Unlock Verizon Nexus for T-Mobile?

So I'm thinking of buying a Verizon Galaxy Nexus.
I know it has a sim tray so i'm wondering if it can be unlocked for T-Mobile.
Any help would be appreciated.

Why wouldn't you buy the GSM version?

It wont work. Different technologies.

Because that would make sense.

Yea, It's just that the guy told me it has a sim tray so i figured i would post here to find out.
Anyone know where I can get the GSM version?
I don't want to pay $500 but ...
Thanks all

Sim tray maybe but the vzw one is cdma and the GSM one is...well..GSM.
Different technologies! Not compatible.

I have the Verizon phone and yes it does have a SIM card but it uses different radios. Verizon uses CDMA/LTE and T-Mobile uses GSM so you can put whatever SIM card you want in there but since it uses different radios it won't physically be able to talk to T-Mobile (or any GSM carrier's towers)

btw, what happen if you travel away USA in a country without CDMA?.
At least, the CDMA iPhone have a simcard tray but it's locked until your operator wants.

Starting with Verizon's 4G LTE phones they all require SIM cards. They were also used in 3G global phones (my old blackberry and droid pro had them) but the CDMA Galaxy Nexus isn't global so you'd just SOL.

well.
nope. it won't work cause it's not CDMA...

@[email protected] can't believe people are asking this question. The phone has been out for over 3 months now.

Besides, the SIM card slot is specifically for LTE... as in, the SIM card is an LTE SIM card. LTE, not HSPA+.
I can only think, because the AT&T (HSPA+) model would be more prolific among sellers, that you'll have a better time finding a better price than a Verizon (LTE) one.

Then you have no service. Grab a cheap GSM phone and pre-paid SIM.

Try the yellow or the sky blue Galaxy Nexus. Those ones will work on both Verizon and T-Mobile.

Thats odd cause I have done it before

Back when verizon did both GSM and CDMA I had a verizon phone that I got to work on tmobile. I think it might have been a windows phone, honestly it was a while ago. I had to pay for a network unlock code and patch a radio or something....anyway, just wanted to say that it is in fact possible. My phone did brick in about two months, but that might have been from getting it wet...anyway...Good luck!

Total non sequitur. The phone in question must have been an old "world phone". The Verizon Galaxy Nexus never had any GSM radio whatsoever.
Also you bumped a 2 year old thread.

For the CDMA GNex you would need either a CDMA or neutral carrier/MVNO (such as StraightTalk, Tracfone, etc.). I have a CDMA ex-VZW GNex (now running Unlegacy-Android 7.1) that I am taking to Tracfone (replacing a Tracfone feature phone) because Tracfone uses a mix of carrier towers (depending on location, either T-Mobile or VZW). My current feature phone uses T-Mobile towers - because I am bringing a CDMA phone under BYOP, I have to ask the carrier (Tracfone, in this case) to create a custom SIM Kit for the brought phone, and thus have to communicate the IMEI and MEID of the incoming phone (this information is in the phone under Settings). Yes - this also applies to lifeline feature phones supplied by Tracfone/Safelink (if Safelink supplied the phone, Tracfone is your MVNO). If you want a GSM version of the Galaxy Nexus, you would want the maguro (the Galaxy Nexus in AT&T Mobility or T-Mobile guise); because GSM is more popular overseas, they tend to get exported compared to CDMA or W-CDMA (Verizon or Sprint, respectively).

Free unlock method.

Edit: this method works for everyone it seems. SOME HAVE REPORTED SLOWER T-MOBILE DATA SPEEDS AFTER APLLYING THIS UNLOCK. This has only been reported a few times and it seems like flukes. I however, nor the OP in the linked thread are responsible for wjat YOU chose to do to your device. You have been warned.

It got a signal. But could not pick up carrier or anything just had signal and said searching in notification bar.
But verizon is CDMA so it did not supprise me.

I see that the LTE radio bands are in there, no surprise there. But I also see WCDMA radio bands too. Does that mean that our Galaxy Note 2 have WCDMA radio too? Or is this just an firmware that Samsung uses across all Galaxy Note 2 devices?

