Sprint version: does not disable GSM?

The Sprint version is being advertised as an international phone, and comes with a Sprint SIM card pre-installed, and what appears to be a security strap, making it difficult to remove.
Before traveling internationally, you can call Sprint ahead of time to have them active their SIM card, and for the low low price of $1.99/minute, you can use overseas GSM networks to make phone calls, and in many cases, data access.
Of course I'd like to buy a pay-as-you-go SIM card and install that for much more reasonable rates while overseas, but I'm not sure if it's as simple as plugging in a different SIM card.
I had read that the Rogers version of the phone required...something to active the SIM slot, and even then seemed not to work for data via 3G.
Anybody else have the Sprint version? Played with GSM yet?
I'm a little apprehensive to start tearing into it to remove their SIM card just yet...

The GSM is 2G only, no 3G.

Well my buddy has a AT&T sim card that i put in my TP2 but it did not work. I switch the phone to GSM only but it did not pick up a network. I also put that sprint sim on his phone but it had no network either. According to the manual its lock from going to a gsm network on the USA.

Hopefully a custom ROM can unlock the ability to use GSM networks in the United States!

good to know.
I read in the manual that it was not usable on US GSM networks too, but I assumed that was because they never intended for you to remove the Sprint SIM card, so of course the Sprint SIM card wouldn't work domestically.
So it seems the Sprint phone can be unlocked for GSM just like the Telus phones, but I haven't read of any success getting GSM 3G to work w/ an unlock code.

What about EDGE?

Check the specs, if it said gsm 850,1900 it should be able to use with in the US. Just have to sim unlock it first in order to use.

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.

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] HELP! Can I switch the AT&T S3 to Verizon?

I have Verizon, a Motorola Razr (Not MAXX) and it is crapping out on me, running slow, not sending picture messages etc.
My boyfriend has a trading post type store and he bought a brand new Galaxy S3 but it's through AT&T. When I put my SIM card in the S3 it asked for a SIM Pin for unlocking.
I have experience rooting a Nook Tablet so with some directions I'll probably be able to do it, I just don't know where to even start. Do I just unlock the phone or is there a way to switch it over?
Thanks!!

It seems like you just need an unlock code to use it with your old SIM.

Try taking a look at this thread and see if you can get an unlock code from AT&T.

So I called AT&T and they gave me the unlock code. I used it and it said unlocking the mobile network was successful. I tried to make a call and it said that only emergency calls were available. I restarted the phone and when making a call it said no mobile network can be found.

Ohhh you are putting a Verizon sim card in it? I don't think that will work since Verizon's network and lte use different technologies than at&t and the sim card is encoded to use the respective technology :X

That would mean you can insert a gsm sim card into the RAZR maxx because it is a world phone. However, the at&t s3 does not support CDMA, which is the network technology that Verizon uses. That's probably why you are getting no mobile network when inserting your Verizon SIM card in the AT&T s3.
Sent from my SGH-I747 using xda premium

The gsm sim that comes in Verizon global phones is there so when you travel out of the country you can use a cdma phone in countries that have a primary backbone that is gsm. In the us your phone uses Verizon's cdma network. If it does not see that network it will then look to the sim card to see if global gsm networks are detected.
To my knowledge this is going to be a no-go. If you have not done so, clean up your sd card, toss a factory data reset at your razor. These android phones are pretty tough.

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.

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.

I received the password from T-Mobile and ofcourse entered it after using an AT&T sim, but I have a company iphone 5 (I HATE IPHONES) i'm trying to see if I can just use the sim card into the Note 3 and call it a day. Anyways any help would be appreciated.
Thank You in advance,

I'm not positive, but if you are able to use it at all, you wont be able to use LTE for sure. The other bands might work fine.

Yes, it can be done, but you will have to give up LTE, that, will not work for you....

sorry, I didn't see this....but you are correct sir.....

Maybe I'm confused. Does the Tmo Note 3 have CDMA radios? I thought not.
Without CDMA and LTE, I'm not sure I see how you'd use a Tmo Note 3 on Verizon.

Yeah, I'm confused also and since when Verizon allows non Verizon phones on it's network and I know Verizon world phones have SIM cards now, but I thought that was just for LTE compatibility and for travel. BTW nobody in US has voice over LTE and I thought LTE was the only mode CDMA and GSM phones actually have in common? I have not used Verizon for at least 3 yrs, but hell things changed a lot if it worked.

I will check on this tonight I have a vzw sim with unlimited still give it a shot

Guys...IIRC you'd need to program a MEID into the NV items that Verizon would accept. Besides, I doubt any T Mobile or ATT phone has CDMA bands. You're not going to just plug a VZW sim in and it works. The SIM is for their 4g LTE and is more of a RUIM than a actual GSM sim. If VZW is anything like sprint, your iccid, meid, and HDR AN (and quite possibly the HA and AAA passwords for certain profiles) need to be correct. Otherwise you're stuck on error 16. That's even IF you can find some way to activate CDMA radios on the device. FWIW, trade your phone for a Verizon one. Done deal, no headache.

The short answer is no. 100% no. Verizon is CDMA and T-Mobile is GSM. Two completely incompatible networks. While Verizon phones also have GSM bands, T-Mobile phones do NOT support CDMA bands. WCDMA vs CDMA are completely different.

I have a T-Mobile galaxy note 3 and my friend had a Sprint galaxy note 3. I took the sim card out of my note 3 and put it in his note 3 and everything started working fine right away. It didn't need an unlock code to use other carries sims, 3g came right on, we made voice calls, and even started using the internet. I took his sim and put it in my note 3 and it needed to an unlock code. So I ended up unlocking my phone and put his sim back in and nothing worked. I showed voice bars but did nothing. Maybe i needed to look up sprint apns or something for it to work. My sim worked fine in his cdma phone. Find a friends phone and try it out first. Hopefully it'll work, i recommend using chainfire's region away app to unlock the phone. It's quick and easy. Plus you can unlock other phones after that with the app.

TOTALLY different than what we're talking about here. The Sprint phone has multiple radio bands (both cdma and gsm) so after a proper unlock (or it may be already unlocked from the factory, not sure) the cdma phone can connect to gsm networks. The T Mobile phone ONLY has gsm bands. Itd be like stuffing a diesel engine into a Miata. It's just not going to work. Yeah you may have been able to insert the Sprint SIM and had signal, an emergency call signal. How would you program the MEID, MDN, MIN, PPP settings and profile settings into the phone should you even be able to connect to sprint towers? You do know there's no update profile or prl option on a t mobile phone too right?
Plain and simple it's not going to work. Some people can't understand that a CDMA SIM card/RUIM isn't like a GSM one...
