[Q] 4G LTE - General Questions and Answers

Hi, just got a device in Europe and found out it is 4G.
Read something about not being able to use it in the US.
What does that mean, that the phone won't work at all, or that it has to do with mobile internet connection or a wifi connection?
If this is a problem, is it possible to fix this with a new rom?

The phone should work in the US but not on 4G LTE due to the different operator frequencies.
In the UK we use 800, 1800, 2600, 3500 and 3700MHz where as in the US they use 700, 850, 1700, 1900 & 2500MHz.
So it should work on the 3G/HSPDA bands but not LTE unless it uses some kind of global LTE chip.

Help - want to buy Captivate for UK?

Hi everyone. I’m currently living in the UK and I’m interested in the Samsung Galaxy S (i9000). Unlike in the USA, there’s only one variant and its quite expensive. Much cheaper in the USA! So I’ve been looking at the Samsung Captivate, AT&T’s Galaxy S variant.
Network
Samsung Galaxy S –
2G Network
GSM 850 / 900 / 1800 / 1900
3G Network
HSDPA 900 / 1900 / 2100
Samsung Captivate –
2G Network
GSM 850 / 900 / 1800 / 1900
3G Network
HSDPA 850 / 1900 / 2100
2G is exactly same band, but 3G is only 50MHz difference.
Will both 2G and 3G networks work fully in the UK?
Software
Am I correct in thinking I can remove the AT&T bloatware by flashing a custom ROM?
Can someone please suggest a good, fast lag-free 2.2 Froyo ROM?
Android Market
Am I correct in thinking I can use Market Access to change US market to UK?
Thanks for help in advance
you are confused on the 3G bands.... "only 50Mhz difference" statement is meaningless - if bands are not exact, then it won't work - period.
Having said that, the captivate will work in the UK - the 1900/2100 bands are 3G in US (ATT) and UK. You will get 2G and 3G.

Thanks for that.
What about the android market? Can I change it to UK using "Market Access" app?
Also, seeing as for 3G the first band is different (900 vs 850) will it have any affect on my 3G network connection?
The Captivate is a World Phone, meaning it will work around the world. If one 3G band doesn't work, you have 2 others, which you have already been told will work just fine

Yes, you should be able to use the Market Access app, but it takes a carrier code, not a country code. Using the phone with another SIM may set it automatically.
As for bands - you will probably find some areas where 3G is offered on a band you don't have - it is possible, but shouldn't happen any more often then if you had 900 on the phone. I took my iPhone all over EU - it was an ATT iPhone, and it worked fine with 3G. The Captivate should do just as well.
Thanks for the help guys
Not only can you flash custom ROMs, but the SetiroN kernel lets you flash regular Galaxy S ROMs onto the Captivate. If you look in the development forum here, you'll see that there's basically only one native Captivate custom ROM (Cognition); the rest are all Captivate-flavored Galaxy S adaptations using SetiroN (or its predecessor).

[Q] Samsung Vibrant 4G SPECIFICATIONS

I know the original vibrant was a pentaband phone, supporting AT&T's 850/1900 networks as well as t-mobiles 3g networks....
Can anyone confirm the 3g bands on the new Vibrant 4g?
Will there be fast 3g 21mbps for 850/1900 on the modem chip also? ( or 4g whatever you want to call it, in my book its just faster 3g..)
someone enter the debug screen and check which bands are available...
cheers!

HSPA+ 21 only works with T-mobile, AT&T doesn't use an AWS band, in this case is 1700/2100Mhz.
Someone may have been able to 'trick' the vibrant into using a basic UMTS band on AT&T, but I never heard of it, let alone heard that the Vibrant supported AT&T 3G. The Vibrant has GSM.support for them (2G), I haven't seen anything else.
Where's the supporting documents that people have been getting At&t 3G with a T-Mobile Vibrant?

Trust me.... I'm using a vibrant on at&t with 3g. It does support the wcdma 1900 band. There is alot of evidence of this...heck engadget made a post about this... google it!
Edit: What I was trying to ask is if the galaxy s 4g supports the 1900 wcdma that the original vibrant supported....

