So I have heard, but can anyone confirm this? Mobileplanet is apparently saying otherwise:

Oh NOs! But I'm kinda confused at this 850 and 1900 AT&T thing. Will the phones hardware just be like "Nah, son. Too much bandwidth."

Transferred to AT&T:
to sales... asked for tech support... sales person got me an answer which was "yea.. it's compatible..." "really? are you sure? I don't think you all offer 3g coverage in this frequency range" "oh it's not a phone you bought from us?" "yes I said that already, can you transfer me to tech support" "oh let me transfer you to customer service." "yes that'd be great. thanks" "i'd like to personally thank you for calling AT&T. did you have any questions today?" yes. how are you employed? CS Reps unavailable this late in the day.
Damn. Oh well.. I use T-Mobile anyway... so I didn't expect fast or good or stable or acceptable coverage of any kind.

my S730 is due to come today..I guess it will be going back....why did they make a device with no 3G connectivity in USA?.....mobileplanet is going to get a lot of returns!

Because it's not a device for the U.S.

No US 3G or GPS on S730
I spoke to On The Go Solutions prior to ordering the "US released" S730 product and they stated that 1900Mz UMTS is supported by the unit and cautioned me that one must be utilizing AT&T's network to use the feature.
I ordered the unit only to find the statement is incorrect - only 2100Mz is supported; thus no US UMTS support.
On The Go Solutions has offered to take back the unit.
I note that the ambiguous "UMTS supported" statements on several US vendor web sites have been changed to unambiguous "2100Mz-only UMTS supported" statements.
Whereas there is NMEA GPS data on comm 4 (8 bit, 4800 baud), the data does not appear to contain any useful information. No actual satellite data is provided, even though I have left the unit outside, with an unobstructed view of the sky, for over an hour.

S730 Gets FCC clearance
http://www.smartphonethoughts.com/n...n-of-the-htc-s730-gets-the-fcc-clearance.html
S730 received FCC clearance for the US. I wonder if this helps us.

Yeah, saw that. This is model WING200, mine is model WING220. Wonder what the difference in hardware is.

WINGS220 is the modelID for single band WINGS. Maybe the diversification is only done by software configuration (e.g. NV items). See my thread on Radio ROM dump where I explain how to dump NV items. Someone should compare them.

3g wont work in the states, even on ATT. I see mine try from time to time but it always ends up back on Edge. T mobile is rumord to be working on a 2100 band 3g network but no real word on it yet.
I would love 3g but I dont really miss it either. Edge is fast enough and I am a heavy data user, I only notice issues when its trying to reformat a website that was not made very well.

Okay this may come as a dumb question. I have T Mobile and this phone has the Bands such as 850 and 1900 so will this phone work in the states?

Negative, theres speculation in other threads that depending on the chip version in the phone it can be unlocked through software tweeks but at the moment it is just speculation so it will not work in the states.
If the American version releases you bet that will work on 3g. As of now our phones use the 50, 900, 1800, 1900 for voice communication and GPRS / EDge while using 2100 for 3g. T-Mobile has been working on deploying a 2100 band 3g network so it is possible that it might work on your phone eventually in one of their markets.
But as of now unless your in an area where they have it set up, or we figure out what the chip is and see if changing one of the settings wil enable these 3g frequencies for the states its a no go

Okay so i have done some research and from what i have read the phone will work in the states utilizing GPRS/EDGE. I have read Forums with people who live in the states and have this phone. Now the one thing is that you wont be able to use the 3G stuff which is fine by me because I currently have a Excalibur which doesnt have it anyways. I am still a lil confused because i get all this different information from people saying that you wont be able to use the phone and others that say you will. Someone help clear this up for me please !!!!

yes, you can use the phone in the US. i am using it here in San Diego, CA. You just wont get 3G data speeds, only Edge

How to get an X1i onto AT&T's 3G network?

So I've done my best to scour the seemingly millions of posts on this site, and I've found lots of useful info. What I really need is a "ROM" or "patch" or whatever you'd call it that will get my X1i onto AT&T's 3G network. I live in the Florida Keys where we have both 3G and Edge networks. For what ever reason my phone will always get on the Edge. While in Atlanta in May I was all over their 3G in certain areas. So I know my phone will use 3G, just not where I live. Any help would greatly be appreciated.

