GSM/CDMA - Global Roaming - Verizon Samsung Galaxy S III

I searched the Verizon Galaxy S3 forums and could find no discussion about the global capabilities of this phone. I had understood at purchase (pre-ordered) that an OTA update would be coming soon to turn on global capabilities. I have seen nothing yet. I have called Verizon, gone to local store (useless), contacted Samsung tech support both online and via telephone. Everyone just says they have no idea.
So, if I have rooted my phone and unlocked the bootloader, is there a way to turn on global capabilities? Or even easier, can I just buy a SIM card from a European provider and insert and it will work?
I appreciate any input on this. I am new to using a smartphone in Europe but I can't give it up now for even two weeks.

Just wait for the ota. Im due for a dominican republuc trip in 50 days. If i dont get the unlocking OTA before my trip im raising hell.

I want to know what people who live on/near a border do? If you live in US very near the Canada border, how do you stop your phone from roaming back & forth and bending you over on "international" charges, even though you technically are in the US.

Here is the thread you were looking for..

Thanks for responding. I did find this thread a bit after I posted. Working through the steps.

Just a quick question on this topic. I've received the 4.1 OTA update from Verizon for the Galaxy S3. This update was supposed to bring global roaming capabilities. My question is, what does this mean? I know the thread linked above allows a Galaxy S3 to use other 3G networks but that involves rooting and complicated setups with APN (which, while I can certainly do, I'd rather not).
So, what does the default 4.1 configuration on Verizon get me? Can I go to, say, Japan and pop in a 3G SIM? Or is "roaming" simply roaming on any CDMA network? Is Verizon going to charge roaming fees?

I had a similar question and called Verizon. They confirmed that the 4.1 update unlocks the sim so that you can use any carrier overseas. However, if you need to modify APN's, good luck. There is no easy way to do that I've found without rooting. I'd rather not root my phone. I'm going to PAris and Rome in April and was hoping to use a sim card from iphonetrips. They have the best deals for unlimited data depending...

Questions about this phone unlocked.

Is it true I can simply put an at&t sim card in the phone and use a dumb phone plan if I buy an unlocked ones? Also does it get at&t 3g?

Besides SIM unlocking you need to perform the US band unlock as described both here, on Rootzwiki, and who knows where else, to use the DROID2 GLOBAL on AT&T or T-Mobile.
As AT&T uses standard WCDMA bands, yes, it will work with their 3G voice/data network as long as the band unlock hack is in place.

I doubt there are a lot of band unlocked D2Gs on sale as reflashing the SBF image breaks the hack.
You can perform the hack yourself provided you buy a SIM unlocked device.
Refer to http://forum.xda-developers.com/showthread.php?p=22769743 for instructions. Do note that whenever you soft-brick your device you will need to SBF back to 2.4.x and apply this hack.
Remember to never ever update the device to 4.5.629.

Dumb phone plan from who? If you get everything done (band unlock as described in the other posts) you can use your phone with an AT&T SIM and don't need any plan at all from Verizon. Is the theory that AT&T won't recognize it as a smart phone because it is not one that they ever sold?

Any non-carrier-locked GSM phone that has compatible bands can work on AT&T's network. You don't even need a list, just check which bands AT&T uses and check the phone's tech specs.

I think the problem is that people don't want AT&T to recognize the phone as a smartphone and helpfully add on a data package on postpaid plans, (presumably these people are intending to use Wifi for data). The claim was made that some people had moved a SIM from dumb phone to a smartphone purchased elsewhere, and suddenly they got billed for a data package. See, for example, http://www.zdnet.com/blog/bott/can-at-t-really-add-a-pricey-data-plan-onto-your-wireless-bill/2667
In the past, there were posts saying that you were "safe" if you used a model that AT&T had never sold, as their system would not be able to recognize it as a smartphone. Not sure how true this really is!
They probably detect it based on IMEIs. But yeah, it's just a speculation without clear facts.

Does the new JB update bring unlocked 3G GSM?

