i9505 question on hspa and 4g/lte - Galaxy S 4 Q&A, Help & Troubleshooting

Hi so I have the i9505 with me with omega rom v10 installed. I know that a lot of Canadian telecommunications companies use HSPA but as far as I know, Korean telecommunications companies use 4g/LTE and no HSPA. When I was in South Korea just a couple days ago, my phone would never switch to 4g/LTE and would only stay on HSPA. Is there a particular way to switch off HSPA manually and rather use 4g/LTE?

the problem with that is if you got no 4g you wont be able to get data

yea I know that but what I'm asking is if there is a way to make 4g/LTE a priority rather than the phone using HSPA. 4g/LTE is a lot faster in South Korea compared to the HSPA so I wanted the phone to stay on 4g/LTE rather than using HSPA since HSPA doesn't really exist in South Korea

Galaxy s 9000 with tmobile 3g usa?

Anyone here have the galaxy s 9000 euro version working with tmobile 3 g in usa?
I'm also interested in that. I'm about to buy a galaxy here in EU but I'm moving to california soon. There should be no issues however since the galaxy is a quad band phone
I looked into importing a HTC Desire from Tmo UK for use here on Tmo's US network -
Tmo europe uses 2100 band for 3g, Tmo US uses the AWS IV band (1700/2100) for 3G - i did a little more research and found that 2100 was the download side and 1700 for upload - and as Tmo here in the US told me my Tmo MyTouch 3G would work fine in europe, i figured i'd be good to go - maybe only have 3G speeds on the download side
got hold of a 2nd level tech at Tmo and he 'xplained it down't work that way - if the Tmo US network doesn't see both freqs (1700 & 2100) it will switch me to 2G data speeds
so answer is, it'll work for phone calls, but data speeds will be limited to 2G

I can confirm, I did a lot of digging myself and found the same thing. I'm from the UK but living in the US for a year or so. I was going to get a Galaxy S from ebay but realised they didn't have the 1700 freq so wouldn't get 3g with T-mobile over here ion the US.
My Iphone 3g from the UK only gets edge data transfer speeds here in the US as it too is missing the important 1700 freq...

Finally figured this out too after posting questions in different places. Found this article which had a very detail explaination.

One thing I'm wondering is if it is possible to flash the android radio version from a Vibrant on to an international Galaxy S to enable Tmobile AWS?
that question is best answered by someone far more knowledgeable than i am in software and android OS
i want 3g
I just recently bought the unlocked galaxy s to use for when I study abroad in Germany in the coming months. However, I am experiencing the very issue raised in this thread and have been searching high and low to find a solution to change the radio frequency to include both 1700 and 2100. Hopefully, flashing the firmware from the vibrant to the unlocked galaxy s will work, but I'm not experienced enough to even know where to start.