I am looking for this fix too. Hopefully in a ROM form.
I have the X1i but my carrier (Rogers/Fido) would work 3G only if I ha the X1a, would the X1a ROM be able to fix that?

No, ROMs won't control or overcome the limitations of the the physical hardware.. if you have an X1i (900/1900/2100) it will not be able to work no matter what in areas that require the 850 Mhz band.
AT&T has some 1900 Mhz 3G areas, but it is spotty as best. Canada used to have some 1900 Mhz 3G test areas in GTA, but Rogers has switched to 850 Mhz/1900 Mhz dual bands almost completely.
You're kind of out of luck if you have an X1i in North America.

Yea, it just depends on the area. In NC, ATT 3G is deployed on 1900MHz, but in other states where ATT has 850MHz, they may deploy 3G on the 850MHz band.

this may sounds stupid.... but you can move to the area that has 3G signal... that way you will get 3G in where you live
otherwise... what lazyjai said sums it all....

I have that problem as well...
I have an X1i and I cannot get it to go into 3G for the life of me! My fiance who has ATT as well has 3G all the time (he has a simpler phone lol) not fair... every now and then itll go into 3G for a few seconds at the most, then back to EDGE.
Have you found a fix to this yet?

If you have updated to the latest and greatest @ R3....try reflashing the device to the original R1....when I flashed to R3 edge was my primary signal...has to do with what they changed in the rilphone.dll...

I have no idea what that means, Im not that technically inclined, but I'm not totally stupid. I just don't understand all the terms and such.... I can research it though! I would really like 3G, as I'm sure the thread starter if he hasnt gotten it already.

As lazyjai said, you can't get an X1i on ATT 3G in north america. It's not a software thing, its a hardware thing. The X1i does not have the parts it would need to run on 3G in america. Thats why the X1a was made with american 3G parts. X1american (X1a) vs. X1international (X1i). So, there is no way to make it run ATT 3G in america (This includes roms, cabs, etc...).

Incorrect....
◦GSM/GPRS/EDGE 850/900/1800/1900
◦UMTS/HSDPA/HSUPA 900/1700/1900/2100 MHz
◦UMTS/HSDPA/HSUPA 850/1700/1900/2100 MHz
X1i will work on these frequencies....so if the 3g or higher signal is available in your area it will use it...if not then you are stuck on the edge frequency...I know in Orlando/surrounding area's they are upgrading the network so it may be readily available shortly....

You can flash to an earlier build of the rom...but I would suggest hardspl, then flashing to 1.11.25.76 radio....there are plenty of tutorials on here for both procedures...p.m. if you need assistance....

theres 1900+850 band inside major cities in the U.S atlanta , miami, san fran , LA , NYC , etc , you basically can use 3g in these cities but most non major cities just have 850

Guys there is NO fix for this.
AT&T has deployed their 3G network in the US on the 850MHz and 1900MHz bands. Depending on the area, both of these 3G bands, or either one maybe deployed. I have an X1a. In NC, AT&T only has a license for the 1900MHz band, for example. When I was in Baltimore, I was using the 850MHz 3G band.
The X1a support 3G frequency bands - 850MHz/1900MHz/2100MHz - ie. there is a hardware power amplifier for these three bands ONLY.
X1i - 900MHz/1900MHz/2100MHz - ie. there is a hardware power amplifier for these three bands ONLY.
Physical hardware limitation.
If your area has 850MHz 3G and you are using a X1i, you will NOT or EVER get 3G on the 850MHz band.
This has been discussed ad nauseum. If there was a fix, I'm sure the brilliant minds at XDA would have found it already.