That would work....hopefully the galaxy s 4g can be unlocked the same way the previous galaxy s phones could.
In my research I have found that 4G is not backwards compatable with 3G. Someware I read that companys are putting 3G and 4G chips on the new 4G phones to bridge the gap between the 3G chip ability to handle voice and the 4G chip being able to handle data. I can't say for sure if SGS4G has both chips. It's a know issue that the 3G SGS misses calls when connected to a laptop because It does not handle data well in combination with voice. That's why I upgraded to the 4G. I don't think Its going to make a lot of difference until TM gets their HW in place with a backbone that can support it.
Samsung Galaxy S 4G 1900 MHz WCDMA
I bought my Samsung Galaxy S 4G at a T-Mobile store in San Francisco. I subsequently upgraded it to the latest firmware provided by T-Mobile using Samsung Kies.
I usually use WCDMA only mode because GSM causes awful buzzing sound when I use it in my car (I have a FM transmitter connected to my phone).
Anyways, I was curious to see if I'd see AT&T, so I searched for network (still under WCDMA Only mode), and it found both AT&T and T-Mobile.
I pressed *#197328640# in the dialer, and then went to the debug screen/band selection to look at available bands, and it actually does have 1900 WCDMA.
It shows
GSM 850, 900, 1800, 1900, WCDMA 2100 (FDD I), WCDMA 1700 (FDD IV), WCDMA 1900(FDD II).
I don't know if AT&T SIM would work since my phone is locked but I can report back once I get it unlocked.
EDIT: Reading an old post of mine, I realized that my memory played a bad trick on me. My tests DID work on 1900 WCDMA and DID NOT work on 850 WCDMA, just opposite to what I wrote earlier in this post. --sorry

I don't think it would work. For reference, here is a side by side band comparison between my Vibrant (tested 3G on AT&T) and my coworker's SGS 4G (locked, untested).
The essential band here is the 850 1900 WCDMA, but the "overflow" 850 WCDMA is missing and I couldn't make it work anyways (I'm in Houston, maybe it is not switched on here).
My understanding is that AT&T usually uses 1900MHz for 3G, and in certain cities where they don't have enough bandwidth in 1900 MHz like NYC and SF, they use 850MHz.. so you could still get by with only 1900 MHz, no?

Yep, thats what I have heard as well. Now one thing of note. When I tested my Vibe, it only worked on the 850 1900 WCDMA band. Could not make it work on the 850 no matter how hard I tried. I'm in Houston for that matter and maybe this 850 WCDMA is not enabled here.

I'm currently unlocked on AT&T and i'm on 3G. I ALWAYS have an issue with upload speeds, but otherwise download speeds are just fine.
I attached four photos, of the available bands with my CURRENT galaxy S 4G unlocked on AT&T.
Also, a speed test I ran. That download speed is WAY higher than average because it was taken when the network was under the lightest usage possible, late at night.
Oh wow, over 5Mbps download on AT&T?
Are you on AT&T's 4G (HSPA+) or 3G?
I'm supposedly on T-Mobile 4G (my phone shows 4G when I download/upload), but I don't ever get 5Mbps. I get usually something around 2~3Mbps down and 1Mbps upload. I'm in the Bay Area.
I went into phone debug page, and one of the screens says HSDPA[0], HSUPA[0]. It also says network status: HSDPA (sorry I don't have the exact info on me right now).
Am I really just on HSDPA, not HSPA+? Is there a definite way to find out what my phone is using? Thank you.

Technically I'm on HSPA+, though this phone doesn't even cover all of the "necessary" bands.
Look, to edit what bands you're on go into the market and download SGS Tools.
Then, go into the first line (Secret Codes) and hit Band Selection.
I'm on AT&T so I'm not sure what bands you need, but you can manually select them in there.
To check the band you're on, go to GSM Status in the "Secret Codes" page again.

Oh I know I'm on 1700/2100 MHz because that's the only frequency (AWS) that T-Mobile uses for WCDMA/UMTS/4G/3G.
I downloaded Phono, and it says Network Type is HSDPA. Shouldn't it say HSPA+? I'm just wondering if there's an easy way to tell if I'm really on 4G (aka HSPA+) as opposed to 3G.
I actually messed around with debug settings last night so I'm worried that I screwed it up....
Thank you!

