[Q] Unlocking Verizon Galaxy Nexus to use in India

Dear Friends,
I am currently on Verizon Network and planning to upgrade my phone to Samsung Galaxy Nexus.
The problem is I am leaving to India in a couple of weeks and I will be staying in India for 3 months. During these 3 months I want to use Nexus with an Indian CDMA carrier.
1)My question is - can i use the Nexus with an Indian Carrier? If yes I guess i need to unlock my device.
2)Can someone help me with the information of how to unlock the Galaxy Nexus. It would be wonderful if someone can guide me with this.
3)If I unlock the phone will I have any problem using my phone with Verizon when I return to US after 3 months?
Really appreciate your help folks

Does india have any cdma carriers? I thought not.

Well that's not true. It is possible, but not plausible. It requires you to completely re-flash the phone to a different carrier's network, and then have the carrier accept a device with an ESN not in their system, which at best is a long-shot combination.
So, it could work, but it probably won't. And it isn't really worth the hassle.

I was under the same impression.
OP, you should pick up a GSM phone for your travels and save yourself the trouble. Leave your Nexus in a safe place at home with the battery left at about 65% charge and the phone off

thank you very much guys for your replies
there is cdma network in india- Reliance Communications

Just trade it for a gsm one

To be clear - Verizon stores even the CDMA subscriber information on the SIM for LTE phones. So if there is a provider in India that uses CDMA SIM cards (rare, but I know they use them in China) you might be able to get this working.
Or you could get a GSM/HSPA phone to use on your trip

Can S3 i747m be modified to use wind mobile?

I am asking if there is a way to make my galaxy s3 i747m useable with wind mobile. Im asking because I remeber that with the Galaxy s2x from telus and I believe rogers you could flash a t-mobile rom and be able to us it on the wind network. I am wondering if anyone has tried this? and what happened.

It sounds doable. If the phone is compatible as is, you may just need to unlock it to get it to work. You may need to try some different modems though.

There is some guy on kijiji that does it for 20 bucks. Yet I have no clue what he actually does lol

Wind uses a the same bands as T-mobile but I believe the LTE is not compatible.

Simple answer Yes but it's very annoying to do.
The device itself 100% supports WIND's Network to it's fullest BUT the SGH-1747m has the bands required Specifically the 1700Mhz disabled in the NV RAM

One you follow that and reboot you will be on Wind's Network... but at least for me every time it reboots I lost access and the NV RAM resets...
What I want to know is there a ROM out there or a way to permanently rewrite the NV RAM so I never have to do this
Samsung is putting responsibility for this 'disabled feature' on the Telecom companies saying it is up to their discretion on what bands they allow. Yet bell is saying that it's up to Samsung one which bands are allowed as Bell does not do any modifications to the NV RAM. Whose telling the truth who knows.... Samsung did hint that it is possible to put permanently enable the baseband (but I would have to speak to bell) Now the funny thing is if I give Samsung the IMEI of my device (which was purchased at a Bell location) Samsung is making a statement that my SGH-i747m is NOT a registered Canadian Galaxy S3... and it MUST be an international S3.... Yet bell has it as it was originally their's and Sold by them and originally activated on their network.
I don't know why but I feel like the SGH-i747m's have some hidden backdoor deals with them has anyone tried to install Wind or T-Mobile ROMS from the T999L to the SGH-i747m and if so was it successful? or is there a Custom ROM that will work?

Just a *bump* to this, if there is any way of not having to plug into a laptop to reflash the NV to re enable functionality with wind will someone please share? I've read of some people having scripts that run in busybox or other similar type areas
Can anyone please share with me said script and walk me through the necessary means of implementing it correctly so my girlfriend stops whining at me every time her phone dies demanding I fix it, even though I've offered to show her how to click the mouse twice and do it her self.

Hi,
Is there a way yet to make the 747M fully operational with Wind Mobile? Seems like SOMEONE should be able to figure this out for us.
In your guys' opinion, if I flashed a ROM for the T-Mobile device, whats the worst that could happen? Soft brick or hard brick?
Would flashing a T999 modem be enough?

No Wind network after restarting my galaxy s3 (i747)
Hi, have you yet figured out how to permanently rewrite the NV ram on a galaxy i747 so that the phone recognizes the Wind network even after the reboot? Thanks in advance.

I haven't. I ended up getting an S5 through wind.

[Q] Help with Verizon Nexus converted to Prepaid Please?!?

Hey guys I am going to try and make this quick and please forgive me I am new to the Nexus. I have been all over this forum and others e.g. XDA, Android Central etc. I have gotten a lot of different info. about how to switch my Verizon Nexus to Prepaid. However I just bought this phone at my bosses pawn shop w/out the SIM card and the guy who sold the phone said it did have service @ one time. In device info the network is unknown, Mobile Network is unknown:0, no phone number, service stat. out of service, MIN: unknown, but does have the MEID & IMEI numbers. I know no SIM card has a lot to do with this info. Verizon will not unlock it for me so I was wondering what I needed to do to be able to unlock this bad boy. I have root and JBSourcery flashed and loving it I might add. Do I just need to get the SIM card so when I use the # and number keys to unlock it the phone will not tell me "mobile network not available" Or is there another way that someone would be willing to help me with please. I will keep reading to see what I can find but any info would be greatly appreciated! Thanks guys and I look forward to hearing some ideas.