[Q] GT-i9305 and 3G 1900MHz

Hey!!
Can someone help me with a question? I live in Canada and I'd like to buy the GT-i9305. The biggest mobile carrier in here uses 850 MHz and 1900 MHz for 3G service, but just the 1900 MHz network has DC-HSPA+ with download speed up to 42Mbps. The 850 MHz network uses HSPA+ download speed up to 21Mbps. I'm pretty sure that i9305 does not has 3G 1900 MHz. And that's why I need your help!!!
Can someone try select WCDMA 1900 option into BAND SELECTION menu, please? To do this just dialing *#197328640# and then select UMTS -> Debug Screen -> Phone Control -> Network Control -> Band Selection -> WCDMA 1900.
But if you open the Band Selection menu and can't find or can't select WCDMA 1900 option on the list, that means the i9305 does not has support for 3G 1900 MHz. So, does i9305 has or not support for 3G 1900 MHz?
Thanks a lot!!

Hey self_slaughter AND Obagleyfreer,
Even if the option WCDMA 1900 appear on the list does not mean that i9305 supports 3G 1900MHz frenquency. To make sure you need to select WCDMA 1900 and again to confirm. Then you need go back to the previous screen. If you see a [*] after WCDMA 1900 the device has support. To return it as was before, just select AUTOMATIC on the "first" screen.
Hey highaltitude,
I just got your e-mail!! In your case, 100% sure that 3G AT&T won't work because there's no 3G 850MHz in your State (NC). You could ask AT&T if they have plans to build a 3G 850MHz network in your area. Or you could flash the GT-N7105 modem because it has support to 3G 1900MHz and I think both hardware are pretty much the same.

Ahh ok.. Well in that case I can chose anything on the screenshot I posted earlier except for 1800 and 1900.
I'm pretty sure we use 1800/1900 for lte here in Australia.

Now we know that i9305T has no support to 3G 1900Mhz... I'd like that someone who has the Hong Kong version would try the same thing, but I think the result would be the same... To bad for us from North America...

Where did you get the conclusion that I9305 does not support 1900 3g???

I concluded that based on the self_slaughter and highaltitude said ... In fact self_slaughter has the i9305T which is a Australian version sold by Telstra and he said he could not select WCDMA 1900 option (3G). We know there is another i9305 version which is sold by Optus / Virgin in Australia. Could your i9305 be a Optus / Virgin or even a Hong Kong version? Can you tell us the baseband number, please?
highaltitude,
If btemtd is right, we still have hope to bring 3G for your i9305!!!! ))))

Let me tell You Yes I did Buy this Off Optus. Outright.. No contract
So infact It is the I9305 ALL I9305 is the same,
Now I am using a Telstra SIm card tho.. And I just read your post again you say that you have to go back and see an * next to the 1900? Well Yeh when I go back I dont see an * next to the 1900.
Only for the 850, 900, 2100
But Maybe If I had an Optus Sim card Or a VOdafone Simcard I will be able to select 1900 do you know what I mean, Only way to test this is use my girlfreinds Vodafone simcard in my phone, and then try this again.
I know that Vodafone uses 1 different band to telstra not sure which one tho

Blame Samsung...

No matter which simcard you're using, if WCDMA 1900 had support the [*] would appear on the list, even the i9305 getting no signal... Unfortunately the australian version does not have support to 3G 1900 MHz... And do you know why I wanna buy a i9305? Bacause I hate those Blue and White versions!!!

Black is plain and ugly anyway.
Titanium is pure sex though

I wouldn't hope for Europe, here is no much 1900 Mhz (as far as I know) and like someone said, there is no different variations of international 'i9305' - all the i9305 are the same;
unless of course You have in Hong Kong the variation of i9300 like in US

I have the Hong Kong version just to clarify.
While we are discussing 3g data issues does anyone in the USA have a I9300 working with 3g?

