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 saw that you can pre-order the Ultra 3 on Amazon.fr and Amazon.de. This must be the EU model. Releasedate on Amazon.de is 28 december.
EU modelnumber:
White: 90AK0012-M00420
Gray: 90AK0011-M00400
Pink: 90AK0013-M00410
really interested to see if this model will have different LTE bands than the Asian counter part.

yes, this might be great news, or a great disappointment. let's hope for good news!
GSMArena doesn't seem to list the bands: http://www.gsmarena.com/asus_zenfone_3_ultra_zu680kl-8130.php
An online shop (which I don't fully trust, so I won't give a link to eglobal) suggests 4G on
700MHZ 700MHZ
(B20) 800MHZ (B20) 800MHZ
850MHZ 850MHZ
900MHZ 900MHZ
1800MHZ 1800MHZ
2100MHZ 2100MHZ
2300MHZ 2300MHZ
2600MHZ 2600MHZ
which in theory covers some UK carriers (officially 800 and 2600, but some are using 1800)... but as I say, I don't trust them.
the 3G bands listed are these
800MHZ 800MHZ
850MHZ 850MHZ
900MHZ 900MHZ
1900MHZ 1900MHZ
2100MHZ 2100MHZ
which omits 1800, which is odd. I'd have thought that these phones would be multimode and be able to run 4g or 3g on a common set of bands.

I can't find the phone on amazon.de any more. I wonder if they pulled the listing after mistakenly posting it? It's still on .fr, is eur650, which US$680 or GB£555.
That makes it quite a premium. I've seen it as little as £410 elsewhere, but that would be an import.
doesn't appear to be on amazon.es either.
I just noticed that WondaMobile now list this phone, and I trust them a little more to get the tech specs right

Hi,
I'm thinking of getting myselft a moto g 2015 turbo edition xt1557.
I am ready to give up on band 20 (seems to be impossible to unlock it on snapdragon devices) and living with 3g where 4g is only delivered on band 20.
While I was roaming the internet I landed upon an italian page that gives all information about chinese handsets.
Among those informations there is a worrying one:
european 3g bands are 900 Mhz and 2100 Mhz. Same as China, but they can't be used as EU uses UMTS-FDD, while China uses UMTS-TDD.
I think I understood that merlin was for the Indian market. Since I can't find this information anywhere else, could someone tell me which 3g merlin uses?
Thank you very much indeed for your help in advance.
Have a nice one.

Keep in mind that country and service provider play a significant role as well, just because a band is available in the EU doesn't mean that your provider has access to it. There was also a thread discussing unlocking freq bands, but it hasn't been too active lately, so I wouldn't put a lot of faith in that option.......
as for the bands,
xt 1557 uses :
2G : GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
3G : HSDPA 850 / 900 / 2100 -
4G : LTE band 1(2100), 3(1800), 7(2600), 8(900), 28(700), 40(2300) - XT1557

Hope that helps.
Thank you
Hello everyone.
Please, I'm searching online for this for days now and can't find anything useful for our Note 3. My carrier uses 700 MHz for lte here in my country and for urban areas it's a must have because of it's enhanced penetration.
So, my question is if the Snapdragon 660 does support this frequency on the hardware level and it's locked just by software or there's no way to enable this ever? And if it's possible, someone knows how to unlock this band specifically? Flash a custom modem or anything? I'm running miui 9.6.2.0 rooted.
And since I'm already here... I can't change permanently the settings in Phone Info (menu *#*#4636#*#*), the preferred network type always go back to LTE/TD-SCDMA/UMTS and I can't enable permanently Volte Provisioning either. It always go back to off.
Any help would be much appreciated.
Thanks in advance.

These are the bands supported by the phone:
2G bands GSM 850 / 900 / 1800 / 1900 — SIM 1 & SIM 2 CDMA 800
3G bands HSDPA 850 / 900 / 1900 / 2100 CDMA2000 1xEV-DO
4G bands LTE band 1(2100), 3(1800), 5(850), 7(2600), 8(900), 38(2600), 39(1900), 40(2300), 41(2500)
B20 (800Mhz) is not supported and is not possible to unlock it.
B28 (700Mhz) is not supported and is not possible to unlock it.

First: if your carrirer doens't support Volte tecnology
Second: if your carrier support Volte then is also necessary that the firmware of the your phone is compatible specifically with this carrier.
If not these conditions then is normal your behaviour
I have a LG G3 D850 which is outside of US unlocked and works on local carriers however the problem is I only have 2G edge connectivity for mobile data. I have read the thread but in my case there is a difference i.e., I am able to receive 3G/4G connectivity on only one of the local carriers that operates on LTE Band 5.
According to LG G3 D850 specifications it supports:
HSDPA 850 / 1900 / 2100 - D850
LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 17(700), 29(700) - D850AT&T states that it uses Band 1,3 and 7 as roaming bands.
Could the problem be that in my case these two Bands 1 and 3 are locked and thus I cannot get 3G and 4G connectivity for all my carriers. In that case should I still flash a qcn file or should I proceed to unlock these bands first. I can tell you that I definitely see these two bands in the phone's service menu and can select them successfully (which kind of indicates the bands are unlocked but I am not sure).
I am really confused on how to proceed. Could someone kindly help me out here.
Best Regards