I need to try this I have a at&t sim card.

I think we have CDMA also....not that it does much for us as verizon and sprint require the imei to be loaded into their systems.
WCDMA != CDMA by the way. WCDMA is 3G/4G GSM (aka UMTS)
CDMA is a competitor to GSM. It is used by mainly North American and Japanese/Chinese cell phone companies.
I know Verizon and Sprint in the US and AU in Japan use CDMA. Most of the world uses GSM.

All though thinking about it while we may have the CDMA radio, assuming it is the same chip as the GSM and LTE radio then they may have just not sokdered the connections. Seen that before with FM radios built into the bluetooth chip on the Atrix 4G

Which of the bands are our 4G?
Love learning.

Our 4G is UMTS band 4 (1700/2100) same as our 3G. We dont have LTE yet so no *true* 4G

Sweet.
Thank you.

No problems. This kinda stuff is my hobby. Maybe some day I can get a job at a cell phone company as a technician or something.

I can confirm this works, but I could not get data. I got signal and a carrier name with both an AT&T sim and a Straight Talk (AT&T) sim. It would not load APNs, and I don't have the APN for regular AT&T so I tried with the Straight Talk, put in their APN and still got no data. Neither sim is active currently. It did allow me to call 611 on both sims.

If neither sim is active then I dont think it will allow data. Not sure though.

[Q] Verizon HTC One AT&T Sim

Hi,
I purchased Verizon HTC One from craigslist it was mentioned that it is pre-unlocked phone. I have used T-Mobile sim and it is working however when I tried AT&T sim in it that didn't work. It shows at top that network is AT&T but I am unable to make or receive calls. I was able to use data on AT&T's edge network ( though my sim is LTE). I know that both T-Mobile and AT&T are GSM networks and this phone is CDMA/GSM. Does anybody else using AT&T sim on Verizon HTC One? Do I have to change some kind of settings??
Regards,

Hello,
I have the same Verizon phone and I'm using T-mobile network, but I can't get data started. What APN settings did you use? If
you could please help I would greatly appreciate it.
Thanx,

You will only get edge because Verizon blocked some of the bands that you would need for hspa speeds.

You will have to change settings to gsm/umts as att uses. Settings>mobile data> preferred network. Also Google att 3g apn settings and edit son. You won't get lte but I don't see why you shouldn't get 3g.

Weird because I have a straight talk att and tmobile SIM card with correct apn's set and I only get edge. I know tmobile reformed my area to the 1900 band too. If I pop those SIM cards in my droid DNA I can pick up HSPA speeds with the same apn settings.

That is weird. I would assume if gsm/umts is an option that HTC would have also included the correct bands but nothing surprises me these days.

I think it has only the 1900 and 800 band. Not the 850, which you also need for 3g. Or Verizon blocked those bands despite the phone being factory unlocked.

There's an app called "LTE On/Off", not sure if can download from play store, but included with certain Roms. It allows you to pick different bands. You can select HSPCA/GSM etc. Maybe this will help with other networks??

I'm not sure. On android central I have a thread there about the Verizon one. A person there says he tried it on straight talk with an att SIM and got hspa speeds. I tried both an att and tmobile SIM card in my Verizon one and only got edge with both apn settings. And tmobile rolled out the new bands where I live too. At the time my one was not rooted so I didn't have that app.

could you flash a new radio? Seems like that might help.. and if the hardware is the same and you get the bootloader unlocked, root the device, and achieve s-off could you re-flash firmware, radios, hboot and rom could it potentially operate as a modified at&t (or other gsm) htc one? sorry if this is completely wrong I'm not a firmware guy.. I know basics of rom's and installations that's about it just throwing an idea out there...

Not sure, but you could unlock your cid setting it to all 1's and flash a gsm edition Rom or ruu, flash radios too. Not sure weather it would work or not depending on the Verizon model hardware but all that stuff you can do.
Turns out the guy on android central was wrong, he was also getting edge data but didn't know it.