I looked at a few different specifications sites and they show 1900 as being part of the 3G.. and it was australian site...
but they may be wrong. Funny thing is that I chose 850 900 and 2100 and I know that telstra has shutdown the 2100 band so then how come i still have reception when i put it on the 2100 band?
Are you sure about the network simcard difference? Because Different networks sometimes work on different bands
If its I9305 then no matter if you buy it from hong kong or Germany it will be the same because the model number is the same.
In australia we have the I9305T and the I9305 ......The I9305 is the most common one around the world there is also a I9305N i think sweden or something cant remember.
But yeh If the hardware is different then it would not be the same model number. Other wise it would be ridiculous.
I am assuming and I cannot see this being wrong. but i think ALL I9305 is the same hardware... I9305T Maybe different aswell as I9305N
because the reason they have model numbers is to determine what type of phone and specifications it is. So it would not make sense if 1 I9305 is diferent specifications to another I9305, If it is different then it would be a different model number like the I9305t & I9305N.... this is my guess

All though the I9305T is Predominantly in australia as I thought, I also have seen I9305T in brazil I saw it on the Samsung-updates site... firmware was released for I9305T and the region was brazil

agree, but 'I9305T Maybe' - not 'maybe' but 'granted', no one differ the device without the reason;
http://www.morecellphone.com/compar...i9305t-vs-samsung-galaxy-s-iii-gt-i9305/46057
if this is correct, then LTE frequences are diffrent:
"LTE 1800/2600" vs "LTE 800/1800/2600"

I dont beleive this site It says the I9305T is 2 grams heavier and it also says these have FM radio with RDS..
Many many sites are incorrect its very stupid I dont know why these people put up info when they are not 100% sure of it

Maybe they used really heavy paint when they put the Telstra logo on it?
I'm pretty sure the 9305T does have something different to do with frequencies though.
Probably to accommodate Telstras nextg network and whatever black magic they use. No idea on specifics though.
Note: I just remember reading something about frequencies but it may all be horse **** as mentioned above lol.

The only thing that is rumoured to be different is probably 1 less Frequency for LTE As its not needed for telstra. But Like I said I am on I9305 with a Telstra SIM.. And 4G Flys and everything else is fine.
But I would rather have More frequencies to be honest, more future proof... And I do not like having Cariier Logos on my phone which is why I chose to get the Outright contract free phone from an optus dealer.... I was with vodafone which worked fine on this phone but no 4G and I just ported my sim to telstra Pre-paid which i bought for 2 dollars. I put $30 credit and i swear to god i could not use all the credit before the month was over I was like DAMMM thats good

Does htc one dev support T-MOBILE 4G LTE?

I live in chicago but my phone only show the 3G and H icon,Why not 4G?

You might just be in a refarm area without LTE.

It most likely means you are not in a LTE area. 3G is UMTS and H HSPA+. I am sure if it was LTE you would see LTE or 4G on the screen. Run speed test and go to the settings menu and see what connection you are getting. It will tell you if it is one of the top 3. I do not think LTE is in Chicago yet for T-Mo. Also T-Mo changes the 3G/H with a 4G logo to make you think the phone is 100% of the time in 4G mode, it isn't. during sleep/deep sleep the phone goes into 3G (UMTS) to save battery.

Also make sure you have a LTE-capable SIM from T-mo.

H is 4G. It's just the icon the device displays. Some display 4G an some H but they are the same speeds.

Tmobile's LTE is Band IV 1700, no?
The unlocked developer's edition DOES NOT support that signal.
Am I mistaken?
Furthermore, if I'm not mistaken about this too, I believe the dev edition only supports Tmobile's HSPA 21 MB/s. It doesn't even support HSPA+ 42 MB/s.
Please correct me if I'm wrong? What will the refarming do?

It seems to be true that the dev edition will only do 21Mb/s and only where 1900 has been refarmed in regards to HSPA. It DOES support T-Mobile LTE though which is listed as AWS (1700/2100 bands) in the tech specs.

I thought Tmobile LTE is only 1700, which isn't listed from HTC's website of the Dev edition:
Compatible on these frequencies:
HSPA/WCDMA: 850/1900/2100 MHz
GSM/GPRS/EDGE: 850/900/1800/1900 MHz
LTE: 700/850/AWS/1900 MHz (US)
But you also said 2100 which is listed. Is 2100 also LTE? I thought 2100 was only HSPA+? If it is LTE, why isn't it in the LTE category from the website?
All genuine questions. I'm confused.

I won't claim to be an expert on radio frequencies but it I would propose that there's nothing stopping a radio from being capable of picking up two different formats at the same frequency (at separate times). It just depends which format is broadcast at a given frequency in the area.

