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.

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).

[Q] Unlocking SPH-L710 4.1.2 for use outside of the US

hey I'm new to the forums and rooting and I'm trying to unlock my Sprint SPH-L710 so that I can use it on a carrier outside of the states. If this thread has already been started sorry for the redundant post, if not can someone post how to unlock a SPH-L710 4.1.2 from Sprint so that I can use it in Canada please.

The Sprint S3 is a CDMA device, and not GSM. There is nothing to unlock for use in Canada. It doesn't accept a SIM card (though there is one embedded for LTE purposes in the U.S).

ok interesting, I was told that I could use it on a network here in Canada that also uses CDMA as long as it was unlocked but maybe they thought that I had the GSM version.

[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.

Unfortunately, can't be done as Verizon uses CDMA and ATT uses GSM. Means radios are completely different.

As stated above, Verizon and att use two entirely different networks. The radio hardware is different. Unless the droid dna is a gsm phone that should not be possible.

That phone is also GSM capable. At that point it's all a matter of the APN settings. It can not be done with the S3 on any carrier (swapping from CDMA to GSM)

I think you can get the Verizon S3 to work on AT&T (calls/text/edge data). I know you can do that on T-Mobile. But you won't be able to get the AT&T S3 to work on Verizon for two reasons;
1) The radio would need to be hacked to enable the CDMA radio, and the information needed to hack the radio is not available. The US variants all received the same radio chip, just some of the frequencies are turned off. For instance, the AT&T S3 wasn't able to get the t-mobile AWS band working until the guy working for t-mobile released some radio files. The AT&T/T-Mo S3s have the CDMA radio, but it's not enabled
2) Verizon won't allow the phone on the network, as the IMEI is not registered on their network. This is probably the most important reason. You would need to spoof the IMEI from another verizon phone, which is not something that can be discussed here.
You are better off switching with someone who has a Verizon S3, that wants an AT&T S3.

It will work with T-Mobile because it's a GSM network. The radio can't be hacked. It's a limitation of the hardware itself. It's 2 completely different pieces of hardware.

The sim card on Verizon phones is ONLY used to access Verizon's LTE, without that simcard you'd have regular 4G only on a Verizon phone. That sim card/or phones acts in no way possible as GSM accessible.
So no it will NEVER work regardless of what you do.
And don't fall for ads on the internet about any Verizon,Sprint, or any CDMA phone to work on GSM networks.

This is not entirely true for all Verizon phones. The DNA, S4, Note 2, LG G2 (among others) are sim-unlocked out of the box, and will work with AT&T/T-Mobile (the note 2 requires some hacking in order to add the APN settings). Also, as I recall, if I took the sim card out of my GNex and DNA, I did not have service. It would only allow for emergency calls. No talk/text/2G/3G.
For the Galaxy Nexus, the phone is 100% guaranteed to not work on any GSM network.

Read the first sentence
"Only to get Verizon's LTE"
Unlocked phones work "globally"
Which means you'd get Voice and EDGE/3G at the most from other GSM networks, given you've provided the correct APNs. Locked phones, which carry that sim card for Verizon's LTE ONLY. Either way only a few phones will work. The rest are useless.

No. They use the same hardware. Msm8960. It should support GSM CDMA WCDMA LTE and Td-scdma. Almost all the network. It's mostly because of the lock of the radio/nv.

Remember, the op is asking if he can use an at&t galaxy s3 on Verizon. It's not going to work.

IT WORKS

i can verify that i an running AT&T straight talk service on my sch-i535 (Verizon Galaxy s3)

I have had success using a Verizon sg3 mother board on att's network although I was only able to get 2g. What I did was rooted phone, ran region unlock app, next I let the phone sit for a day, then a did a factory reset from the phones menu not custom recovery. Then when going through the set up wizard it prompted me to insert sim card then it said it was not an approved sim and gave options to continue or finish, selected finish, said complete and about 3-5 mins after booting up I got signal bars and phone was working. Although the hardware used are different these are dual band phones.

T-Mobile and Locked Bootloaders

Is it True that Samsung Galaxy phones for T-Mobile do not have Locked Bootloaders??? So if true, I can use a T-Mobile Unlocked Galaxy on AT&T network? But would not get updates for it while AT&T sim card is in it and using AT&T? CORRECT???

There are 2 "locks" that you seem to have confused.
1) T-Mobile phones are SIM locked when purchased from T-Mobile. That is they can only use T-Mobile SIMs. Once they are paid for, T-Mobile will give you a code to unlock the SIM lock. You could then use it with AT&T, but their 4G LTE systems are slightly different, so you may not get the same speeds when using the AT&T towers.
2) The T-Mobile S4 SGH-M919 sold does not have a locked bootloader, which means you can root it, and also install custom Recoveries.
There are several threads about using this phone with an AT&T SIM. Google/Search is your friend.
Rob

^^^great explanation.
Though, I do wonder if unlocked bootloaders are common with other T-Mobile phones as well or if the S4 is just an exception.

Unless you include Sony.
Sony devices do still have thier bootloaders locked with no way to unlock them.
