so there is no way to use an AOSP rom with this? I really like 4.2 but not being able to use global is a deal breaker.

When I pop in a foreign gsm sim, it requires me to put an unlock code directly after I boot. I'm on beans 10 rom. Anyone experience this or knows what to do?
[Verizon Samsung Galaxy S III] kl323:
This is a pretty long thread.. my question is... Can I call Verizon to have them give me an unlock code? I previously did this w/ my BB Storm (world phone). Does it still work like that with these 4G phones?

Thanks!
[Verizon Samsung Galaxy S III] wethead4:
Turns out there is no unlock code. It was an unlock code for the foreign sim (some providers put a code on there sim i guess). anyways, i followed the directions in this thread, - installed APN app made it a system app with titanium backup. Edited the APN using info from the mobile provider (one from those websites in the post was wrong for Globe in the Philippines) and i'm up and running with HSPA+. Took 5 min tops.

Working in Australia with Considerable Pain....

Hey All,

Firstly thanks to all that paved the path forward for all of this!!!!

I am running beans106 stock build 15 ICS on VZW SGS3 and am in Australia right now with a H+ data connection on AMAYSIM who are an NVMO on the optus network.

Before I left the US, I tried out the page 11 with an H20 prepay on ATT and managed to get voice, sms and data so I thought I would have no problems overseas. Got to Australia and popped in the sim, got voice and sms no issues but could not for the life of me get data.......

After much pain, installing jelly bean, changing modems from VRLHE to VRBLK3 etc etc, I finally removed APN manager PRO and installed HiAPN and then got data on jelly beans build 12 from beans106. I then did a nandroid restore back to my ICS and got data using HiAPN with it but only after changing to "gsm only" for just a g connection and then to "gsm with auto prl" for an H+......

Conclusions

1) APN Manager Pro would not work properly for the Australian networks. HiAPN with auto detect worked perfectly!!!!! and its free

2) With Jelly Bean I did not need to change away from Global but with ICS the optimum setting was gsm with auto PRL

3) I left the modem at VRBLK3 but am pretty sure it was APN Manager PRO giving me the head ache.....

I hope this helps someone else out in the future....

Cheers

I followed the steps on the shortened version but I ended up with only edge. Is there anyway to get H+ on rogers?
[Verizon Samsung Galaxy S III] macman159:
Are the steps the same for the JB OTA update? I ask this because verizon allows foreign sims (other than domestic sims) to be inserted for voice and text. However, no data is allowed. Do I just do the APN thing and I will be good or no?
[Verizon Samsung Galaxy S III] SlimSnoopOS:
All you need to do are the APN steps. Just change your network mode to global or GSM first.
[Verizon Samsung Galaxy S III] odoyle81:
I'm in the Philippines now and I can confirm the instructions from post 106 was super easy and works great. Just buy a sim card, add the APN and you are good to go.

btw, you don't need titanium backup or - just move the APN manager to /system/app and change the file permissions:

http://xdaforums.com/showpost.php?p=37453657&postcount=420

Also remember you need to change to global mode with phone info app, and allow mobile data and allow global data and "use packet data".

So you don't waste prepaid minutes, turn the mobile data off when you aren't using it.

For reference, I'm on ICS with verizon, and in the Philippines I got a "smart bro" SIM.
[Verizon Samsung Galaxy S III] macman159:
do i change the APN before I pop the sim in? or do i do that after? thanks
[Verizon Samsung Galaxy S III] DataGov:
Back in USA after trip to Africa

I used the steps in this guide with APN Manager Pro to setup my i535 Verizon SG3 to work with the MTC Network in Namibia. I had great data and voice for three weeks. When I returned I pulled out the MTC sim card and popped in my verizon sim card. Now I get 4G data, can receive SMS, but get no dial tone, can't call out or receive calls, and can't send SMS. I've tried several ROM's (clearrom, synergy, liquid, and stock rooted) and nothing works. Stock rooted JB gave me the error message "Mobile Network not Available."

I'm back on Clearrom now and still no voice or sms. I called Verizon and they are clueless. Got a new sim card and that did nothing.

Anyone else have this problem upon returning to the USA after using the phone abroad with GSM?

Followed all instructions got everything to work besides out going phone calls, how can I get out going call to work? (T-Mobile)
[Verizon Samsung Galaxy S III] lair@nc.rr.com:
It will definitely work in India, as I was there in January and used a Vodaphone card with few problems. You may need to try either the GSM ONLY or the GLOBAL setting using Phone Info app. Follow the instructions exactly and make sure you have the right apn information. One thing wrong will cause it to not work.