AWS is 1700/2100. TMO uses 1700 for up or down ( i can remember which) and 2100 for the other. 3G and HSPA wont work unless you are in a refarmed area on the dev edition. As someone said previously, "H" should be LTE since Chicago and suburbs have both LTE and have been refarmed. I have a dev edition and will be switching to TMO next month, and I live in Chicago as well. Im hoping that someone will get AWS frequencies unlocked on the dev edition. In the mean time:
OP try the following-
Flash a tmo stock rom and see what it gives you for signal. It should show LTE instead of H, but no difference in speed.

I will return it and get tmo version

I'm considering this too. Are you doing it for the LTE support?
I would much rather keep my dev edition, but if it's not going to get LTE, that may sway me toward the Tmobile version also. Is that why you're doing it?

Do you mean AWS 1900? So that's 4G LTE?
Then what's the big fuss about "Band IV 1700" LTE? Is that a different sort of LTE? Better? Worse?
Appreciate you clarifying. I'm confused.

It will work. There's various screenshots of it working. Also a HTC rep clarified this not too long ago on Twitter.

onthecouchagain, you gotta actually read man. AWS IS T-Mobile LTE. AWS 1900 doesn't mean anything. Go back and read the specs for the developer edition, it says LTE support bands are 700/850/AWS/1900. See how the third item there is AWS. AWS is the band (or more specifically set of bands) that run T-Mobile LTE. And as numerous people on this thread have already reported, the developer edition works on T-Mobile LTE. The only thing the developer edition doesn't support is UTMS 1700, which means if you don't live in a refarmed 1900 MHZ area OR you don't live in an area where T-Mobile has LTE live, then you'll only get edge speeds and won't pick up HSPA+ on the 1700 mhz band.

[Q] Xperia Z in USA problem

Hi all
I bought the Xperia Z C6603 in UK will it get 3g or 4g or let in NY, USA?
i been reading in the blogs that it wont support you will only get GPRS or EDGE based on this t-mobile thread http://support.t-mobile.com/thread/40671?start=0&tstart=0
but can the Devs do something to make it work on 3g/4g with current hardware in the phone? or should I return and buy the phone when it comes in the USA?
all help is appreciated

I'm not sure about 3g, but I've heard that the 4g bands that the phone uses are different then being used in the States. So that won't work.

As I posted here
http://forum.xda-developers.com/showthread.php?t=2231009&page=2
The reason is, according to T mobile
Depending on where a tower is at in the 4G life cycle, theoretical maximum download speeds range from 21 Mbps – 42 Mbps.
T-Mobile's HSPA+ network operates on the same band as our 3G network, Band IV, which uses 1700 MHz and 2100 MHz frequencies to transmit voice and data services. The 1700 MHz frequency sends information to cell sites and the 2100 MHz frequency receives information.
As with our 3G network, both 1700 MHz frequency and 2100 MHz frequency are required for a device to function. If a device only has one of these frequencies, it cannot use T-Mobile’s 3G and 4G networks.
T-Mobile is switching some 1900 MHz frequency from EDGE to HSPA+. This will allow devices that work on 1900 MHz, such as AT&T devices, to use our 4G network.
and yes,the Xperia z uses UMTS HSPA+ Bands 1, 3, 5, 8 which are
1 for 2100, 3 for 1800, 5 for 850 and 8 for 900
the HSDPA in T mobile are in the bands 1700 and 2100, just like the 3G, and the Xperia Z model c6603 uses bands 850/900/1700 only!!! the C6602 model uses the same bands plus /1900/2100 so, if you miss one band in T mobile you will never have the HSDPA speed, no matter the firmware,because is hardware
This info is according to Sony Official Page www.sonymobile.com, so as you can see you are missing one band, the 1700
Resuming, is hardware issue, and I dont think that the developers will be able to get 4G speeds or even HSDPA if the chip required is missing iin the c6603

c6602 is the only choice
Im currently have c6602 on tmobile and I can get h+ speed on it I did order c6603 and only get EDGE. You will have to set APN manually se the phone canlog into the network. Or u will have to get ZL since I heard that Xperia Z wont be distributed through any US carriers.