Are u trying to go to a gsm network? Is so u can't. Technically u can't go to no other network. CDMA device are ment to stay on the original network. And if u are trying to go t a gsm network you are waisting your time. Only reason the Verizon nexus has a sim card is for 4g lte. Cell service only works with CDMA.

Right I know that from what I have been reading. I talked to TMobile and they said the phone is compatible with them and they offer the SIM card as well. I was going to go go Verizon today and get the SIM card and try to get the phones info In their system. That way I can USD the dial pad and try to unlock it and use it on their prepaid plan if I have to. I am not picky as far as what company's prepaid I want to use really I just don't want a contract.

you cannot use the verizon galaxy nexus on a tmobile network
CDMA is not GSM.
there is a sim slot on the vzw nexus, but it is for LTE only. voice still uses CDMA.

I know that after reading a little more into it. I got the SIM card and now it is picking up verizon network. So really I am SOL with this phone unless I get a contract is that correct? Forgive my lack of knowledge of CDMA etc. I am working on trying to get there by reading more and more about it.

[Q] Flash T-Mobile Rom on AT&T M8??

I have an AT&T M8 which I unlocked, rooted and s-off'd while under AT&T contract. I then decided to switch to T-Mobile and give this device to my 11-year old son. What I'd like to know/understand is whether I can flash some of the T-Mobile Roms I see in this forum on the AT&T M8 and it work with T-Mobile network? Or do I still need to flash the AT&T Roms?
Thanks in advance for any help advice!
Johnny

SIM unlocked would allow you to use it on stock AT&T too if you choose to. Also everything seems to be interchangeable unless noted. I would go for Rom with T-Mobile's Wi-Fi calling, which is amazing btw for those who get sorry service.

You should be able to flash either T-mobile or AT&T (Even roms in the international section, I would recommend InsertCoin) roms without any issues. Eleven and has a M8? Damn, i'm jealous lol.

Thanks for the information to the both ^^^^^^^^ of you! I appreciate it. Yes , he is 11 years old, but a good respectful kid and does well in school. With that I'm okay with giving him nice things. If that should change, then Daddy gets the M8 back!!! LOL

Somewhat related question... If I u were to use an AT&T model on T-Mobile, would everything work correctly, 3g/4g? Comparing the frequency bands online, the AT&T model is missing the 1700 band that the T-Mobile version has. Does that mean the phone doesn't have the hardware components to connect to it? Or is it capable of connecting, just that AT&T doesn't use that band? I'm asking because I want to pickup a used m8, but the T-Mobile version is going for around $100 more than all the other carrier's versions... Could I just SIM unlock an AT&T version and be set, or will some things not work?

That's a good question and hoping someone will have the answer. In the meantime I was able to SIM unlock my son's ATT M8 and install a TMobile SIM using stock ATT rom. So far everything has worked and the 4G symbol does appear in the task bar, although I'm not sure if that really means he's getting 4G. I did have to manually enter the APN settings so he could get mobile data when not connected to wifi.

Tmobile apn settings
Would you mind posting the apn settings that allowed your sons phone to work on 4g and send mms? Its the main reason I'm looking into flashing a Rom and would save me a lot of trouble as I have spent quite a bit of time searching for one that works on my phone and none seem to do the trick.

In need of a lil guidance?

Ok so I need some advice. I was finally able to root my Galaxy S6 recently with Odin/CF-AutoRoot. Now i've got a few questions before I go any farther. The main reason I wanted to root my phone was in hopes to edit my APN's and get my data working. This galaxy is on Marshmallow, the Sprint/Boost Mobile model. I bought it off ebay, when i first got it I took it to AT&T to get service on it. They got my talk/text working but not data because there was no APN options under Settings/mobile networks/etc. That option was not there. I'm hoping if I flash a rom that will restore my missing APN options.
-I need someone to recommend me a rom. I'm looking for a stable rom, preferable debloated too. I just want the phone to function as it normally should and have the apn options back.
-Also, do I need to install a custom kernal too?

This is the forum for Sprint Galaxy S6. Did you buy the Sprint model or the AT&T model.
From what I understand, they are different.
Sprint is on CDMA network and AT&T is GSM, and the two are not compatible.

It sounds to me like you want to use the Sprint S6 on AT&Ts network. Should be possible. However, I believe it needs to be unlocked first in order to use the GSM bands. This may be one of the issues.
Secondly, I recommend doing everything yourself as there aren't many ROMs available for the Sprint S6, so tweaking everything is something you personally will have to do to make it work on AT&T.
Thirdly, why did you get a Sprint model if you wanted to use it on AT&T? I recommend talking to sprint to help you. Custom kernel has nothing to do with carriers, so using the one you have now will be fine.
IMHO: You should have done your research first. Honestly if you wanted to use it strictly for AT&T then you should have bought an AT&T variant, all your headaches and issues wouldn't exist lol. That being said, what you want is 100% feasible, but not by the average Joe. It requires some tinkering and know how and knowing how to navigate around the device.

Just an FYI: You are right, but you're not fully right. lol
Sprint and Verizon CDMA phones normally have GSM capabilities for overseas business travel. In order to unlock the GSM bands, you must get the device unlocked, or tell and pay sprint that you are using it overseas. International Unlocking allows for overseas use, Domestic unlocking allows for USA GSM Carrier use. My phone is International and Domestically unlocked thanks to a very kind and generous xda member.
However, a GSM phone will not work on CDMA networks, just cause they lack the hardware. There really isn't a niche for it so they don't make them.