I've read that the update will bring new global roaming capability, so has anyone tried to stick a GSM SIM into the phone yet? Does the new JB update bring unlocked 3G GSM?
No, it does not. I updated to 4.1.1 bone stock and got it to register on T-Mobile's network, but there is no way to change APN's, so data and text/mm do not work.
Now, before the update you could root and get a program to add in the APN of whichever network you wanted... folks (including myself) have had it on AT&T and T-Mobile's GSM networks, albeit without WCDMA ("3g"). Check out http://forum.xda-developers.com/showthread.php?t=1895684 for progress on getting WCDMA working on the 1900 band. The phone works on the 2100 band out of the box, but no US carrier uses that for WCDMA.
Okay, that said, post-update, I am sure the same APN tricks that worked pre-update, will work now, but sadly one has to be rooted to do that. Attached are two screenshots from while I was farking about with it.
Why not root, then? No disadvantages that I can see

To be honest, I'm amazed that VZW is allowing you to use another carrier's GSM SIM at all without some sort of unlock code (since this is the case with most phones sold in this country).
I assumed that their "Global Roaming" capability meant that you can take your SGS3 with the VZW SIM to countries (e.g. everywhere other than the USA) that only have GSM (WCDMA/HSDPA) and pay Verizon's extortion (roaming) fees. Maybe the lack of unlock is due to the fact that the phone's primary radios are LTE and CDMA?
If someone can confirm that rooting the phone will allow you to change the APNs it would be greatly appreciated. My family is vacationing in Costa Rica this winter. I've already acquired a couple of unlocked AT&T phones that we plan to use with local prepaid SIM cards, but it'd be nice to be able to have the option of using my I535 there as well.
Thanks!

Its not as cut and dry as that. If you have to root the phone to move carriers technically you are in the wrong. If that is what you mean by unlocked.

Actually you are wrong. He is referring to the FCC ruling. And we should not need to root to be unlocked. I think that is the point he was trying to make.
Does the inability to change APN affect only the domestic US carriers or is it true for any country's Sim card you put in for gsm use. (Verizon global phones have in the past operated where domestic sims don't work but international ones do)

I recently updated to the leaked K3 while traveling on business in the Philippines. While voice and text work, there is no way to add any new APN settings in both GSM/UMTS and Global modes. When clicking on Menu in the APN settings, the only option is to restore to default.
Note that while voice and text do work, there is a notification i the notification menu stating "Non-Verizon SIM: Sorry, this SIM card is not supported. Please..."
I believe that the frequency the carrier runs on is GSM900. Hope that helps clarify things. I spent way too much time trying to get 3G to work over here to no success.
Has anyone just tried using Verizon's Global Data Plan ($25 for 100 MB)? Is the S3 somehow not compatible with that plan?
I'm looking at getting the VZW S3 but I've heard all kinds of things about getting the Verizon S3 to work globally pre/post JB update. I know the local sim rates are much cheaper, but for an occasional traveler this is supposed to be the easy solution.

[Q] How do I add APNs on Verizon Galaxy S3 running 4.1.1?

I have a Verizon Galaxy S3 (SCH-I535) running Android 4.1.1. I was told by Verizon prior to moving to England that, with this version of Android which unlocked the "world phone" capabilities (GSM), that I would be able to use my phone abroad with a new sim on a local network.
Fast forward a few weeks, and I am in England with an Orange sim in my phone. I have no problems with voice, but I cannot access any data services (I have no trouble receiving texts, but cannot send them - I think this is a problem with the sim though). After searching around the internet for a while, it seems that the solution to my problem would be to add the Orange APN settings to my phone.
HOWEVER, Verizon's version of 4.1.1 does not allow you to edit APN settings! When you go to the APN menu, there is nothing displayed and the only settings option is to Reset to Default.
The closest thing I've found to a solution is here, but it's a bit out of date as the method isn't for 4.1.1. I'm a bit wary of rooting my phone and installing a rom, as I've never done anything like that before.
Does anyone have any experience with this sort of thing that might be able to offer a solution? I would be willing to root my phone if necessary, but I'd need to be directed to a pretty explicit noob guide for doing that :silly:
Thanks!
Getting root is easy with the toolkit linked. Should you have any questions you can read the thread or search galaxy s3 toolkit on YouTube. Just keep in mind some videos are outdated and that you have a Verizon cdma galaxy S3 running 4.1.1.

What ended up being your solution?
I'm going to Italy tomorrow with a Verizon S3 and APN settings are locked. The phone is rooted and I would love to be able to use a local SIM on data!

No solution yet. I'm going to look at the link above when I can get some time to sit down and focus on it. Hopefully it fixes it.
BTW, although it's billed as a CDMA phone, it is able to operate on GSM as well. That's the whole "world phone" thing that Verizon has been talking about.

I understand it's a world phone, but I wanted to drop that in because I wasn't sure if the Toolkit states "CDMA" under the device selection screen. I know the Galaxy Nexus or Razr Toolkit specifically stated CDMA. I just didn't want you to accidentally pick the wrong one. After looking at screen shots of the Toolkit you shouldn't have a problem it doesn't mention CDMA only Verizon is stated.
Unable to add APN.

