Thanks for the link kchino. So it will work fine with AT&T with 3G speeds.
What about T-Mobile? Can anyone confirm if the device works with a T-Mobile Sim Card ?

No, the 6603 won't work on T-Mobile in the US, calls but no data.

Thanks for the Confirmation guys. Much appreciated. So i guess AT&T is my only option.

Ok Guys from what i understand on the AT&T site. I Can only use my Unlocked smartphone by purchasing a prepaid Plan for 60$/mo and this will only offer a 1GB of Data! 1GB of Data isn't really Enough.
I might Just Get the C6602 Model. does the C6602 model get 4G or 3G on T-mobile Network ?

T-Mobile has refarmed a bunch of their towers to deliver HSPA+ over 1,900MHz.
Doesn't the C6603 support 1,900MHz?

The problem is that the C6603 doesn't support HSDPA on 1700 or 1900. If you get the C6603 you would only get HSDPA if you happen to be in an area where AT&T offers HSDPA on 850. However, the C6603 may be able to use T-Mo LTE in the few areas that it's available.

help! my c6603 only get edge
it freaks me out
i'm using straight talk which can provide LTE for my lumia920
why only edge on c6603?

it works on t-mo, but...

I am in NY area and my C6603 doesn't work with AT&T data; I tried many APN configurations, and sometime the phone was able to connect the web but, strangely, just for some minutes, or data stopped working after reboot. Does anyone has a clue?

[Q] Xperia Z1 c6903 03 c6906?

I am looking to buy an Xperia Z1 and have seen it on Amazon as well as other online sites. The problem is, I don't know what model to get because I live in the U.S. (Los Angeles) and want at least 3G or 4G.

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!

Find out the bands that your network provider uses for 4g/lte and choose accordingly

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.

I put c6906 firmware on my c6903 and it worked. Question is, How will i know if the extra band is working for at&t.. It still gives me h+ in most areas I dont get it. any insight?

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.

@mrled is correct, the LTE support differences between C69xx models is 100% hardware, so flashing other FTFs will not help.

In Canada, a C6903 will have limited LTE on Bell, full LTE on Rogers & Telus, but no LTE on mobilicity/SaskTel/Videotron/Wind. 2G/3G support is identical on all C69xx models.

It will only be a soft-brick, completely recoverable via flash mode (unless you do something stupid like run it low on battery or unplug the cable at the wrong time).

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.

[Q] Change c6603 Into A c6602 By Flashing Firmware Since Same Hardware? Need 1900 MHz

Hi All!
I have an Xperia Z c6603. Getting H+ over ATT networks at 850 MHz.
ATT in my home area only offers H+ at 1900 MHz.
I get no H+ in my home area, since the c6603 does not use the 1900 MHz frequency.
The c6602 works with 850 and 1900 MHZ.
I understand the c6603 and the c6602 have exactly the same hardware.
With that, I believe my phone is hardware capable of both, 850 and 1900 MHz, but not programmed for it.
I have flashed c6602 firmware on my c6603.
The model number on info screens still shows up as c6603.
I still do not get H+ with the c6602 firmware.
QUESTION: Is there any way that I can completely transform my c6603 into a c6602 so I can access 1900 MHz in my home area?
Put differently, since the hardware is exactly the same, I assume it's the programming that activates certain frequencies. Some threads say the modem needs to be "enabled" for these frequencies, which is more than a simple baseband or firmware flash. My c6603 did not work well with c6602 baseband flash. I'd like full compatibility, hence my question about full transformation of a c6603 into a c6602.
Any help would be greatly appreciated!

have u tried to flash modem ?
if u want compatible baseband or thing from another variant to ur u should search for moded of that thing.
so search for modem of c6602 moded for c6603
:good:

Thank you for your reply.
I flashed basebands for c6506, c6602, c6606, and c6616, all with various problems.
I have read in other places that the moden needs to be "enabled" for the frequencies I'm looking for.
But I can't find any information on it.

C5306 - No 3G/LTE on T-Mobile

I live in Sacramento, CA and it's supposedly a refarmed city, meaning it uses 1900Mhz spectrum on T-Mobile for 3G. So I bought a C5306 for my wife, however the 3G isn't working, all we get is EDGE. Naturally I thought I'd at least get LTE, since it's advertised as an LTE phone but I'm not getting that either, even though we have LTE in my area. What's the deal? Has anyone else had this issue? In the phone settings I have it setup to receive LTE/GSM/WCDMA in that order but it doesn't seem to help.
The 5306 claims to have the right bands...
HSDPA 850 / 900 / 1900 / 2100
LTE 850 / 1700 / 1900 / 2100
I'm calling lies on either Sony or T-Mobile...

It's a 5306. Otherwise it wouldn't have LTE listed in the baseband options when you type *#*#4636#*#*
EDIT - I take that back, I guess the 5303 does also have LTE, but different bands. God I hope it's not a 5303, how can you tell? Different ROMs come from different bases and depending on the ROM you install it'll say 5306 or 5303. The stock ROM that came installed on it said 5306, but I installed another custom one and it now says 5303, ugh.

Holy ****, not only do I have the wrong phone, I think I was defrauded in the process. This is a 5303 that was sold as a 5306. The seller just flashed 5306 firmware on top to make it look like a 5306. The picture below shows that it has the 5303 bands (1,3,5,7,8,20) and not the 5306 ones (1,2,4,5).

Does it say C5303 at Model Info? Or on the Box? If yes get your bud to the store

It says whatever firmware you put on it. The C5303 and C5306 firmware are interchangeable. Hence why I think they can sell them as "C5306" phones. This was on ebay, by the way. The only way you can tell is to look at what bands the phone supports, which I did above, you do that by typing *#*#7378423#*#* in the dialer and then going to Configuration in the Service Menu.

i have a c5306 i checked the bands. Anyways i am using it on att and i get h+ but no lte any ideas?
