Hi all,

With Verizon releasing officially, the update making its SGS3 Global ready atleast for voice as of now, a lot of discussion is happening right now about the Global capabilities.

FYI. I'm a good reader and explorer on hofo,androidforums and xda. So any guidance is highly appreciated
So here is my question.

I have a Verizon S GS3. It is brand new.

1. Can I use it with Straight Talk T-Mobile SIM ( T-Mobile has good coverage near my house ) after doing the rooting, unlocking, etc. etc all the technical stuff

2. If I unlock the phone, will it be truly global capable, I mean, can I use my S GS3 on any GSM Network in the World, even in the USA, with 3G Speeds? Did anyone use it in any Country with 4G LTE Speeds?

3. I know this is really a very very strange question. But after unlocking the S GS3, will it be working on the AT&T LTE Netowrk in the USA? My thinking is, if it working in the LTE Network in the USA, then it will work in other countries as well, where LTE Network is going to be available in the future. Sorry, I know this is a bit weird.

If You can please refer and threads or links, it is fine with me. I'm also looking and not depending only on the answers that I get from this thread. But looking for replies/guidance/links though.


Thank You.

Thank You.

for Q1:yes you well be able to use any network... install any mod now most of them are already rooted and unlocked
for Q2:yes you can... all you need to ddo is to download a program called hiapn.. wipe the existing apn settings.. then auto detect and you are good to go 3g and hspa
Q3: yes it works thanks to the magic of hiapn software... but not many countrys use LTE .. usa canada japan and maybe few others

Smile Verizon SGS3 on any GSM Carrier
Hi experts,

I have a small doubt here.
If the Verizon SGS3 can be used with any GSM Carrier around the world, then that means, the Verizon SGS3 can be used with AT&T or T-Mobile as well along with Verizon Network.
But the T-Mobile or AT&T Versions cannot be used on the Verizon's Network. Is that true?

I'm have got a traveling assignment coming up to Europe this Summer and I need to know what is the best possible solution out there before I leave.


Thank You.

Verizon's GS3 uses CDMA technology for the phone calling and data, as far as I know the SIM in the verizon version is only used for LTE.
From what I have read in forum posts, (this one in particular http://forum.xda-developers.com/show....php?t=2013647) if you pop in a SIM card, calling and texting should work. If you want data to work then you need to change some APNs around. Stock touchwiz does not allow this so you would need an app to do that. AOSP ROMs should have a way for you to edit APNs.

On the topic of getting 4G on any other network besides Verizon, that is fairly unlikely as they all use different technologies/ bands. Verizon has LTE, T-Mobile has HSPA+, not entirely sure what AT&T has but I think its also LTE.

This phone will take any SIM card cut to micro-size.
3G+ speeds depends on the frequency the carrier uses. The VZW GS3 uses the following radio frequencies after the JB update: GPRS/EDGE/GSM (850/900/1800/1900); HSPA/UMTS (2100) [I had to search high and low to find this for my trip to China]
Each LTE carrier uses different radio frequencies, and global countries also use LTE frequencies different than the US ones. 4G is a very varied standard at the moment.
If you want fast internet on a non VZW carrier, it better have HSPA+, otherwise you are on 3G at best.

Right now, the only truely global phone is the iPhone5 on VZW, which supports 5 different LTE frequencies. Sad but true.

The US based SG3's dont even have the FM radio that the international versions have

Yeah, my girlfriend has a verizon s3 and with straight talk she is only on edge it never changes. It makes the phone nearly useless. Ive tried to talk her into letting me flash and unlock it but she isnt real interested in it. I dont even know forsure if unlocking the bootloader downgrading to 4.1.1 and using the att sim unlock method would work but I would assume that flashing it would allow you to at least get 3-4g. not?
