Will be posting this in the T989 Q&A as well as I am not sure which side of this is the best to ask:
I am currently using the Rogers I727R on bell. now bell's network can handle Dual Channel HSPA+ (42Mbps) Rogers did not so the speed on the SGS2 is max 21Mbps without LTE.
What I am trying to get at here is this, is it possible to modify the modem software to allow it to use that network as well as LTE? (assuming the internals are the same as the t989 with the exception of the LTE modem)
The final product being a device that does both dual channel HSPA+ and LTE.
No idea if this is remotely possible but thought I would throw it out there.

Noob question sorry. My buddy has a GT-I9020T (900mhz?) running on wind, he wants to change service providers to rogers (850mhz?). If i were to root his phone and flash the rogers radio onto it, would he be able to connect to the rogers network with a rogers sim? afaik the answer is no but i just want to verify before i give him incorrect information.
No the radio is also hardware based but from what I understand you'll be able to get 2G {Edge} on rogers but not 3G and on Bell and Telus it won't work at all
Sent from my Nexus S using XDA Premium App
That is correct, you will be able to connect to Rogers using GSM and only with 2g speeds. Forget about connecting with any network that strictly uses HSDPA like Koodo, as it will not work (not sure if Telus is the same). I've tested this myself - had to get rid of my i9020T because around my house Wind had a dead spot -_-
like the guys said, the frequencies are hardware based, so there is nothing you can do to change them. rooting won't help. you'd need to buy a whole new nexus s that has the correct frequencies for the Rogers network 3g bands.
I know LTE-A is better since its true 4G, but what I'm curious about is LTE a huge hardware difference to LTE-A? Would it be a simple software change to allow faster Bandwidth similar to how T-mobile increases their HSPA+ from 14>24>44 etc OR is it more of a major hardware change say like going to each tower and adding specialized Equipment
Sum it up LTE to LTE-Advance as simple as a Firm/software change or is it a tower upgrade?
Verizon could at any moment flip the switch and go full blown LTE-A or would it be another slow roll out of tower upgrades?
I'm guessing current LTE device will be able to connect to LTE-A but max out due to 1st Gen LTE modem limit
wikipedia (yea yea whatever) == "Backward compatibility of LTE-Advanced with LTE. An LTE terminal should be able to work in an LTE-Advanced network and vice versa. Any exceptions will be considered by 3GPP."

Hi guys not so sure if I'm posting in the right place but I was wondering if Australian sim card can work with the skyrocket?
Many thanks!
As long as its GSM, and your network is running skyrocket supported frequencies (gsmarena.com > search skyrocket) you should be fine.
Basically, if you have what's called a gsm carrier you're golden.
With that said, your carrier/phone service provider may not have LTE or even 4g (hspa+) capabilities, meaning 3g only.
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?
I do not know if this is allowed and if it is not sorry but it is not a best of thread. I have been having trouble getting good speeds since the switch and have tried numerous combinations but get crappy speeds like .11 mbs down and .12 up
I was wondering what works for you and what speeds are you getting.
Like I said this is by no means a best of thread I just thought this would help others like me who are having trouble getting good speeds on our phones.
Any downloads to the radios not listed in the radios thread would be appreciated.
And if this thread is off limits I am sorry. Just thought I would help us newbies out!!!!!!
Thank you
Jeff

What gives me a little pause here is that those settings and radio combinations will yield different results based on where you are located. Do you know anyone in your area with an HSPA+ phone who can run speed tests to compare your speeds against? It could just be that you're in an area with bad backhaul.
two important bits of info are missing what network type is your phone connected with (g e 3g h h+), and what radio are you using?

A good first step is to find some friend with a good t mobile hasp+ phone (like galaxy s2 T-Mobile or galaxy nexus for instance) ...See what speeds they're getting on T-Mobile data...If they're not getting good speeds on their phones, you'll never get good speeds obviously...Remember you're using a phone which was made to be used with AT&T....And from my observation most of those who use the SR with T-Mobile they get similar issues like the ones you're describing , t-mobile switched to the 1900mhz spectrum in some areas that would probably help a little, but obviously that's not something that you can do anything about...
If you really need tmobile service, it's best to trade your SR with a tmobile galaxy s2 , at least that I would do if I was in your situation,I don't like buggy phones or services...

It's a long thread but covers this issue pretty well. As far as I can tell there is no hardware-based reason a Skyrocket can't work on Tmobile as well as a dedicated tmobile S2.
I have been using a skyrocket on tmobile for a few months. I couldn't get better than 2G speed until I flashed a new radio and twiddled the apn settings. I get pretty consistent 4G now.
This is what I get using T769UVLH5 radio from this thread http://forum.xda-developers.com/showthread.php?t=1895400
Be sure to thank him:good:
I know you're getting different answers here but if you took an at & t skyrocket it means you have bands 850/1900Mhz for 3g ( don't even think about 4g lte at this point) while tmobl works on 900/1700/2100 3g bands. This means your phone is physically not capable of locking on those bands because it doesn't have them. All it's probably doing is sticking to the old EDGE network since it is a quad band edge.
Sorry to be the bearer of bad news

I do not believe that is the case. The skyrocket radio software limits the available bands. Loading a tmobile radio enables the required frequencies.
i727 freq's:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
4G Network LTE 700 MHz Class 17 / 1700 / 2100
Frequecy Source: GSMARENA

From what I've gathered the skyrocket has the same radios as the Hercules, it just has the added lte hardware. I am on 4.2.2 slim using the le1 radio. Still get random no signal dropouts but not as bad as the others. Think my ril and csc files are wrong so it looks like I have to flash a stock ROM to get them back. Anyone using a stock Hercules ROM?

I don't think our channel can do dual channel h+ where the T989 can.
for the others our phone has a penta-band radio it is physically cappable of talking to t-mobile on it's 3g,h,h+ networks just not with the att or rogers radios.