Are any of you who are trying to use the phone on AT&T running a custom rom, e.g. Cyanogenmod or Santod's Global Edition?

My one max works on at&t fine once you add the apn settings for at&t.

The Verizon one does not have the same frequiences unlocked that require you to have 3g. The DNA has pretty much similar radio frequiences and gets hspa but the HTC one has those bands locked so you only get edge, even with apn settings.

Great. It's usage like this that was a big contributor toward the unlimited data plans going away. Thanks. This is why we can't have nice things.
Back on topic, I'm curious as well if flashing new radios would do the trick.

They would have to be fully compatible and I'm not sure they would be. Maybe possible but I have not tried. Mainly one reason why they stopped selling the DNA.

So the consensus here is that you cant do any better than Edge service when using AT&T SIM in a VZW HTC One?
See, I just swapped my Note 3 AT&T for this phone, and Id like to be able to use data. I use AT&T prepaid but my Note was always able to pickup HSPA and LTE

Have any of you ever tried doing a factory reset from hboot? That will clear out all of the network settings from verizon, and force the phone to be reprogramed from the sim.

I have, with TikTak Google Plus Edition 2.0, I'm still only getting EDGE data (same as with stock) I have tried using a gsm rom, radio, and RUU. The phone wouldn't start with the different radio flash, the RUU would just boot cycle, and the rom would always fail (status 7, 6, 4).
I have spend about 20 hours on this flashing separate roms, radios and pretty much anything i can find

Tmobile S4, Verizon sim

Has anyone accomplished this? Running a Verizon sim in a unlocked Tmobile S4?

i am curious about this as well. i dont think the lte bands are the same though

Verizon is LTE 18. Not worried about that too much. I believe 3g will be all it will get

While a Verizon S4 will work with T-Mobile, I don't think a Verizon S4 will work with T-Mobile. Unless you can somehow enable CDMA radios, which technically don't exist in the gsm variants.

All S4's are actually gsm, including Sprint and Verizon. Both are unlock able and able to use on other carriers, so CDMA isn't really necessary

Yes I know many Sprint and Verizon smartphones are world phones, but Verizon still uses CDMA. So wouldn't you will still need a CDMA capable device if you plan to use it with Verizon? If it was the other way around, that's a different story

Yeah but that's why I was telling you.... if a Verizon S4 is gsm and not CDMA, why wouldn't a gsm work on Verizon if the same phone is gsm?
It's probably completely possible. Device wise.... the big problem would be getting Verizon to allow it on the network if it did

Well, i can't unlock the damn thing anyways. Tried 3 times to avail.
Just as soon as I Odin back the NH7 modem i loose the unlock. Very weird.

that's because it has both gsm and CDMA radios, while T-Mobile's does not. At least as far as we know. I think the gsm portion is there for when you travel for edge and HSPA connectivity and of course also for the use of LTE. If you insert a gsm sim card into a Verizon 'global' gsm/CDMA device, it will display a message "switching to Global mode," enabling full gsm mode. You still need a CDMA capable phone for activation on their network AFAIK.

I would give it a shot but don't have a different sim card to test

Don't sweat it. Im keeping it.

I tried my unlocked S4 with my girlfriend's Verizon SIM from her S5 and couldn't get it to connect to anything. I tried every different network mode I had available and couldn't get it to see any sort of a signal. I'm pretty sure I also tried to manually search for a network and saw Verizon as an option, but didn't end up getting anything out of it.

Not really. I had my note 3 from sorint running on tmobile. But i only had edge and slow service bad voice calling. This phones hardware bands and software bands arent really meant for it. I had to modify the carrier info in my phone to get on tmobile alone. But ince there sorint didnt work anymore. A domestic sim card unlock isnt as easy as with gsm. With gsm the carrier info is practically just in the sim card. But with sprint CDMA it in the phone. Right now sprint sims are just for the lte and spark network. Not the actual use of the phone. So youre kinda out of luck sorry.

Ita bc the hardware is not made for it. The frequencies arent right. If you go to sprinta website the only phones they have that they can domestically unlock for any gsm are the iphones.
