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.
hope this is the answers you are looking for

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
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/showthread.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?
Dear All,
I recently got this device in Hong Kong and is hapi with its performance!
But I am still wondering if this device could actually use the LTE available in HK?
I knw the msm8960 claimed to be capable of utilizing all frequency of radio,
so is it possible that there is some soft lock in the baseband?
Could i flash the baseband or replace the modem driver from other device to access other frequency?
any idea is appreciated!
Thanks!

I think it has to modifiy the ROm and the hardware
I tried to figure out, if our Photon Q is supporting more LTE bands than 1900 MHz (#2 or/and #25).
-> http://en.wikipedia.org/wiki/E-UTRA#Frequency_bands_and_channel_bandwidths
On some sites there are reports for having another band. (Have to search again, I think it was 850 MHz, #26 or 700 MHz, #12/#17/#29.)
I have also searched for supported frequencies for MSM8960.
I found some BlackBerry devices based on that SoC and 2 different versions of supported LTE bands.
One version (UK) supported 4 in europe used bands und the other version (US) supported 4 in US/Canada used bands.
I think that the Photon Q is like the BlackBerry US version and supports 4 LTE bands in US/Canada.
If you need a few sites, I will search again and show it to you.
The strange thing is, if I set to LTE only (via 4636) I can see all 4 carrier (germany).
We have 3 bands with LTE on it, but I can only get signal to max 2 of them.
Band 3, 7 and 20 (1800, 2600, 800 MHz).
The weird thing is, that on band #20 (800 MHz) only 3 carrier are active, so it has to be band #3 or #7.
Maybe I'm missinterpreting things and thats just a sideeffect of crossing bands of LTE US and UMTS Germany.
On stock ROM there was another "secret phone code" to see what the phone-part is doing. (From qualcomm I believe.)
I think I will test it some other day, to see which band is active.
At last, I was never been able to "login" or "register" into my carriers network within LTE.
Please discuss about that possibility, I really want to find out, which frequencies are supported by our phone on LTE.

Dear Loader009,
Thanks for your information! I'm really impressed that you could actually search the carrier in 'LTE only from Germany!
Could you please share the version of ROM you are using?
And if possible, any screenshot? I really want it can be used in HK with LTE(1800, 2100 & 2600Mhz)
Also do you have more information about the secret phone code? I think it would be interesting
Actually, I noted that xt925 and xt905 are using the same chip MSM8960 with LTE usable in HK.
Is there anyone can locate the radio/baseband of their rom and port it for XT897?
I am willing to try it with my machine.
If this work, I think we could use this photon q all over the world!
Any idea?
Regards,
Vasco

Of course, I was just blind guessing the hardware for xt926 and xt907 are using the same hardware.
If not, there should be one chip controlling the modem channel of the device to be replaced.
But WHICH ONE???
Any expert in this area can solve this question? I am a dummy for radio stuffs
This seems like it's getting pretty interesting.

Dear all,
I'm also very interested in this topic since I imported a Photon Q to Germany and was wondering if it's possible to use the local LTE 800/1800/2600 bands.
I think the first thing we have to find out is whether the hardware is capable of using other bands than the 1900 band listed on the Motorola website. As Loader009 states he could see LTE carriers which are known to use different bands I assume the hardware can do it. Otherwise the carriers wouldn't have been listed, right? Maybe someone from another country with different frequency bands can check and confirm that he can see those carriers as well?
Thus, the limitation to the 1900 band should be software-made and could be modified by a developer. I hope someone can participate at that point as I don't know much about coding...
I'm using CM10.1.
I can't remember the secret phone code, I have to do research again.
This secret phone code only works on Stock ROM. (I stupidly deleted it, when it wasn't working on CM10 anymore.)
The one secret phone code I used to force "LTE only" was *#*#4636#*#*.
Please DON'T change the baseband (don't even tap on it).
This can do problems to you. (I had to use QPST to recover the supported frequencies.)
Also, developers (afaik) can't modify the modem firmware.
We also don't even know, which LTE bands the Photon Q is capable of. (Except 1900 MHz)
I've got my 32GB SDCard back and will test it in the next few days out.
I hope I'll find that secret phone code, I'll also make a few screenshots.
Got the code!
##33284# <- ##DEBUG#
It only works on stock afair!
I'll test tomorrow, it's about 3am now >.<

