Galaxy Note II and Dual Sim

Hello,
Few weeks ago I saw on some website news and photos of a dual sim Galaxy Note 2. The market of the Dual sim is much more dynamic in Indian and china that's why the news said that this dual sim should be for china market and especially for China Unicom.
So would somebody have more consistent news about this dual sim : would it appear ? When ? Where ?
Best regards

Chinese market only

Hello, I already now but I did not see any confirmation if this news is fake or not.
Would it be SIM Unlocked in China, possibility to choose other language etc..

Hmm that would be interesting, especially if its the "international" one. I dont know what kind of cell service they use in china. Will it only work then in China or worldwide with standard GSM and 3G74G and so on?

I already a HTC Desire V bought in China (dual SIM) and it works perfectly in Europe in GSM and data. So from my point of view no difficulties in terms of compatibility.

And how can you determine if it's a real Samsung and no copy mb

Not sure to understand the meaning of your question :
First : the rumoiur and photos of the dual sim never been confirmed by Samsung
Second : if it is real and this dual SIM note 2 is released, don't worry I perfectly know where to buy an original one in China !

main thing you would look at online, is the price. if it's around 200USD it's a replica

I'm from Indonesia and I want a dual SIM NOTE 2 !
But hopefully it's going to be CDMA and GSM network dual sim. Similar to HTC desire VC. But it would be good if the phone is capable to register to 3G of each network (EVDO and HSPA).
Sadly, there's not much news of it now. Maybe they scrapped the idea because it's just too power hungry.

Dual sim Galaxy Note 2 have two different types of version. One from China Unicom, it support for WCDMA/GSM. The other one from China Telecom, it support for CDMA/GSM.It's release date in mid-October.

So, does it mean that the wcdma/china Unicom is not compatible with European network,and the CDMA/china telecom is ok,for,European network ?
Other question : do you have a Link to these informations ?

Rumor have the following models in China
N7102 for China Unicom, WCDMA + GSM, Dual SIM
N7108 for China Mobile, TD-SCDMA/GSM, Single SIM
N719 for China Telecom, CDMA2000 + GSM, Dual SIM

So the only one that should be compatible with Europe 3G should be the N7102 ?

Sadly, it doesn't look like there's one that supports both EVDO and HSPA at the same time.

Are this rumors confirmed yet? And what memory will they have. I am looking for the 32gb version

Dual Sim Note 4?

I wonder if there is going to be a dual sim one?
More over... When the hell is any manufacturer going to produce a phone... with Dual Sim... with 4G!
There is a gsm module...a 3g module...and LTE is another again.
The legacy dual sim ones are 3g on one....and gsm for 2nd sim
Why can't there be one..that uses 4G on one sim...and 3G on the other... or the best answer ever would be.... Dual 4G sims...
I have 2 plans... EE and Three...and both are 4G...and currently using 2 Note 3's.
It's ridiculous!

Sony Z5 Dual - Dual Active SIM or Dual Standby and 3G/4G/LTE active on both?

Hi Folks,
I am looking for a Z5 Dual user who has 2 SIM cards inserted that both have active data connections available with their carriers e.g. AT&T and T-Mobile in the USA or Telstra & Optus in Australia etc, etc.
I am trying to work out if the phone will support dual active 3G or 4G or LTE? The reason why is the 2G network where I am will shut down soon so the frequencies on the 2G network will stop working.
The model I am considering for purchase is E6683 (http://developer.sonymobile.com/downloads/whitepapers/xperia-z5-dual-e6633-and-e6683-white-paper/)
– E6683 UMTS HSPA+ 850 (Band V), 900 (Band VIII), 1900 (Band II),
AWS-1(Band IV), 2100 (Band I) MHz
: GSM GPRS/EDGE 850, 900, 1800, 1900 MHz
: LTE (Bands 1, 2, 3, 4, 5, 7, 8, 12, 17, 20, 38, 39, 40, 41)
I keep hearing that there is no phone that is capable of dual LTE as the battery drain will be huge but with 3G maybe possibility?
Thanks

I'm using a Z5 Dual (E6683) which I bought from Hong Kong. It is a Dual Standby but not Dual LTE. You can select either SIM 1 or SIM 2 to have LTE.
One SIM will be on LTE and the other on 2G.

