Hi guys,
I'm looking to buy a Galaxy SIII from the States to use here in Australia, and am having a hard time understanding the intricacies of the cellular bands. I get that CDMA stuff is a no go (Verizon, Sprint) and that it seems only TMobile and AT&T are possibilities. Here is a chart with the variants and their banding listed. http://en.wikipedia.org/wiki/Samsung_Galaxy_S_III
The variants support all 2g frequencies, but I don't understand how the 3g part works. The t-mobile one in the 3g band is
850, AWS (Band IV), 1,900, 2,100 MHz UMTS / HSPA+ / DC-HSPA+

, which doesn't include the 900 that some networks use here. Will the phone use only 2G if this is the case? Will that make any difference to me? Will the AT&T one work as well?
Can someone please give me some clarification? :victory:
Below is the info for Aus carriers...
2G
2G, other wise known as GSM, is standard on almost all phones (except CDMA phones in the USA). Most new phones come with quad band GSM support. A quad band GSM phone supports 850, 900, 1800, and 1900MHz.
2G is old technology and provides a fall back position when 3G coverage is unavailable.
Australian 2G bands:
900Mhz (Telstra, Optus & Vodafone)
1800Mhz (Telstra, Optus & Vodafone)
3G
There are several 3G networks operating in Australia. 3G frequencies are usually specified as UMTS/HSDPA or WCDMA frequencies on the mobile phone specifications.
Australian 3G bands:
850MHz (Telstra, Vodafone) – Exclusive 3G band
900MHz (Optus, Vodafone) – available in most metro areas on Optus, with both Optus and Vodafone re-farming the 2G 900 spectrum in regional and rural areas
2100MHz (Telstra, Optus, Vodafone) – Exclusive 3G band
hi i read here in a post that mytouch 4 slide is a 3g in 1900 1700 2100, but according to gsmarena it comes only with 3g 1700 2100, as some tmobile units, my questions are:
does anybody knows the real configuration (only 1700 and 2100, or not)?
is there any radio that comes with 3g 1900mhz, even if its not from mytouch 4g slide, maybe other cause i think that the hardware will work in 1900 as 3g instead of only edge like in 850mhz?
is there any secret code to activate 3g band options?
thank you very much indeed
I would trust the gsm arena spec sheet, but haven't confirmed the bands myself. And not you cannot just add bands, they are interdependent of the radio in that sense, you can not add or remove them

To make it easier instead of using the Freqs (Because they overlap with other bands) here are the Bands that the mT4GS uses: Band 1 and Band 4.
Your confusion comes from T-Mobile refarming the 1900 MHz for 3G. This is the one at&t also uses. It is Band 2.
The mT4GS will not work on Band 2 in 3G only 2G. The hardware was made for Bands 1 and 4.
Use this chart it should clear up the confusion:

hey guys,
i can't really find any information if the Mi4C will work out of the box in europe. i'm in austria on a drei (three) network.
i've read stuff about LTE/4G not being supported in europe but thats dismissable for me. but will normal phonecalls and connectivity up to hsdpa+ work in europe?
thanks in advance
According to gsmarena
NETWORK
Technology GSM / HSPA / LTE
2G bands GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 850 / 900 / 1900 / 2100
TD-SCDMA
4G bands LTE band 1(2100), 3(1800), 7(2600), 38(2600), 39(1900), 40(2300), 41(2500)
Speed HSPA, LTE Cat4 150/50 Mbps
GPRS Yes
EDGE Yes

So check your bands with this
Three (3) only works with bands 2600 and 1900 so they'll both work in the Mi4C. The only band that won't work is the 20 (800 mHz)
I posted some guides on how to unlock LTE bands in here: http://forum.xda-developers.com/mi-4c/general/unlocking-lte-bands-t3215763
Hopefully those instructions work for someone to unlock B20. Let me know if it works!
Hi,
my name is Andrea and first of all thanks to give me your attention.
I'm in europe, italy, and was watching Z3 model d6683, it's for chinese market i guess, particular version of dual sim model. Now, i've two sim, the operator is "3 italia", and its signal is from 3g to 4g (if the area is covered by 2g signal only, i go in roaming signal, and can't surf etc). Now, i'm looking for a dual sim phone, and both sim have to get at least 3g signal at the same time. I'm not asking to surf with both sim at the same time, and i'm not asking "dual active", not interested if when i call, the other sim goes airplane mode. I'm asking if Sony Xperia Z3 model d6683 has two sim can get both at least in 3g mode during standby and always in general, cause i surf with one sim, i call with the other one, but this last don't want to go roaming all the time. Hope it's clear.
I can get this particular model because an Eshop has it online, but first need to know this problem.
Hope it can, and battery can last in any case.
Or if you know some other phones...
Thanks
None has it?
Help please, if you know this model can do what im looking for, or just another phone..
Thanks
Bro i also have D6683 in which one sim will work as 4G and other as 2G.
Hope i have helped you