What do you guys recommend I do for a trip to Canada? Any specific SIM you'd recommend? I'm on CM10.1 right now, and apn manager pro crashes btw
[Verizon Samsung Galaxy S III] dieselboyx:
Speakout is cheap and has unlimited but proxied data.
[Verizon Samsung Galaxy S III] Wrngway:
I just got back from Thailand and was able to use voice and data on the DTAC network over there. $2 for the sim and $3 credit got me an hour and a half hours of data or voice. I also used Google voice to call the U. S. when on wifi. It's too bad GV doesn't allow international texts.

I was on Beans13 ROM and used APN Manager Pro (sets a system app) to swap the apn. The whole process was easier than I thought it would be.

I curious if any one has tried this on an aosp ROM. I should be tried it out while I was there.
[Verizon Samsung Galaxy S III] lair@nc.rr.com:
I'm the original OP, and can confirm that I have had great success with my SGS3 using the info in this post with my latest trip to Morocco. I'm using Maroc Telecom, as I tend to use the largest provider in the country I am visiting.

My continued success with this setup has been so consistently good, I've actually done no updates for 6 months as I don't want to jinx the system. Anyone know if Verizon has actually unlocked the stock ROM yet (as promised over a year ago).
[Verizon Samsung Galaxy S III] _sadpanda:
Short answer, NO.

I got all excited about the preliminary rumors of JB being unlocked so I used the no wipe JB upgrade method then allowed OTA to 4.1.2.. kind of a mistake. The stock verizon JB unlocks the band selection (so phone info app not needed necessarily) but adding APNs is locked out. APN manger pro is a dead app and should not be purchased by anyone anymore but either way, it does not work with JB. Offline APN list also seems dead (opening warning message said 'this app not compatible with ICS' or something to that effect)

I still have my two Sims from my last trip (T-Mobile klax Austria and Blau.de) and the only thing that seems to work is HiAPN.

I was able to successfully backup my existing APN, swap Sims and automatically load apn info AND reverse it all with this ugly app. I won't be able to confirm dull functionality until my wife tries it out next week on her solo trip back to the region. Fingers crossed.

I still recommend backing up your iemi number and your dialer and using talkatone/google voice. If you have ICS rooted still and it's working, stick with the old method as described by the OP and myself/et.al. If you are on JB stock you are going to have to root and use HiAPN or apparently flash a non stock ROM. In reality, HiAPN is easier then the old way but it's translation or lack there of makes me actually appreciate the eng-rish in Harbor Freight manuals. Sad. I hope someone comes out with a better translation or app soon because I seriously doubt verizon will pull their heads out of their rears any time soon. Speaking of...

F verizon for screwing up this awesome device.
[Verizon Samsung Galaxy S III] Mix3d:
Agreed on the Verizon bit. My experience with stock JB while in China was that as long as you have root, you can make it work.

the above mentioned programs need root access but were not built well to ask for it. Putting them in the system/app folder and changing the settings in these apps to ignore the ics/jb issue has had them all work for me, but the infamous hiAPN does the best job in terms of ease of use, even if its Chinese origins make it sketchy.

My 2 cents.
[Verizon Samsung Galaxy S III] Gatanater:
Do alternate steps need to be taken if I'm running CM10.1?
[Verizon Samsung Galaxy S III] Mix3d:
Depends on if you can enable global mode with CM10, and if you are able to manually change APN settings. Stock Rom users are unable to change the apn settings, which is why we need the work arounds.

Success with Airtel India

Just came back from a trip to India. Used my VZW White S3 with Airtel. Signed up for a 10GB 3G package for ~$30, and used it to tether my laptop/tablet for work.

Used a Samsung based ROM initially. had a tough time getting it to work. Used Phoneinfo and APNMgr to set the radio mode, and Airtel APN, but it was hit and miss. Finally switched to AOSP ROM, and it worked perfectly.

Thanks to op, and other contributors.
[Verizon Samsung Galaxy S III] djteotancolis:
I am going to India soon too, and plan to use Vodafone or Airtel. Which AOSP rom did you use? and could you edit the APN's without the need of APNMgr?
[Verizon Samsung Galaxy S III] gtab55:
I will be travelling to Germany soon and need the S3 to work. IS this method still operable?