Which debug settings did you change?
And as for Phono (which I've never even heard of/used until now), my phone says HSDPA as well, which, quite frankly, makes no sense. I guess you can technically get speeds of around 5MBPS on HSDPA but it's not typical.
You should easily be able to tell whether you're on HSDPA or HSPA+ with the 4G/3G connectivity icon. in your status bar.
Now, I'm no expert, but hopefully that answers your question.
I played around with GCF settings. When I go into debug mode, there was something about choosing Rel.6 or Rel.5 or cancel settings.. And then also, if you do *#3214789#, you can enable/disable GCF Mode.. which I have no idea what it is about....
Thanks!

Hmm...that's awfully strange.....
I can't find anything about it anywhere....
Try restoring using ODIN yet?
I mean, if the phone is that messed up since you messed with that setting.
I put my friends att sim in my unlocked sgs4g to test and the 3g sign came up by the bars as well as the att operator logo didn't really test out speeds but im guessing that the 3g sign wouldn't have came up unless it was really picking up that frequency.

[Q] Does this phone support HSPA+ on 1900Mhz??

Well after moths investigating on internet and different carriers in my country I can solve this, the thing is here we have HSPA+ "4G" i'm with Digicel right now but the thing is I still getting 3G, moreover settings>about>status>mobile net type says HSDPA and I've confirmed they use 1900Mhz for 4G
Customer service as always don't even know what all of this things are so this is my last resort to solve this mystery. Is the carrier or the phone??????
thanks in advance
**delete**
Thanks for the reply but the post don't really help me because Digicel only use 1900 as I said I got 3G but not HSPA+. When I enable/disable wcdma 1900 is it turns to 3G/edge instead of "4G"

When choosing a phone, what frequencies will work on this network?
· Our 4G network will work well with any 3G+ handset which supports 2100 MHz.
This is off of one of Digicel's websites.

Sorry for don't mentioned this before but I'm with Digicel Panamá, here the only available bands are 850 and 1900 and they only use 1900. However I tested with 2100 only enabled and doesn't work.
This phone can use 1900mhz too, for some reason I only get 3.5G instead 4G or H+ symbol...
I am with Cincinnati Bell and have never been able to get my phone on 4g (except when I was in Chicago). I have spent hours on the phone with customer service, reading forums, posting questions and I still to this day only get 3g. There is something odd about this phone using another (smaller) carriers 4g (hspa+).
However, I know that there are a lot of people that use Simple Mobile with our phone and 4g is no problem... so idk

[Q] Motorola RAZR HD XT925 LTE Frequencies

Hey Guys,
I have a Motorola RAZR HD XT925 which was sourced from Rogers Canada. I was wondering how I can check the devices LTE frequencies? Is there any engineering code and/or menu that would assist with this? This device apparently supports LTE 800 / 1800 / 2600 or LTE 700 / 800 / 1700 / 1800 / 2600 according to GSM Arena. I am wanting to use the LTE 1800MHz frequency in Australia, though cannot get it to connect.
I have tried the following:
Searching for networks manually / letting the device select them automatically
Toggling between 3G only and Automatic (4G/3G/2G)
I definitely have the correct APN settings configured (for Telstra in Australia)
Data is enabled, the SIM card connects to 4G in another mobile
Any assistance would be appreciated, in finding out which LTE network frequencies this device supports.

XT925: (international)
Secondary Cellular Networks: LTE700 (B17), LTE1700/2100 (B4), LTE1800 (B3), LTE2600 (B7), LTE800 (B20)
From what I've read, B3 is Australia's LTE band, so it is supported, but it might be turned off in roger's radio.
Have you tried installing the firmware for Telstra? It's available here: http://sbf.droid-developers.org/van...25_A045_WIG149790_Service1FF_fastboot.xml.zip from this thread: http://forum.xda-developers.com/showthread.php?t=1943879 Maybe switching to your provider's firmware will fix the LTE issue.
Hi
Can you please provide an update. Did you manage to flash the Testra fw and latch in to the LTE 1800 band?
Coz i would like to buy a phone and do the same thing as you. I would not buy if you did not suceed.