So the second one can't get higher than 2g? Are you sure, could be the operator..or is just the phone? And if you put sim 1 to 3g, the second always max 2g?
Thanks a lot, some people told me this phone could be the only one to do what i'm looking for, but i guess it doesn't exist.

D6683 is designed specifically for the Chinese market. It uses bands that are incompatible with rest of the world, therefore, it would be mostly useless anywhere else.
The following is from xperiablog.net:
Sony Xperia Z3 Dual TD (D6683) network support
– Dual SIM version which supports TD-LTE in China
– 4G FDD LTE: Band 1 (2100), Band 3 (1800), Band 7 (2600)
– 4G TD-LTE: Band 28 (2600 CMCC),Band 39 (1900), Band 40 (2300), Band 41 (2600 Unicom)

?
Fdd are here in europe, my operator cover 1800 and 2600 lte. Maybe Tdd too.
But could be enough the fact to support just 3g, but the important would be both sim can get up to that at the same time. I'm just asking this.

The only way to make sure is to test it. When I went to China last month my Z3 Dual worked nicely on Unicom's 2600 band. The first time I've read about D6683, I've got really excited until I've found out that it does not support bands used on North American continent wich makes is useless as a world phone to me. If you plan to use it in Europe only, there is a chance that it will work for you. I was not able to find out what 3G bands D6683 supports because the situation there is quite messy. Chinese 3G network is 80% incompatible for rest of the world, the only network that works with foreign phones is Unicom. It's very similar in Japan as well. Understanding that this phone is targeted for the Chinese market, I am pretty sure that it would be useless in North America (and most likely in Europe as well) on 3G bands. Luckily, with the proliferation of LTE networks while 2G is being slowly phased out, we are going to see more phones supporting simultaneous LTE on both SIMs soon.

Of course stay in Europe lol.
But i do not care the fact could not work here, as the fact I want it to support 3g at least at same time.
I guess user niks answerd the question, but i asked to check a few things via mp. But probaly he's right, the phone could show if, after you set connection on sim 1, could support 3g signal on second one. It's impossibile, i have to admit

Thank you. Maybe we re not understanding each other.
I think it can support 3g and even 4g here. My question is when one sim is on 3g/4g,the other one goes 3g? Not to connect data to surf, just about quality, frequency.. at least..
I'm looking one phone it can do it. Seems does not exist.

I do understand what you mean. It would have to be tested, however, there is a very good chance that it might since D6683 can simultaneously run on LTE bands using both SIMs which no Z3 Dual (D6633) can do. Most of the networks in Canada where I live use 3G for voice (same in Australia) and regular Z3 Dual is useless in such scenario, however, there is a chance it would work fine with D6683 which would become a dual SIM phone to go to except LTE bands.
Hope it can. Maybe will buy one to test it,directly.
Ok, Sony America and Sony China say it can't, as user niks wrote.
A Shop wrote on the sony z3 product crearly it can.
Will write to that Shop and to sony hong kong for the last time.
I don't know where to find my D6683 stock rom HELPPPP...!!!

I got a V19 phone from china with Android 5.0. I believe it is a rooted phone, I've seen some of those features. It came in a box that says Android. I have no idea of the manufacturer.
Problem: I cant get the data connection (tmobile, wifi works fine) to get better than the edge network, 2G. I've learned that T-Mobile requires these bands:
LTE Frequencies:
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2 (in refarmed areas)
Lower 700 MHz band 12 (in development) / in service in selected areas
3G/4G Frequencies (WCDMA):
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2 (in refarmed areas)
2G Frequencies (GSM/GPRS/EDGE):
1900 MHz PCS band 2
Inside the battery area the phone lists :
GSM 850/900/1800/1900mhz
WCDMA 850/2100mhz (HA)
When I got to engineering mode, I can see other bands that are greyed out.
So my question is this. Is it possible to slick this phone and install software, etc, that allows the bands I need? Or are 'Bands" hard coded into the hardware of the phone? Easier to just buy another phone with correct bands? Advice or links?
Thanks,
Gary B.