Hey guys, I will be going to India in a few months, and I wanted to know how do I make my phone work in India? I wanted to know because I still can't put my finger on how to change my apn's. Do I just change APN's using HiAPN? Can someone please tell me how to do it step my step, or show me a video? Some people said that the steps for Jellybean are different. Also, is AOSP easier to work with when changing APN's? If so, can someone give me steps for AOSP ROMs?
[Verizon Samsung Galaxy S III] hkk:
Steps I followed for Airtel India

Just follow the steps in post# 106 below.

http://xdaforums.com/showthread.php?t=1809314&page=11

Certain things I did different, and worked for me are.

1. Use AOSP based ROM. I tried 'Jelly Beans', a Samsung based ROM, and had tons of problems. The ROM I used is this.

http://xdaforums.com/showthread.php?t=2148261

2. In step B, do sub-steps b1 & b2. I had to set the network type to 'GSM Auto (prl)'.

Reboot (Not always required, I think)

That's it. Good luck.
[Verizon Samsung Galaxy S III] claribanter:
So, I've been using the d2vzw as a gsm phone in Europe since February. I was using Beans stock rom for a while and have tried CM10.1 a few times. CM10.1 finally supports GSM. Basically, any ROM as long as you can use phoneinfo to switch to gsm and use one of the methods to add the correct APN settings things go pretty smoothly. I've used HiAPN to set up the APNs automatically on 'Beans' Rom without a hitch. On CM10.1 you can just add them manually in the settings.

The only issue I've been having is with the signal strength. The phone frequently switches to 2g even though there is a solid 3g connection. If i switch it to WCDMA only it will connect to 3g. If i leave it on Global or WCDMA preferred, or GSM auto PRL it will eventually do this. It seems that I have much worse battery life because the phone starts to get hot from searching for a signal. Has anyone else experienced this? Anyone know a possible fix. I just flashed the latest CM10.1 nightly and using the VRBMB1 modem and RPM. If you haven't had this issue, could you tell me which modem you are using?
[Verizon Samsung Galaxy S III] speedybishi:
Thank you to everyone that has made this possible. It will be a life saver when traveling abroad. However I am having a bit of trouble... maybe someone can help me out?

I have followed this procedure and am confirmed working on T-Mobile's network in the states, so I purchased this - - http://www.telestial.com/view_product.php?ID=MSIM-PPL2 -

When I try to connect with this SIM, there seems to be something wrong. If working properly, it should automatically prompt for a PIN # to unlock the SIM. Generally speaking it does NOT do that. With no rhyme or reason, once every 40-50 reboots, it seems to prompt for the unlock PIN. When it has asked for the PIN unlock, everything works great. Upon the next reboot, it does not work again.

At first I thought maybe it was horrible cut to make the SIM a micro (telestial cut it, no me). So I asked them for a replacement, but am getting the same problem.

To add to the confusion, I put the telestial SIM in my ipad (I know, Apple... BOOOO), but it works.

Any thoughts?
[Verizon Samsung Galaxy S III] ragrave:
I need help. I follow every step but couldn't get 3g, only 2g. I have only gsm/utms not gsm/wcdma.

Carrier is DTAC in Thailand. It has 3g on 850/1800/2100.j
[Verizon Samsung Galaxy S III] lair12:
Re-do all your settings. Check APM... http://www.unlockit.co.nz/mobilesettings/settings.php?id=93. Ask DTAC if this is correct still.

Use PhoneInfo to change to GSM or Global mode (or try others if necessary). Use HiAPn to set proper APN (is your DTAC showing as the APN?). What is showing in Open Signal Map app widget?
[Verizon Samsung Galaxy S III] ragrave:
I think PhoneInfo can only view information. I don't know how to edit data by using it.

Most of the people get GSM/WCDMA. Why mine is GSM/UTMS?
[Verizon Samsung Galaxy S III] lair12:
You have NOT followed all the steps. See b3 on post 1, or b2 on post 106. I suggest you go to post 106 and start all over, step by step.
[Verizon Samsung Galaxy S III] ragrave:
Ok, I found the correct phone info app. I follow instruction on post 106 but still couldn't make it.

I tried Global but 3g still didn't show up.

So I tried other settings like LTE/GSM/WCDMA but it doesn't keep this setting.

For Example,

If the previous value is Global.

I change to LTE/GSM/WCDMA.

Press back.

Enter Device info again.

Value is still Global.