I have read the "QU_SnapdragonS4_White_Paper_FNL_Rev6.pdf" and found there following entry:
-----------------------------------------------------------
• Industry’s first fully integrated 3G/4G world/multimode LTE Modem: <<<Supports all of the world’s leading 2G, 3G and 4G LTE standards>>>.
It also includes integrated support for multiple satellite position networks (GPS and GLONASS) as well as short range radios via Bluetooth,
WiFi, FM and NFC.
• Designed for speed, compatibility and power savings:
Snapdragon S4 Processor MSM8960 chipset includes the industry’s only complete platform that integrates all of the world’s leading 2G, 3G and 4G mobile broadband modem technologies on a single chip. This new integrated multimode modem is based on an advanced, programmable architecture that is performance, size and power optimized for the fastest combination of modems available for:
- LTE FDD/TDD (Cat3)
- 3G (DC-HSPA+ Cat 24)
- EV-DO Rev. B
- 1x Advanced
- TD-SCDMA
- GSM/GPRS/EDGE NFC.
Multimode/Multiband Means Worldwide Coverage.
• Support for multiple radio frequencies: Mobile broadband technologies are growing increasingly complex in their implementation. LTE is currently being implemented in over 40 diff erent radio frequency bands throughout the world. To complement its wide range of modem standards supported, Qualcomm has designed the Snapdragon S4 Processor MSM8960 CHIPSET platform to <<< address all commonly-used frequencies (from 700–2600 MHz) and bandwidths up to 20 MHz>>>, allowing its customers to address any mobile network opportunity whether the simplest single frequency implementation to the most extensive multi-frequency global mode, whether 4G, 3G or 2G.
-----------------------------------------------------------
Based on the document the chip can handle all LTE Standards, but it depends on his "advanced, programmable architecture"....as written there and how Motorola / Sprint implemented this, maybe they reduced LTE only to one Standard.
I don't have LTE in my area and so I cannot test this.
That's possibly right.
Something else:
If I remember correctly, somewhere in this forum have been said that for CDMA the internal Sprint "ID"(?) is used.
Maybe that's also the reason why I cannot connect to LTE in my area.
The phone is trying to "login" with the Sprint ID and this of course won't work.
The ##DEBUG# menu wasn't helpfull. It shows frequencies for american standards and not for GSM/WCDMA.
Also the LTE menu is also not very helpfull, it doesn't show frequencies at all.
Any News on this topic?
Maybe one of the developers can give a statement?
Yesterday I tested a LTE compatible SIM card.
My Bro has a Samsung Galaxy S4 with 4G/LTE in my area.
So I've put his SIM-Card into my Photon Q and set LTE only.
I had no luck, the Phone couldn't register into the network for this SIM.
I guess either it has the wrong frequencies or LTE is for inbuilt "SIM" (Sprint SIM?) only.
The latter. LTE is configured only for 1900 MHz which Sprint uses.
LTE is configured only for Sprint's frequencies, however, it supports the United States frequencies of PCS blocks A-G. The G Block is Sprint's current LTE channel, and they may deploy it later on Blocks A through F, depending on if they own the spectrum in a given market. The reason you see EU networks when the phone is in LTE Only Mode is most likely because the Phone still sees GSM signals, but will only connect to LTE ones from those GSM signals. Likewise, in the US, if you force LTE Only and then search for networks, AT&T and T-Mobile US will come up as the GSM carriers the Photon Q sees, rather than the LTE signals it sees.
Setting the Photon to LTE Only will not do anything for LTE in the EU. I suspect that if another carrier in the EU uses the 1900 MHz for LTE, the Photon Q will have no issues connecting to LTE in Europe. But until that time, be happy with HSPA.

Can this configuration theoretically be changed / other frequencies be added?
Only if you break BP security.

Sorry, what's that?
IIRC The only place with 850mhz LTE available is the Chicago market and currently no phones at all support it. :crying:
Not only does your phone need to support it, your PRL and cell-site does too...
Hi,
I'm new to posting on xda, been using it for advice for ages but this is the first time I haven't been able to find my answer. So I'm going to apologize if I've posted this in the wrong place or done anything else incorrectly right now.
I ordered an R7 plus from Taiwan and received it a few days ago. A great phone, i am entirely in love with it. I can put up with the bits of scattered chinese in the settings as i will be flashing cyanogen as soon as it's available. My problem however lies in the connectivity. I didnt know a whole lot about wireless data before ordering the phone, but what little I did know I applied to my research and found that all three variants of the phone should work on my providers network. I have the Taiwanese variant, which does supposedly support the 2100mhz, and 2600mhz frequencies, which i believe are bands 4 and 7, anyway, these two frequencies are the frequencies my provider uses. Rogers uses FDD with 2100 being up and 2600 being down. Yet in the phone settings when selecting which LTE band 4 and 7 arent options, there's USA Band (Im unsure what this really is, I assumed it was 4 because much of the us uses band 4), 6, 33, etc. And I havent been able to get LTE to work. The APN is configured correctly. All anyone's been able to tell me is that it should work. I can provide any more information you guys need, but any help would be greatly appreciated.
Edit: For more info- My provider is Rogers, i have also tried it on Bell (still only 3g), and Wind, which works the majority of Chinese phones and it didnt even pick up their network. Any advice would be great!
I have a few questions about this model:
Anyone know if there is a Global ROM in the works or can I put the normal Mi Mix 3 Global Rom on this model?
Anyone know what settings I need to set to allow this phone on to ATT's LTE network? I attempt to use the APN ATT Nextgenphone but it will not connect to that one. I have to use the Att Phone which it will connect but still it will not let me get anything above 3G speeds.
Any help would be greatly appreciated!
Thanks
LTE/Carrier
Before I purchased this phone, I checked all the sites for compatibility and what bands/frequencies AT&T uses for their LTE/4G networks. All of the sites stated that the Forbidden City model has all the bands needed to work with the carrier. Does anyone know how to get the phone to work with the LTE bands or what carrier in the USA will the phone work with the best?
Any help would be much appreciated!

it's got best all around LTE band coverage for AT&T in my area. Verizon isn't bad, just expensive. T-Mobile supports all the bands in my area but the quality sucks in my opinion. Sprint is obviously garbage especially for unlocked international phones.