Hey there,
Sorry for going there, but I have not been able to find a fix for adding in the APN on a Verizon Samsung Galaxy S III. I have it on Cincinnati Bell at the moment, and have it rooted. I have voice and text, but not data. I have used the APN Manager Pro to see the APN that I need to use, but for some reason it will not use it or be able to edit it? Any thoughts?

Spiting Verizon is my new favorite hobby.
I have a very similar problem. I have a Samsung S3, not rooted, but unlocked from Verizon. I have been in Kandahar for a month or so. My SGS3 with a local provider will make and receive calls great when coverage is there. My problem is, I can only seem to text local here not back to the US, or get email and no Google Talk. I went to the shop where I got my card here, they told me that Verizon needed to unlock my phone. I know it is unlocked but I made the call home, Verizon told me what I already knew. I went back into the store, once again, next they said Verizon needed to unlock my APN? I called again, finally I got a response from Verizon saying that Samsung needs to release the patch so Verizon can unlock it. If anyone knows of such a APN patch I would greatly appreciate it. My lap top screen got cracked during a patrol so doing all of this and email is quite the B!tch! I have always had success with this forum and hope it will continue. Once I send my lap top back home to be warrantied, I will not have any way of getting the usual business done for at least a month. I'm trying to hold off on the lap top until I can get my phone fully functional. I do not have internet connection on my phone, just my computer, I guess that is the APN, that is still locked. I could do all of this if I had WiFi, but it is not allowed here by the company that provides internet. They do have WiFi in some areas, but it is always bogged down with everyone else trying to use it. Also, I am not too sure if I want to attempt to do a root, the internet service here is very slow. Thanks for your help. Please remember, I am atleast 8 1/2 hours ahead of you, so response time will be delayed.

SCH-R530 from US Cellular - why no worky?

Hey ladies and gets,
I am new here and I do not have much experience. I have been on an android binge for a week now and I have read a lot of threads, and flashed my phone so many times already.
Here is the info:
Samsung Galaxy SIII (LTE I guess)
SCH-R530, and in some places it shows SCH-R530U
Currently running on the latest nightly cyo..10.2
IMEI starts with 99000... and I have checked its not stolen or anything - there is also a sticker behind the bat that confirms it.
Originally a US Cellular Phone, I want to get it working with T-Mobile.
Things I have tried:
-I got the Samsung Tool Kit (donated), received all the updates - and the phone still does not unlock the network operators.
-Used a method from youtube - CDMA Workshop - connect to the serial port - security - samsung defaults - screen on pc says unlocked but phone is not although it is answering to the program.
- No option for the network lock as known in the 530
-Used three different online services - but they said no can do.
- Called tmobile - and placed a request and they said - that IME does not correspond to the model of the phone(???)
I am a student, I can't afford to get anything else - so please help or point me in the right direction. Thank you
I don't think you can do it.
I don't believe it will work because Us cellular is cdma and T-Mobile is gsm.

There seem to be different opinions on the net. Phone like mine have the added abillity to receive CDMA radios i guess, but they do not lack any of the hardware for gsm.

Just a little update:
I have not been able to make any progress at all.
I have updated my 4.3 on the regular basis - however when I did the nightly 6, and 7 both locked up on the boot menu.
Anyways, today i reinserted my tmobile sim card and when I try to make a call - I get Verizon Wireless automated services that say that i can be transferred to complete the call with a credit card and stuff.
Why verizon? this is a us cellular phone?
Also when i switch to gsm mode - it still does not locate any tmobile operators?
US Cell phone is a dead end. This thread might as well be deleted.

Vzw bought out USC... in some areas I believe? Any how now no the USC will not work on T-Mobile. At least not stock....yet. It may be possible to get voice working but that would be about it. If you could vet data the most it would possibly be is edge as far as I know.... If you want to try something I would try flashing a sch-i535 ROM of 4.0.x-4.1.1 Odin would be best but do not flash the radio/modem. I am not Of 100% on this but Odin might skip over the modem if flashing i535 ROM to the r530. If not mobile Odin is able to only flash selected partitions of choice. Make sure you use a pre rooted ROM. After that and it is successful you may be able to follow the guide posted some where in here on how to use the i535 globally. It will require APN pro I believe. And another app to be able to select gsm global (don't recall for sure) if you find the guide it will tell you. . good luck and let me know if that helps.

[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.

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