You can only use data connection on one sim card, the other one is gsm. If it is dual lte or 3g, how would the phone or the apps know which card's data to use? It will be too complicated.

Thanks for your replies, it seems the MotoG is able to maintain 2 data connections, this was reported by another user in XDA forums:

You would think that the Z5 could do the same ?

Hi Guys, just an important question: the device has two slot for the SIM cards and one slot for the SD (3 slots) or just two slot for a sim and and SD or 2 sim ? Thank you
@tasmaniandevil could u help me?

I have 2 SIMs with Bell Mobility here in Canada. Bell doesn't have a 2G network. Would this phone (or any other) be capable of having LTE on SIM 1 for voice and data and 3G on the second one for voice only?

2 SIM slots + SD slot. I only use the 2nd SIM while travelling, so I can't say how they would work atm. But typically on other dual SIM phones, any SIM used for voice-only in slot 2 is okay. At least I haven't run into an issue, but YMMV.

You can choose which sim card you want to be used for data and the other is only 2G. If your BELL card doesn't have 2G network, you have to set it up for data and set the other sim card to 2g only. In that case, you won't be able to use the data on your 2nd sim card.

It only allows 2G (GSM) for the voice SIM? God thing I don't need the dual SIM abilities in Japan. The cell companies don't have GSM aymore,only W CDMA (3G/HSPDA).

Sane model as the one I ordered. Thanks for the screen shots (glad I took French in high school lol)
Somewhat disappointing, but like I said don't really have a use for dual sim, especially while in Japan. Mostly bought it because the regular Z5 was out of stock.
Thanks again.

they are side by side under the flap: the dual has a tray which is kind of annoying to get out and the SD is a push in/out affair

I only know some Chinese phone vendors producing dual-sim-dual-LTE phones, which is achieved via putting an extra baseband chip or something in the phone.

I have 2 SIMs from Bell, with 2 different phone numbers. I don't need data on both because they both share the data but I do need 3G voice on both to be live. One will be LTE data+voice and the second 3G but no data. Anything like that exist?

No, as stated before, you can't have both SIMs connected on 3G. One can be connected to LTE/3G for data and voice but the other is only GSM.

No you can't. One of the sim HAS to be set to GSM. If you set it to 3g of 4g, it automatically set the other back to GSM.

does this phone actually work with WIND Mobile (E6883)
i was looking at the white paper in hk for the device at the Sony store and it doesnt' say support for AWS1700
however, GSM Arena says otherwise

maybe a stupid question, but why do you need data on 2 sim cards? Are you paying for data on 2 sim cards? Because you can switch easily between one sim or the other according to which plan you wanna use.

S8 Dual Sim - Is it 4G/3G or 4G/2G - Dual Standby

Trying to read through as much as I can, but can't find a definitive answer to see if the dual sim options will facilitate a 3G network for the second sim, as in Australia the 2G network already scheduled to be turned off (Telstra Dec 2016 - Optus April 2017 - Vodafone Sep 2017).
From what a can see on the specs pages, it seems the second sim is only 2G/GSM capable, but would appreciate if anyone can confirm or debunk my 'theory'.
I also assume dual won't be available in Oz, so assuming HK best option again (like always) to obtain dual version? Thanks for the advice, cheers!

http://www.phonemore.com/phone/samsung-galaxy-s8-duos-sm-g9500/3233
According to this SIM No. 2 only supports 2G.

it might be wrong. after nougat update S7 edge itself got the option for 3g in secondary sim while using 4g as first sim

Thanks, I appreciate the comments.
The only other mention apart from Columbo_70's link above I can find (at a couple of sites) is similar to this
http://www.gsmarena.com/samsung_galaxy_s8-8161.php - showing the "(dual-SIM model only)" statement next to the 2G networks. Could mean the 2G networks only available on the second sim slot(as well as 3G?) or second sim is only 2G - depends on how you interpret.
Definitive answer may have to wait until phone is in user hands, and user verification can take place, as I tend to feel (hope) same as Quicksilver, that Nougat will give it the 3G functionality.

Currently on S7 edge i have:
Sim 1: lte/3g/2g
Sim 2: 3g/2g
I'd expect s8 to be the same.

