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’ve been looking into buying an S8 and the fact that each carrier has its own Galaxy S8 variant made me do some research to make sure I pick the correct phone variant.
I wanted to share this with you guys to hopefully have an aggregated listed to help make someone’s life easier when it comes to deciding: is this frequency supported by this model of S8 or will I purchase the phone and end up on certain bands or frequencies only!
Note: The source of this information is Samsung corporate websites only. No third party website was used. And all credits go to Samsung for properly listing their specs. I just aggregated them in one place to be able to compare them.
Please note the US/North American carrier unlocked model will be released later in May.

Thanks for sharing... and it's neat to compared..
i was looking to buy a International version for tmobile, and most of the comments across multiple forums are B12 support is not there for Tmobile..
but the specs says it supported all of Tmobile bands, should anyone has good experience on this..
the specs mentioned is almost matched with most of the sites i referred, hopefully exynos version support tmobile bands..
Commodore Thanks for the info especially the important reference I've been scouring the internet trying to find the one that fits my needs. Any way is there any frequencies for the US unlocked version? Thanks

US unlocked or carrier free version has model number SM-G950UZKAXAA.
It's listed on bestbuy's site but the network specs don't look reliable, for example the lte bands and the lte frequencies don't match up. I will wait until this phone model gets listed on Samsung's support website and go with those specs. They might drag it out until the end of the month to sell as many carrier S8's as possible. Carrier free is probably not on top of their priority list. But since it's on top of my list, I will wait until the end of May and not limit myself to one carrier specially since this phone is so expensive. (And so cute too ...)

Can you look up SM-G955UZKAC? Thanks

I can't find that model. It seems to be missing a letter or two, and in that case the closest match found is a C Spire S8+
SM-G955UZKAACG
Galaxy S8+ 64GB (C Spire)

It's from a new MVNO using Verizon's network, hasn't launched to subscribers. Probably why you can't find it and why I am having problems getting premium care from samsung too. Lol

Ok thanks for the update . So the new mvno probably hasn't even started listing the phone on their site. Something like Credo Mobile perhaps.

Samsung's website for the SM-G950U: https://www.samsung.com/us/mobile/phones/galaxy-s/galaxy-s8-64gb--unlocked--sm-g950uzkaxaa
The webpage lists the FDD LTE bands in the specs, but it does not list any TDD LTE band at all!
I bought an SM-G950U from best buy a few days ago, but given the issue of reliability of specs that you mention, I want to find out (before the return deadline) if the TDD LTE bands listed in the first post are really supported on the SM-G950U.
So, how can I reliably confirm that the SM-G950U supports the TDD LTE bands B38(2600), B39(1900), B40(2300), and B41(2500)?
Solved, using dial code *#2263#
Danny Noman found the solution: Dial code *#2263# lists all active LTE bands on the phone, and on my SM-G950U1 galaxy S8, it shows TDD LTE bands 38, 39, 40, and 41.