USA AT&T Galaxy Tab questions answered here

I created this thread because there seems to be some confusion as to the differences between the T-Mobile, Euro, and (soon to arrive) AT&T branded versions of the Galaxy Tab. I'm sure at some point enough information will exist for a proper XDA wiki entry, but for now, we need a thread for each variant with specs, and where possible, hack/flash options, including phone and data connections.
So this will be the US AT&T thread, where we can get the facts straight for those who wish to use AT&T as their carrier with a Galaxy Tab.
THIS THREAD IS FOR US AT&T GSM ONLY, DISCUSSIONS ABOUT CDMA (SPRINT, VERIZON, ETC) SHOULD BE IN ANOTHER THREAD!
Other carrier-specific threads:
US Tmobile Galaxy Tab flashed to make phone calls (currently phone works only, no 3G data)
(I would suggest to moderators that other non-AT&T and CDMA-related posts be removed or moved to a more appropriate thread.)
Alright, for starters, let me post the US AT&T frequency information, so that n00bs can be up to speed.
850 MHz GSM/GPRS/EDGE 2G
1900 MHz GSM/GPRS/EDGE 2G
850 MHz UMTS/WCDMA/HSPA 3G
1900 MHz UMTS/WCDMA/HSPA 3G
This should be helpful when we discuss the Galaxy Tab specs. I will be re-editing this post as new information comes in.
[future verified information can be placed here]
[reserved for FAQ]
[reserved for links as needed]
Actually, the SGH-I987 version that AT&T is getting has already launched. In Canada. On two carriers.
The Bell version has two model numbers on the back, the GT-P1000M (firmware is different, and presumably less crippled than what AT&T will release, hello sideloading), and the FCC model number of SGH-I987 on the back cover, so the internals are identical to the AT&T unit.
And you missed a few bands, any Galaxy Tab with a SIM card will work on 2100 UMTS as well as 900 and 2100 GSM/GPRS/EDGE.
AT&T should be releasing their branded version of the Galaxy Tab on the 21st (just a few days from this posting). If I understand right (this is where the value of this thread will come into play), the specs for the T-Mobile version are different in terms of the 3G radio frequencies.
IF this is true, then it would mean that if you plan to use AT&T as your US carrier:
You must run an AT&T branded Galaxy Tab
You must run a Euro-spec Galaxy Tab*
*specific procedure for this to work is unverified at this time
Price
At this time, the price for an AT&T branded Galaxy Tab will be $650 from AT&T. It will have two pay as you go plans--$14.99 for 30 days and up to 250MB of storage or $25 for 30 days of up to 2GB. This is similar to how they currently handle the iPad plans.
HOWEVER, as many people here on XDA-devs know, it has always been possible to take a GSM SIM and move from phone to phone, and provided that the frequencies are compatible, the services should carry over and the device change remains largely in the control of the owner. Of course, they can detect the IMEI at the carrier, but in most cases they are not blocking IMEI's. If your device has the right radios and frequencies, it should work. In the past, this has been the case with most devices.
So the question is: Does the Euro-spec Galaxy Tab have the same frequencies as the AT&T branded Galaxy Tab? It should, considering that the specs for the Euro version seem to reflect the same frequencies that AT&T uses.
In theory, getting the software right on the Euro-spec Galaxy Tab should be a matter of flashing a working cooked ROM to enable phone and 3G connectivity.
As of the time of this post, one or two people have managed to get a Galaxy Tab phone service working with AT&T, although I am unsure about 3G.
Again, the purpose of this thread is to clear up these questions, and keep it focused on getting a fully-functional Galaxy Tab on the AT&T carrier. Meaning both phone and 3G working as normal with any other device.
I can confirm that the European Tab works fine on at&t with full 3G and Voice dialing.
It is model GT-P1000
FCC ID: A3LGTP1000
I have been using it for the past few weeks and it seems to support all the required frequencies. It has operated in every mode including (G)PRS, (E)DGE, (3G) and (H)SPA
Stupid question then. Doesn't Canadian Rogers use the same frequencies as AT&T?
They sell Galaxy Tab too right? Does their Galaxy Tab have voice call capability?
I am interested in buying Galaxy Tab that could do 3G on AT&T and can make voice calls so I could use it as my phone ;-)

Interesting news... I bought an unlocked device in Kuwait City and it matches that FCC id number, but it had some Arabic apps loaded onto it, does this mean the euro and middle east versions are the same?
Also, how much of AT&T's network is is 850?? I didnt think the 3G would work back in the states... btw, my home is in the DC area is that helps.. Thanks!

The FCC docs actually say that the GT-P1000L, N, T models do support 850GSM and 850WCDMA(3G):
Type the device's FCC ID info in, (A3L is the manufacturer code for Samsung). Look at the documents in the 824.20 (GSM "850") and 826.40 (WCDMA "850") lower frequency ranges.
The actual test report docs list GT-P1000L and GT-P1000N and a clarification doc from Samsung says the GT-P1000T model is just a renamed L one.
This is great, it's exactly why I wanted to start this thread. SO, one person at least has a Euro-spec (GT-P1000) machine wortking with voice and 3G data on a US AT&T network.
Someone needs to post specs on the GT-P1000. Because right now, it would seem that the P1000 is the best bet for those who want to use FULL functionality on a US AT&T network.
My personal motivation for this thread is to get solid information on what model Galaxy Tab will have full US AT&T functionality (voice and good 3G data connect), and HOW to achieve that (choosing the right Galaxy Tab and flashing the right ROM). Once this is nailed down, I'll buy one. I just need to know which to buy and what to do to it.

