Using 3G data in Europe - Verizon Samsung Galaxy S III

So I'm looking into traveling to Portugal this summer and I'm wondering if I can grab a 3G data only card from Vodofone and pop it into my S3. I know the phone needs to be unlocked for this to work and I have seen a long involved tutorial on here on how to unlock the phone, but I've also heard Verizon will unlock a phone for you if you are a customer in good standing. Is this true? If I can get Verizon to unlock my phone should I theoretically be able to use this data sim card in Portugal?
Also, I know Vodafone lets you make calls to other Vodafone users for free, will I be able to do this if a get a sim card with some prepaid data on it only? Am I still considered to be on Vodafone's cellular network?
Thanks so much!
As a side: If anyone has an experience with Vodafone's 3G in and around the Lisbon area let me know how it is!! I'm mainly looks to tether my phone to a laptop and do some development work while I'm over there.

Would you happen to have that link yo the process of where you can unlock the phone? Or you just mean the process for changing the apn

I'm pretty sure the thread they're referring to is the GSM travel thread. If using a JB TW rom, one just needs to edit the apn's like you mentioned.

Got it, thanks!
I've also heard that the Verizon GSIII does not have the radio's for internation GSM 3G, is this correct?

I would say that's incorrect given the thread I posted which contains plenty of user experiences contradicting that statement. I'm eager to do this myself if I travel again this year.
The primary thing you just need to do is have an international sim and also use one of the mentioned apps that adjusts your APNs.

Thank you! When you say 'international sim' do you mean just a sim from another country or do I have to ask for some specific type of sim card? Meaning, if I got to a Vodafone kiosk and get a prepaid sim card would it work?

Yes, I mean a sim from another country.
From what I've read, that's pretty much what you do. You just pay for whichever plan you want then follow those steps in the link. I can't speak from experience so I'm useless there. Depending on the carrier and country, some folks seem to have gotten HSPA others have gotten 2G. I'd love to know what you're results were after your trip either here or in that thread.

Will a Nexus S 4G get data in my country?

I bought a Nexus S 4G off ebay, and i would like to know if its going to be able to use data on my country. Someone told me that its not possible because its CDMA, but im not sure if this is true, and would like to hear second opinions.

Yeah, i should have gotten the GSM version..but this one was cheaper.
I live in Dominican Republic, and im currently using VIVA as my phone carrier, but i can change to Claro RD if they offer data plan for CDMA phones.
if its a CDMA carrier u can try giving them ur esn number..but u will have to flash the phone to work on there network.. u may b able to take it to a carrier store and they can take care of it..

I know they can take care of it here, i know it can be activated here, but my doubt is with the data, if im going to be able to use data here.
The odds are against a carrier store being able to enable data on a flashed phone but if you can follow directions and are slightly technology literate you can track down directions to enable data yourself once it's flashed.

I think i can do it. I set up my apn everytime i flash a new rom on my Vibrant...which is like at least 2 times a day, or more.
Im getting the phone in my hands in one or two days at most.

Looking for new carrier..

Hey guys, I am using Simple Mobile because they have a decent unlimited everything plan but i cannot get 3g. It is odd because my phone is an unlocked T mobile version of the galaxy s1 plus. Simple Mobile uses Mobile.
At any rate, is there a comparable carrier that would give me 3g with unlimited everything?
I am in the USA btw.
Is there any chance i am doing something wrong with set up? Why would a TMobile version not get 3g with Tmobile?
One more question. My phone says TMobile but it is unlocked. I can use it with any sim card? right?
So sorry for all the questions.
Thanks for the help,
Richie

You should be getting 3G with your T-Mobile branded phone, maybe you didn't set up the proper APN's. Follow the link below and find your phone, enter the correct APN's if you havent already. Your T-Mobile phone shouldn't need to be unlocked in order to use it under Simple Mobile, but since it is unlocked, you can use it on any GSM carrier around the world. Speeds might vary depending on the frequency.
http://www.mysimplemobile.com/Support-Center-Phone-Programming.aspx
Yeah, i did that when i first got the sim. My phone doesnt have the frequency for 3g but it just seems odd because it is a t-mobile phone. I am not sure if it is a problem with simple or t-mobile.
Thanks for you reply,
Richie

Can I simunlock i9020A for international use?

I'm about to buy a Nexus S i9020A (AT&T) on eBay, but I need to know if there's an application here to simunlock it or a good site to buy a code (if you have a website, please tell me price). I've been reading and in one thread someone replied saying It's already unlocked and that Nexus device sold has always been sim unlocked (even those sold subsidized by the carriers)... so I don't know what to think about it. In another thread the user said he bought on in Craigslist and he said it was unlocked and rooted... which got my attention the "unlocked" part... so, there's a way to simunlocked or not?
Please help me.
I'm waiting for your response to buy it.
Best regards.
It will probably be unlocked but if it isn't, the Nexus is is one of the easiest phones to unlock. Look up a tutorial somewhere here on xda, or wait for a more senior member to give you his advice here.
Good luck

"Unlocked" wrt/Nexus S refers to bootloader unlocking. IIRC the Nexus S cannot be SIM-locked at all - the baseband doesn't support it.
It doesn't need to be Sim unlocked. They are all unlocked by default.