Hi. This is a good source here in Australia. Hopefully is updated and current. http://whirlpool.net.au/wiki/mobile_phone_frequencies
Note, however, that LTE is really new here and not yet well implemented. I live in Sydney, but I'm outside of the LTE network at home. I'd have to travel closer to the business district to get it. I think its implemented around the airport as well. LTE is still a work in progress and Telstra is ahead of the game with the other telcos, but you're going to want to be able to connect to their "Next G" or 3.5 G to fallback on otherwise youre going to get 2G.
In any case, you want to make sure your APN settings are correct as well. There is loads of misinformation about that. You can have Telstra set them for you (or at least it worked on my Galaxy S2, haven't tried with this phone since I got it from their store). Try this link and see if it the correct one: http://www.configure.telstra.com.au/telstra/index.jsp
On my Galaxy S2, I had read lots of documentation and had things working but found that after going through a Telstra automated thing (I think the above link), that it set my APNs for me and I ended up with better speed and signal.
Just found this from their site as well concerning their 4G and 3G frequencies: http://www.telstra.com.au/mobile-phones/coverage-networks/networks/
The 2100 frequency on their 3G or NextG (3.5G) may have been turned off at this point; I don't remember. They may still be using it for legacy phones and people on bring your own phone plans but I beleive they had wanted to either shut it down or sell it to another carrier. I don't recall that my SGS2 got 850 ... I just noticed there's tabs on the Telstra page that explains their coverage. Click on them and that's more accurate than what I just typed
I suspect your problem is that you may not be in an LTE covered area. Either that or its your APN settings. Let us know how it goes.
EDIT: Sorry, I didn't read your post properly that the SIM works in another device. If it isn't your APN settings, you can take it to a Telstra store and ask them if they know what the problem is. On occasion they do know what their talking about. You can point them at this web page if need be and it might encourage them to look a little deeper:

Telstra's 3G 2100MHz network was part of 3GIS, an agreement between Telstra and VHA, which ended on August 31st. Telstra still uses the 3G 2100MHz network frequency, it is actually part of their Next G network now, they however do not advertise this, as very few sites are still using this network frequency, and it is far more important to have a device that supports 3G 850MHz. Telstra lost quite a few 3G 2100MHz sites when 3GIS closed, although all of the areas would have had 3G 850MHz anyhow, so it was not really a big deal.

[Q] HSPA+(HSUPA) on other than T-mobile?

I thought I can connect my 4GS onto the other UMTS network, but its max was HSDPA:9 (HSDPA:8 in JB).
Other phone such as Photon Q didn't have problem in connecting with HSPA+:15
Do I have to manually enable something? I believe this phone's potential is better than this
My carrier is using 2100MHz band, and my baseband ROM is a new one.
Is this info relevant : ?

If your carrier is using the 2100MHz frequency, this phone should have no problem using HSPA+ with it. When I travel to China, I use a China Unicom SIM in my MT4GS which enables my phone to use their 2100MHz HSPA+ network without any problem. Back at home in US, I use T-Mobile SIM.

Thanks, I don't know what causes this...
So, you are seeing H+ (HSPAP:15) right? All I can see with various ROMs are only 3G and H....
Do speed tests, symbols don't always mean what they say after all
Sent from my Nexus 4 using xda premium
just tested: only around 3Mbps whereas other hspa+ phone got 9Mbps...
Is there any hidden menu to tick this on?

The stock ROMs are configured by HTC/T-Mobile to display 4G when it has a HSPA+ connection. Other ROMs, however, will display 3G or H (depending on the ROM) for HSPA+. So, if you see 3G, H, or 4G, they are all HSPA+ connections. This phone operates data in the G (GPRS), E (2G or EDGE), and 4G/3G/H (HSPA+) modes. Depending on the carrier, it can perform up to 14Mbps HSPA+ but of course, you would rarely see that fast in the real world. It does not operate at the 21+ or 42+ levels of HSPA+.
I'm on a stock-based ROM (Miktouch), when I'm home on T-Mobile, I see 4G. Also, when I'm in China and connected to China Unicom, I see 4G.
I've never seen "H" on this phone, it always shown 3G or 4G (using stock ROM, just de-junked and rooted by myself)
IIRC speed test results, I had best down speed exceeding 14+Mbps on Wind in Vancouver and Toronto areas, but in US it almost always was 3G only (but then I was usually outside any large cities).

Thanks for the input, if you are using non-stock rom, still would you let me know what the following says in the most normal case:
setting - phone - status - mobile network type.
In my case, it's HSDPA:9, which seems obviously non-HSPA. Other phone shows HSPA+:15 or HSPAP:15.
Am I missing something, or HSDPA:9 can be also considered as a decent HSPA+ ?
I'm kinda downshifting toward MT4GS recently as I love its small form factor, but somewhat at a loss due to this limitation, thanks.
