had something stopen.

920V is different from the international version. It supports very few LTE bands and i'm not sure it supports as many 2g/3g bands as the internation one. you may have voice but you won't have LTE.

Hi,
Didn't u have the same issue with texting?
I bought my s6 from verizon on a trip in the USA, but I live in UK and using 3 network. The only issue is the texting. I spent lot of time to figure out what is the real problem, and it seems like it is sort of prefix problem. If I receive message from someone with new number with +4407 (obviously all of them start) and I reply, message is not going to be sent and I always get a message: " Your text to speech message to 0114407..... has been rejected by recipient phone." I never use text speech btw, and it definitely prefix problem because if I send to 07... only they receive it. I changed all my contacts to 07... but still after that I couldn't reply to messages for a long time just only with the Handcent next sms app. But If I receive a new message from a new number I'll get with +447.. and I need to save it and change the number to 07.. otherwise it will never work. I found some people had the same issue in the past, but there was no final solutions: http://forum.xda-developers.com/showthread.php?t=2106370

[HOW-TO] Fix LTE for International Model Note 3 (USA Carrier)

So something weird has been happening since purchasing my mint conditioned note 3 on Sprint. Every time I was inside my home, my note 3 would lose LTE and stay on 3g. I was looking for answers and not finding a single thing. I came up with a solution myself and here is where the explaining begins. Be careful when purchasing a phone online as some are international phones (which we know). I happened to purchase an n900p note 3 model and it was actually made in China but my signal radios were set to Japan. If you are in the USA and using Sprint then do the following:
-Download from the play store an app called Samsung phone info
-After the install is complete open the app and open the menu on the left side
-Select Secret Codes
-Scroll down to settings and select Launch 0
-Choose Phone Information
-In the upper right hand corner there are 3 dots, choose radio baseband and select USA from Japan
-Enjoy LTE

i am trying to use a n900p (sprint) unlocked phone with a gsm carrier in india.

Are you rooted? Or on the default ROM for your device? The problem could be sprint uses CDMA not GSM, GSM is for devices without sim cards but I think is used on sprint for the sole purpose of emergency calls

But do you still have IMEI and Baseband version?
(look for the Baseband version and IMEI in the Phone INFO app).

the phone is rooted and running close to stock tw 4.4.4 rom.
true that sprint is a cdma carrier. but the n900p has all the gsm basebands which my carrier provides.
also phone has been internationally unlocked using sprint unlocker. (ssu.apk.)

baseband is nk4 and my imei number is shown which starts from 99.
so i think everything is pretty normal here.
i am just concerned about the phone not activating and it refuses to register to any network. i've tried 3 different indian carrier sim cards.

The phone might not be compatible with that specific carrier or you might have to take your sim card to the carrier and have them activate it but who knows.I took mine to Sprint and the guy asked me where I got the phone, I told him online. The problem with me having a Japan radio baseband set as default my LTE signal gets lost when I go in a building but when I'm outside, it picks back up again. If I switch the radio to USA I get 4g but then can't send/receive MMS. After a period of time on the USA baseband, it will completely lose signal and show up a black empty service in my status bar

Not if the sim card isn't working I would contact the carrier and see if they can get your sim card entered properly for service to your device

AT&T APN Settings for UK Version used in US

I have the UK Version, trying to use it in the US on AT&T. If I did my research correctly, the phone can support 3 out of AT&T's 4 lte bands, but I'm only getting the H and H+ icon. I know that in the UK, the 4g icon means lte, but I'm pretty sure that H and H+ mean HSPA and HSPA+, not LTE. Is there anybody in a similar situation that is able to get 4g? And if so, do you mind posting your APN settings, or the steps that you took to enable 4g on the phone?

Mine shows 4G/4G+ (which is LTE).... The only bummer here's that it's super low where I live. I know my previous OP3T got higher service bars but right now I'm fine because I use WiFi 99% of the time. The settings I use are for the ATT PRODATA apn (you could just search for those settings on Google) and the phone also set to 4G preferred under mobile network settings. Hope that helps

Is your IMEI on your AT&T account your XZP one? If so, that's your problem. I went through that already. I had support switch it to my Pixel and instantly got LTE on my XZP.

