No HSPA data only Edge?

I'm not sure if I jumped the gun on my purchase before knowing 100% this phone would work in my region on my network. I have AT&T in the US. I bought an international GT-i9305 Unbranded, unlocked phone. I found out first that the SIM cards are not the same size. I bought a cutter and cut down my larger SIM from my SGS2 and put it in the SGS3.
The SGS3 came with:
Android 4.1.1,
BB I9305ZHALI2,
Kernel 3.0.31-399890,
Build numberJRo03C.I9305ZHBLJ1
I backed up the IMEI, rooted it and installed CWM (though every time I reboot there is no CWM anymore) Ive been using mobile Odin to flash I9305_CWM_Recovery.tar which gets me into CWM just fine and I can flash other modems, Roms etc. I also use Triangle Away to remove flash counter.
My main question is, Everything seems to work fine, but I get NO HSPA data connection? I only get Edge, and its very slow at best. I didnt realize this at first because I was on my wifi network. Is there a fix for this? Or is it because of the version of phone I have that it won't work on AT&T USA network?

Try this. Go to setting > more settings > access point names > press menu key > reset to default, go back into mobile network settings and make sure network mode is set to GSM/WCDMA (auto mode). Reboot and see what happens.
I have a 9300, was on AT&T until recently and had H+ all the time.

Thanks I have done that. I've also searched the SGS3 Apn settings on the net. No matter what Apn, always the same result.

I believe you are in trouble with this one:
HSPA @ AT&T
"We currently use frequencies in the 1900 MHz and 850 MHz ranges...."
while i9305 operates on 850/900/2100 Mhz.
It's because differences in 2G,3G,4G in all your carries you have so many versions of one model of device

So I assume then, this is a hardware problem not something I can change by flashing a different modem?

stricte hardware

So there is noone anywhere in the USA that has one of these that works?
Anyone want to buy it? Its not going to be worth me keeping it...PM me if interested. Thanks for the responses

Yes international gt-i9300 manufacture unlocked, UK.

So does the gt-I9305 not have 1900mhz? I spent close to an hour on the phone with AT&T trying to see if it would work. They could see the phone, looked up the IMEI and activated a different SIM for me as I cut mine down from my sgs2. Always Edge data and nothing more. All the descriptions I've found online show the same frequencies as my sgs2. Are there different 9305's out there?

I feel special that I am the only person in the USA that has bought an i9305.:good:

I am pretty sure the I9305 has these frequencies
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 850/1800/2600
This is what the specs have always shown. for the one in australia but all i9305 should be the same unless they are i9305t or i9305N
I looked up what australia uses and it does show the 1900 scroll down on this link
http://whirlpool.net.au/wiki/mobile_phone_frequencies
shows this:
3G Hi-band 1900-2100Mhz
The 3G Hi-band 1900-2100Mhz is used by Optus, Telstra and VHA.
Tower Rx /Tower Tx
1920 – 1980Mhz (tower Rx), 2110 – 2170Mhz (tower Tx) using multiple paired 5Mhz and 10Mhz channels
** to be completed **
But you are the first person i know in the US who has bought it purely because you wont be able to have the LTE function.

gsmarena says sth diffrent:
HSDPA 850 / 900 / 2100
maybe for Australia is another model but it at least should have diffrent name

But I have seen more sites saying that it does support 1900 more then sites that say dont, I did a quick search on google and the 1st List of search pages when I type I9305 Frequencies I see that Only gsmarena dont display the 1900 All other sites say 1900 Maybe GSM arena is wrong.
Only the I9305T maybe is different but we also have the I9305 and hardware should be the same.
Only difference from country to country is the Modem SOftware

it's pretty reliable source, but I'd say it's 50/50 (50% says it does and 50% it doesn't)
how about samsung:
http://www.samsung.com/ae/support/model/GT-I9305TADXST-techspecs ??
and if it'd have 1900 then shouldn't it work for highaltitude ?

Well I spent alot of today with AT&T both on the phone and in store. Their system will see the SIm card and that there is a phone, but it will say Unknown Phone. They tried to switch me to a 4G/LTE data plan to see if then 3G/HSPA etc would work but it kept getting stopped because it said my IMEI number is not right or unrecognized. No matter what, their system would not take the IMEI number. I finally got a tech on the phone to put in a correct IMEI that AT&T would recognize, however it still said Unknown phone and still therefore would not let him switch the data plan. I am still at a loss because I swear the specs Ive read are pretty much the same as my SGS2 for frequencies (other than /4GLTE etc) So after one week of having a cool new phone that is stuck with Edge data, I am going to have to get rid of it and go back to the SGS2. Sux, as I really like the new phone.

you are not alone.I bought a Gt-i9305 that came from france/orange before doing my homework.i am on t-mobile and a very slow 2g speed maybe i will sell mine also and get an us sg3.

Yup, got mine for sale on ebay right now.