Not FULLY working on at&t's 3g network. The 850 band for 3g is still missing and 850 is their primary 3g band and it's slowly replacing the 1900 3g band. The reason they changed was because the 850 3g band can cut thru walls better and give you a better 3g signal. I remember when my area had only 1900. My 3g sucked. Very spotty unless I was outside. I instantly noticed when the 850 upgrade took place. Solid 3g even in the darkest areas of my basement @ work. There will be an unlocked 850/1900 3g band version on the tab but it looks like it was pushed off until early 2011. Probably because they knew they would never sell any of the current north american models with the 850/1900 3g bands (bell, rogers & at&t) For what it's worth, you can pre-order that version here:

Who said at&t's primary 3G is 850Mhz?
That is just false information.
Their primary is actually 1900Mhz and they are beefing it up with new 850Mhz towers, not instead of current 1900Mhz existing in infrastructure.
Places who only recently got 3G service might be on 850Mhz but all those who got 3G up until 2 years ago are all 1900Mhz with the addition of 850Mhz.

Yea this article and all the others stating the same are copying the same wrong source.
At&t never said they will be replacing 1900mhz with 850mhz...they said they will be ADDING towers and expending their network on 850mhz.
Here in the sf bay area the netwrok is mainly 1900mhz but they are ADDING new 850mhz towers so now we get mixed frequencies in places where signal was bad. They are certainly not removing 1900mhz towers.

This thread encapsulates my concerns exactly. I want to use my tab as a phone, and am on ATT, so will wait to see how to best implement this agenda before purchasing anything. I have a couple of concerns:
1) I think that the Galaxy Tab forum should be split amongst various carriers, since future roms and such will likely be device specific.
2) Now that more information is coming out with regards to the Nexus s and Galaxy 2, I am wondering whether I should hold out. I do want a large screen, but the development community/google support for the next Nexus phone is hard to pass up... maybe I will buy both!
Regarding splitting up the forums, I don't think that's a good idea. We tried it for the Galaxy S models and it is something of a clusterfuck, and not as much knowledge is being shared IMHO.

[Q] Unlocked Nexus S with 3G network

I want to get a Nexus S for myself, the unlocked without contract one, because I would like to use it in my home country (Malaysia).
So I would like to confirm one thing before I proceed:
I saw this from BestBuy forum FAQs:
Will an unlocked Nexus S work with carriers other than T-Mobile?
Yes, but it won’t run on 3G with all carriers. Speed and power will be reduced on non-3G networks.
Is that means that even though Nexus S did support the 3G band of my home country, it won't run on the 3G network?! Means that I can't use the 3G in my home country?
Anyone have answer for this? Anyone tried buy N1 and got the 3G working in country outside US?
gotta be 1700/2100 MHz i believe
Wont' work. Malaysia uses 2100mhz band for 3G.
The Nexus S on T-Mobile uses BOTH 1700/2100mhz AT THE SAME TIME for 3G.
It will work fine since the 3G band in Malaysia is 2100MHz and the Nexus S supports those bands.
I had the Nexus One (T-Mobile Version) in Thailand and it worked perfectly fine on 2100MHz 3G. My N900 worked as well.
Don't listen to nxt or slowz3r they have no idea of what they are talking about.

You wont have a problem with most 3g phones in Malaysia - most of the rest of the world uses standard frequencies and the nexus s and nexus 1 work just fine.
If a phone works in Europe then it'll be fine in malaysia, and indeed most of the rest of the world.
Most of the noise on here is from people in the US where there are some weird frequencies being used... you can only use 3g on T-Mobile there -at+t uses different frequencies, and sprint and Verizon use a completely different technology.
Thank you for all the useful replies!
Got the answer. Thread Closed.