Any suggestion?

to unlock the phone, i must root it.

but for example the app "skygo" don't work with rooted device.

i've tryed to unroot, but with the unroot the phone comeback locked.

so the question is, it's possible to unlock, without root?

or maybe unroot but without deleting the apn info?
[Verizon Samsung Galaxy S III] brandonbarlow:
If you download the app called ota root keeper there is a button that you can temporarily unroot. So you would root your phone, but anytime you would want to use that app, you would go to ota root keeper first, temp unroot, use your app, than after go turn root back on.

i'm finally at the right place

First off many thanks for this post this was exactly what i was looking for!

I recently bought a used galaxy sch-i535 in el paso and i was hoping to be able to use it in mexico on the telcel network.

My question is: should the phone be able to register on the network without the apn configuration ?

My phone doesn't register to the network for some reason (no calls or texts) i've tried switching the settings from global to gsm/utms and network selection from auto to manual but when i try to force it to register it says "unable to connect, try later"

And then it keeps prompting me to switch it to global mode which when i do, doesn't change anything.

Ok so i tryed with HiApn and now i see the Telcel apn info in the phone settings, that's great!

But i still can't register onto the network :(

please help me, i bought this phone and i can't get it to work. I would really appreciate your input.

[Verizon Samsung Galaxy S III] ULEWZ:
I was just searching the Galaxy Note II forum, and found a post to enable adding APN info under Settings/More Settings/Mobile Networks/Access Point Names.

Try this at your own risk, but I will try it later this year if no one else does.

I am currently running Axis Ver 21 Rom.

Basically you get a Build Prop editor (I used the free one with the gear cog).

1. Open Build Prop Editor

2. Hit the menu button (bottom left of phone) and select Edit

3. Scroll all the way to the bottom of screen and add these lines of code:

ril.sales_code=LOL

ro.csc.sales_code=LOL

4. Save the edited file by hitting the icon that looks like a disk at the top right corner of the screen (It will say File Saved)

5. Restart the phone

6. Now go to Settings/More Settings/Mobile Networks/Access Point Names

7. Hit the menu button (bottom left of phone) and select New APN

8. Check this thread for the APN info of the Country/carrier you want to use, and fill in the data

This is all I have verified that works.

Someone try this after performing the above (apologies if this has already been posted).

1. Power down phone.

2. Remove cover

3. Add new SIM

4. Put cover back on, Dah!

5. Power phone on

6. Go back to Settings/More Settings/Mobile Networks/Access Point Names

7. Select your newly added APN and see how things work.

I don't know if you will have go to Network mode and select something else.

I hope this works as the wife and I want to go back to Europe this year and I feel naked without my phone with data.
[Verizon Samsung Galaxy S III] yichen382:
Good recommendation for that Offline Sim APN app. its the simplest way to add APN. Better than Hiapn. Now i can go anywhere in the world with this phone. Thanks!
[Verizon Samsung Galaxy S III] Bluetoth10:
You can use APN Global https://play.google.com/store/apps/details?id=osatek.apn.global instead of APN Manager Pro.

Also converted to system application using titanium backup. It's free and already contains a lot of predefined APNs for the whole planet.

My note is:

deleting language.xml in system\csc folder will unlock a lot of system languages (root required!)

My question is:

When using local GSM card in Europe I can not send SMS with + sign at the contact mobile number for example in Ukraine:

+38050.... - no go!

050.... - works ok!

===> using go sms pro with SMSC settings inside the program is working, but stock appliction still can not send SMS to +38050.... It must be some stupid hidden toggle somewhere in .xml files!

MMS messages works both ways:

+38050.... and 050.... numbers are ok

I installed CM10.1 rc5 from here http://get.cm/?device=d2vzw and SMS are working! But I'd like to keep Sammy firmware.

Please help fixing SMS!

===> took secmms.apk from international S3 I9300XXEMD3 deodexed firmware = ALL FINE!

Verizon markets it as a global phone, so the "LTE" sim almost certainly doubles as a GSM sim when travelling. Since Verizon hasn't sim locked the S3, iPhone 5, or any of their other "Global" phones to my knowledge I doubt that they did with the S4.

I've read through a bunch of posts here and still a little confused on whether this works on CM10.1. (I'm on CM10.1.0.3)

Some say things just work, some say that there is not "global" setting so it's a no go.

Can someone verify one way or another?

It would be greatly appreciated.

I'm looking for a SIM card to try it out myself, but curious if it'll work in Japan and Korea.

[Verizon Samsung Galaxy S III] ddrum2000:
I would like to know if cm10.1 supports gsm and apn selection on the VZW sgs3 as well. To question 2, in Korea you need someone with a Korean residency card (citizen, premenant resident, or resident visa) to get you prepaid sim. That was the case last summer at least.