It's obvious it doesn't work with a T-Mobile SIM card.
The Nexus S GSM has 2 versions:
i9020A, working on HSDPA 850/1900/2100
i9020T, working on HSDPA 900/1700/2100
Both are GSM, but different bands. They're not "software locked" but simply unable to connect because it's a modem issue.
So if you have a T-Mobile SIM, you need a Nexus S whose model number is I9020T

Exact.
Not exact. T mobile will work just fine. T mobile 3g data service will not
All gsm networks will work on any 9020/9023. 3g not so much

Wrong again, in parts. Since we're not talking about the US only.
Not all operators around the world actually serve their users with 2G. Just up north, in the beautiful country called Canada, many operators only offer 3G, including mine. Thus, in the end, you end up with no service if 3G isn't supported.

I see we have the same location Is Bell 3G only? I'm on Rogers and I use 2G unless im out of my wifi range.
*To be safe* if you have a T-Mobile SIM, you need a Nexus S whose model number is I9020T, and it will work without a doubt

Hey, I have a similar problem, I bought a nexus S i9020a second-hand and flashed it to JB using Nexus Root Toolkit...I am getting no service. Something must have gone wrong, the sim works in my other phone and I have tried calling my wireless provider rogers to repush the sim card anyways. Any help would be appreciated, thanks!

You need a i9020a for Rogers, so that's good. Check for broken pins in the SIM slot. Happens too often with the Nexus S.

Used SIM & Pageplus

I bought a used TB and the guy did not take out his SIM card.
I am going to flash this phone to Pageplus.
Does anyone know if having his SIM card in there might mess things up? Pageplus does not give you 4G and I'm ok with that.

I'm pretty sure you may want to keep it.
From my understanding, in order to flash it to Page Plus, you need a dummy SIM anyways.

FYI....I did it without a SIM card. It doesn't seem to care. No 3g yet with or without the card.

Did you use your normal Verizon SIM? I'm trying to find a way to flash mine to Page Plus as well but I don't have a SIM to fit it, other than my old one.

I don't have a Verizon SIM of my own. I bought the TB used and it had one in it. I'm afraid to stick his in there and screw everything up. Leave it out, you don't need it to get voice, txt and 1x data. I can't help you get 3g.
I used an old cingular SIM card as my dummy SIM, and it's working, just no 3G yet. Followed this guide:

Once I hear back from the author to clarify one of his steps, I believe I will have 3G working. It seems to be the only guide that doesn't require paid software, AND gets you 3G

The short answer is no it can not be done Verizon is a cdma phone the other is a GSM phone.

Post #48. If you do not have data, you need to root and edit your APNs using the steps on the first page. Highest speeds you'll get for T-Mobile/AT&T are Edge (2G).

Actually, there is a GSM setting on the phone, and from my understanding, the GS3 is a world phone, and I think the I535 has the proper antennas to work on AT&T's 4G network, but I may have to look into that. It was something me and one of my coworkers were gonna try, but never got around to and he is now in the military, he had a AT&T GS3, me a Verizon, and we were gonna SIM swap and see if it worked. Hardware seems to support it would, but the big question is why?

Unless there's a breakthrough in this bounty thread, highest speeds you'll see on AT&T or T-Mobile are Edge. Hardware supports "up to" HSPA in other countries given differences in frequencies. Not sure I get your question of "why?" though. Samsung made this phone to support virtually every carrier in the US and it makes more sense to hardware lock (or carrier lock or whatever the technical term is) phones to only have access to most common frequencies in that region.
My question as to why is to the whole carrier swap. When you sign a new contract, you get a new phone, adding a customer owned device doesn't change plan price, but does maintain the upgrade eligibility. As far as I know, the major players haven't started releasing specs on next years devices. So, why the want to take a Verizon GS3 to AT&T is what i'm wondering.
Agreed, although I could understand if he said T-Mobile it makes good sense on their new plans. This just isn't a good idea trying to bring it to AT&T

Yea, I always thought AT&T had similar pricing as Verizon (expensive) but I'm not one to inquire into folks personal decisions on switching carriers with this phone. I'm only interested in doing so when I travel overseas. Everyone has different needs, you know?

Yup, same process for AT&T and T-Mobile so long as you have the respective sim. I'm unsure if you can edit and save APNs on stock which is why I say if you have no data then you need to root for the method I linked to. You can get calls easily on stock, just have to adjust Network Mode accordingly.