I wonder why that's the case. My previous phone was an unlocked verizon lg g3, which didn't have all the lte bands on the phone. I'll have to try w a friend's sim or something and see I get lte then. That's the only way I know to test this.

Who knows? I have the G8142 model. Perhaps they weren't a fan of it. I was on AT&T years ago with my OPO and Nexus 5 and had no problems (signed with Nexus 5 IMEI). I switched to Fi then until a few weeks ago when I switched back.
I spent days trying different APNs and toggling data connections. I couldn't get anything. I even tried putting the sim back in Pixel and couldn't get LTE. I found a thread from years ago on AT&T's website about a guy having the same issue. I did the chat support on their website and asked they guy to switch my IMEI and gave him my Pixel one. I restarted both phones and got LTE and both of them almost immediately after he did it (while still in chat).

I just found my old at&t g3. If I ask them to change the imei on the account to this one, will they do it, or should I play dumb and just act like the imei is wrong and ask them to check it?

I told the chat dude that I couldn't get LTE and I was pretty sure it was because my IMEI wasn't an official AT&T phone. He said that was probably why and I asked if he could switch the IMEI for me and he said yes, then I gave him the new one.
You could always say something along the lines of your phone breaking and just need to switch to an older phone for the time being, then ask if they can change the IMEI.

I just had them switch it back to my G3, you were right in that they thought for some reason it was a 2g phone, the rep confirmed that AT&T is now sending data on their end, but I'm still not getting it on my end. Would you mind posting your preferred network type, and apn settings?

Nevermind. The rep called me back and it was fixed. Now getting the 4g and 4g+ symbol on the phone. Thanks for the help

Not a problem. Glad it worked! :good:

Does LTE not show up in the status bar for you? I have the international model as well and LTE often shows above the signal in the status bar. I also still have my Z5P, I factory reset the device and had a different AT&T sim added to my account and put in and there was no connection. One of the reps added APN settings and it started working, but it only shows H,H+,4G, or 4G+ and not LTE. I don't have it with me right now so I can't check the differences between the settings right now.

If you have the G8141, when it displays 4G/4G+, it means you're connected to LTE. This threw me off at first too because I'm not used to seeing that.

I don't think there are differences like that between the two models, I have the G8142 and LTE shows very often above the status bar. It sounds like your APN settings may not have been correct during the provisioning process.

So far from what I'm seeing around here on the forums, the G8142 does actually show LTE whereas the G8141 shows 4G rather than LTE. You can actually verify this by downloading the app Cellmapper which will show you which towers you're connected to, which frequency band you're using and which connection type you're using.
Trust me, I went through this process already because everyone with the UK model (like me) shows 4G and everyone with the Dual SIM shows LTE. Another forum member explained to me that this is because of market differences in the UK being that they don't advertise LTE but rather only 4G (which is actually more accurate with regards to the connection type).

4G and LTE are the same thing internationally. Some regions on Sony firmware call LTE by different names- for example the Nordic firmware calls it 4G while central Europe 1 calls it LTE.

Ya, ignore what I said earlier about the APN settings, I fixed them but LTE is not showing up in my Z5P, it's still only 4G/4G+. I originally thought that I had the Central Europe ROM on the Z5P but I did a factory reset and it seems to be something else based on the default language, but I can't figure out which one it is. Anyway another difference I see between the XZP ROMs is that the US ROM has more signal bars than the one on my XZP, can someone let me know how to find what ROM I have since the build number is the same for each of them it seems?

Sounds like you have the UK ROM. Mine does both of the things you mention. Usually only 2 bars and shows 4G/4G+ when I'm connected to LTE. However, the signal bars thing may actually be due to poor signal because in some areas around where I live, I will actually get full bars of 4G/4G+

If the UK ROM does not show LTE it's not the one that I have. I was saying LTE shows up on my XZP but not my Z5P, I think my Z5P was from Taiwan but I'm not sure, I bought it on Amazon. My wife has the US XZP and that's the one I was comparing the amount of signal bars with. I would still like to know how to actually view what region firmware is installed though, I haven't found a good answer anywhere yet.