[Q] Feedback required from Virgin Mobile Canada Galaxy S4 Users

Hey folks,
I am currently using an unlocked S4 from Wind Mobile on the Virgin Mobile network. It is technically the T-Mobile variant - SGH-M919V.
In comparison, the Virgin/Bell S4 is the SGH-I337.
My phone usually stays on LTE but it tends to revert to 3G in some areas, but never on 4G or H+. I had thought that the bands were compatible on the virgin mobile network, which brings me to my question.
Does your S4 ever revert to 4G or H+ when not on LTE? If that is the case, I am thinking of trading my Wind S4 for the Virgin/Bell S4.
Appreciate your feedback.
Thank you.
I'm pretty sure the M919 should fully support the 850 and 1900 MHz UMTS/HSPA bands, also you'd never see 3G or be able to do voice calls and texts without them.
I just got my SGH-I337M from Virgin yesterday and it definitely reverts to H+. So far it seems that it reverts from LTE to H+ after the phone has been sitting a while, and then if I start using the data it will kick up to LTE (probably doing that to save battery instead of keeping LTE on all the time?).
Who knows what could be going on with your unit. That is a Wind unit right? Maybe the software is different. One thing I know is that ROMs can show 3G/4G/H/H+ differently. Have you done a speed test while it is showing 3G? If it is true that you are falling all the way down to basic 3G/UMTS and not getting HSPA/HSPA+ then your speeds should be limited to less than 0.5 Mbps I think.
Thanks for the quick reply.
I managed to run a couple of speedtests when not on LTE. And they were around 2 Mbps down and 1.5 Mbps up. I don't think those are necessarily H+ speeds. But it's decent enough. Maybe then the reason I am seeing 3G is because of the way the ROM chooses to display non-LTE connections.
I double checked the supported bands, and it is true that the Wind S4 (T-Mobile variant) not only supports all the bands that the Bell/Virgin S4 does but the additional AWS band as well.
Is there a way for me to force the H+ connection on the phone, just to see that it works? Or should I possibly flash the modem/radio from the virgin/bell ROM?
Open up the Testing Menu, go into Device Info and see what it says for Network Type.
Make sure your wifi is off and hit "Run ping test" as few times and look at what it changes to.
HSPAP:15
HSPA:11
HSUPA:10
If you see these then it's fine, just icons are different.
Solved!
Okay,
I did a few things to verify that despite the phone showing 3G, it is in fact on 4G or H+ when not on LTE.
I went into ServiceMode by entering *#2263# in the Phone Dialer.
I forced non-LTE connections by changing the automatic preference to WCDMA 850 and WCDMA 1900 respectively.
These are the 2 bands that are 4G or H+ for Bell and Virgin Mobile Canada.
Then I ran speedtests to a close by server and got around 7 Mbps down and 3 Mbps, which are definitely 4G/H+ speeds.
Also, following @ChronoReverse advice, I found that the network type was in fact HSPAP: 15 and HSPA: 11 (screenshots attached).
So, in conclusion I can rest my obsessive personality and accept the fact that the phone is in fact capable & is running on 4G networks. It's a ROM thing I suppose.
Or in other words, the Galaxy S4 from Wind Mobile (or T-Mobile) is completely capable of running on Virgin Mobile Canada, Bell Canada, Rogers networks with full support of LTE and 4G/H+.
Embarrassed to say what a small little 3G icon does to a person these days!
Thanks for all the help!

Note 10.1 2014 USA Verizon LTE

Spoke to someone who I trust on the inside and was told Verizon has the Note in hand & is testing it.
They are modifying it and working the kinks out. Conservative estimates are that it will release in February 2014...but the absolute latest is April 2014. These are conservative estimates and it could possibly release earlier.
This is good news. If Verizon is testing it, that means they have a version with 700MHz LTE (and likely 1700/2100/2600 as well).
Currently on the fence about buying the European version with its limited LTE capability. Please keep us updated if you hear more!
don't mean to hijack the thread but dont feel this warrants a new thread...
Will the European Note 10.1 LTE work on all AT&Ts bands or will it be limited?

It will be limited on LTE. AT&T uses 700MHz and 1700/2100MHz for LTE. I'm unsure if they use 2600MHz as well. The three Canadian carriers use 2600MHz for their 150Mbps LTE Max network, which is has limited coverage in major cities.
The European P605 supports 850/900/1900/2100/2600.

What does limited mean?
I'm not entirely aware of how AT&T's LTE setup is, but according to reports there are some areas where they are using 1900MHz and 2100MHz for LTE signals. The note will have connectivity in those areas. However their main frequencies are 700 and 1700 I believe, so in most areas you wont see an LTE signal.