[Q] Use C6616 modem Z and get AT&T LTE?

meant model Z.........So I just read about this model and see it has AWS and 700 Mhz for LTE - does this mean if I get this phone it will work on AT&T LTE in the U.S? Anyone tried this yet?

also.....Negri Electronics has a unlocked Z Tmobile in black that says it has 700Mhz and AWS LTE bands but they say it can only be used outside U.S. (they list it as international) that AT&T would block it? WTF over?

i dont think at&t will block it. if it supports the at&t lte bands it will get lte but there are multiple lte bands for at&t so if it only supports one of them lte will be spotty depending on the area the phone is used in

Yeah, I don't know......I chatted with a rep there and all he would say is that you cannot use this in the U.S. - I asked if this is because tmobile has a contract w/ Sony and he said I'd have to ask Sony about that. It almost seems like that is what they have to say - but i'm wondering if it would work.
this is what the site says about the frequencies for this model:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network WCDMA 850 / 900 / 1700 / 1900 / 2100
4G Network LTE 700 / 850 / 1700 / 1900 / 2100

i think other users in this forum are using one of the xperia z's with at&t

Yeah, but are they getting LTE? Why the hell Sony chose to release the ZL with AT&T LTE frequencies but not the Z (at least not officially) is beyond me......

probably the same reason it took 6 months for tmobile to get it(which is the the one i have)

I already tried flashing 6616 baseband. Unfortunately, it doesn't have 700 band LTE. It is from Bell, even though they state that their 6616 has AWS and 700.
I'm currently using 6506 baseband but I can't get access to at&t LTE network.

I think canada is getting the C6906 officially, which is suppose to work with every carrier. And C6903 and C6906 are the same beside the H 265 playback according to Sony white paper. So I would say yes.

I received my C6903 today and it works on Rogers just fine with 4G but you have to manually set the APN info.

Or ask your network to send a configuration SMS... You just click it and don't have to do anything!

Canada is (most likely) receiving the C6906 model, which has the LTE band that will for for any carrier really. After some research, Rogers, Telus and Bell all require 700 MHz band frequencies in their phones to get LTE. Wikipedia in this sense is not a viable source of information. I'm a bit lazy but here's Bell's website claiming that their phones must have 700 MHz frequencies: http://www.bell.ca/Mobility/Products/4G_LTE_SIM_card
I spoke to a Bell representative and she very explicitly told me that the version of the Z1 they are getting will have the 700 MHz frequency built in, whether or not it is the C6906 model is something the representative could not answer. As such, it is very safe to assume that Canada is indeed getting the C6906 model.
I'm excited. I'll be getting a friend to purchase the phone outright for me and just ship it over to my ass in NYC. Sure would be nice if I didn't have to wait another 9 days! Would be even nicer if I could purchase the phone myself instead of having a friend do it for me.

[Q] Xperia Z1 c6903 03 c6906?

Hi I'm in SF under tmobile the c6903 works very well under Lte too! If I'm not wrong the 06 is better for at&t Lte but if u check in the other thread there is more than one guy using it on at&t without any issue except less Lte signal.

So C6903 is the way to go if I want to be under T-Mobile, thanks!

c6903 will give you LTE speeds on T-mobile since it supports band 4 (1700mhz) for T-mobile's LTE ,if you go for c6906 you will get band 17 (700mhz) which is used by AT&T for their LTE, along with band 4 (1700mhz) so c6906 seems a better choice if you decide to swap t-mobile and at&t sim cards,also some users have been lucky to get get LTE by using at&t sim card on their c6903 model cause apparently at&t is starting to expand or at rare times uses 1700mhz spectrum for their LTE but i wouldn't bet much on it,700mhz is their prime spectrum for LTE.Hope this helps

Okay thanks so c6906 is the way to go. Anyone have any idea where the best place to buy it is?

yes, i got my phone about 3 days after i placed the order. As for AT&T, i have used my work ATT in it and get 3G but haven't tested LTE. i do get LTE on Tmobile of course where it's available
not sure about ATT LTE though, it seems to be hit or miss for some.

The firmware Works but you cant use 6906 LTE 700 band, because is hardware related.
the difference in z1 models are the LTE modem and the 6903 don't have the same as the 6906.

Do they use the same frequencies in Canada as in the US? In the US, they use 700/1700/2100, and I think 1700/2100 (band 4) is their primary (most widely deployed). If that's true for Canada as well, all four phones should work on LTE. Obviously, I have not tested this so I cannot be sure.

Flashing a 6906 to a 6916 for wifi calling feature
Hey Guys!
I bought a Sony Z1 last year (6906) Canada boot loader locked to use on T-mobiles LTE network and everything worked great, only issue was I lost my Wi-Fi calling feature on the new model as it was not directly from T-Mobile and really liked the feature.
I see that T-Mobile released an almost identical version (6916), only I think has more memory and less bands available.
I tried to pull the wifi .apk file off my original android phone to see if I could make it work, and would not install assuming brand specific of permissions related.
so, wanted to pick the forums brain and see if any one out there has done this, take the firmware for a T-mobile branded 6916 model ( I believe current version is 14.2.C.0.159, until new kit kat release comes out if and when of course ) and put it on the 6906 model so the wifi calling feature can work.
Bands look to be there, so hoping this could work unless someone had a reliable work around for the Wi-Fi calling ?
Please excuse my noobness, new to Z1 forum so any and all help greatly appreciated
Thanks for any help in advance!

I thought bands and signal reception were hardware related not software related.