I bought a S7 Edge dual sim in Dubai.
I have a subscription to Orange in France where I get 4G+ and a second subcription in France with Free
where I only get 2G.
I installed lately the latest Superman rom 2.4 with Nougat (great rom by the way) and hoped when going to Japan I could finally
get 4G/3G.
I bought a sim card working with Docomo in Japan (internet only, no voice) and hoped for the best as 2G does not
work in Japan.
Unfortunately I am stuck with 4G/2G. Once when tweaking the settings I would see 4G and 2G/3G but it did not work and went back to 4G and 2G to my great disapointment.
I have seen a post from a guy in Singapore saying also he did get 4G and 3G using a beta of Nougat.
May be it depends on the networks, I have no clue.
I hope the S8 will get 4G / 3G as many people are looking for this feature.

kluifje in another thread just posted that the 128GB dual sim version in India would be LTE/LTE .... Let's hope for it

Thanks Everyone, but I've bit the bullet and ordered the Huawei Mate 9 Pro, as it is confirmed as 4G/3G for dual sim. Pity, would have liked to try a Samsung, maybe the S9 or S10 down the track...

Got my S8+ Dual sim today (G955FD). It supports 4G LTE on one sim and 3G on the other. So it is 4G + 3G.

Samsung says S8/S8+ will support 4G/LTE on both SIMS
Samsung clearly stated in their announcement on April 26, and in the specs on their website, that both SIM-1 and SIM-2 support 4G/LTE (FDD and TDD). However, when one SIM is on 4G, the other will be on 3G/2G. This is how my LG G4 works, and it's quite satisfactory, switching back and forth between China and the US. The only downside on the LG is that it does not support T-Mobile's LTE band, so it's on HSPA+ in the US, which isn't horrible, but LTE would naturally be better.. Looks like the S8/S8+ might have the same issue, as I don't see the 1700 band listed.
The following is directly from Samsung's website, for the dual SIM S8 and S8+
Bands++:
4G FDD-LTE: B1(2100),B2(1900),B3(1800),B4(AWS),B5(850),B7(2600),B8(900),B12(700),B13(700),B17(700),B18(800),B19(800),B20(800),B25(1900),B26(800),B28(700)
4G TDD-LTE: B38(2600),B39(1900),B40(2300),B41(2500)
3G WCDMA: B1(2100),B2(1900),B5(850),B8(900)
3G TD-SCDMA: B34(2010),B39(1880)
3G CDMA: BC0(800)
2G GSM: GSM850,GSM900,DCS1800,PCS1900
2G CDMA: CDMA800
++Support 4G Network in HK and China: FDD-LTE and TDD-LTE; 3G Network in HK: WCDMA; 3G Network in China: TD-SCDMA and WCDMA and CDMA. Subject to local network, data and messaging services. If one of the SIM Card is using 4G or 3G Band, the another SIM Card supports 3G or 2G band only, vice versa. Users can choose 4G or 3G network with either SIM 1 or SIM 2 without changing the SIM card

I'm going to HK to hopefully pick mine up at the end of May. Will update with actual experience, if I'm lucky enough to get one.

I had a Galaxy S7 Edge Dual SIM which supported 4G/3G/2G - SIM #1 and 2G Only -SIM #2 when I purchased the phone but recently with the Android N update it enabled 3G/2G support on SIM #2. On a recent trip to Korea and Japan I confirmed that SIM #2 did indeed support 3G as I was finally able to get dual SIM support in those countries (both Korea and Japan do not have 2G). This was not possible prior to the Android N update. I recently purchased a Galaxy S8 Dual (SM-G950FD) and the SIM Card Management menu shows 3G/2G on the SIM #2 so I believe this will work exactly like the Galaxy S7 Edge Dual SIM with Android N.

All current flagship phones supports 4G/3G, it's the current trend, and to accommodate the discontinue of the 2G network in some countries.

Does anyone know, if the specific S8 for China is dual sim active or not? @Chinauser

@Akram - The S8 is dual standby, as said in previous post, but have no additional info. Based on my research on both the S8 and LG G6, decided to order the dual SIM LG G6 (H870DS). I've read that the LG supports 4G/4G, but only one at a time, similarly to my LG G4, but I should know for sure within a couple of weeks.

currently no phone supports dual 4G/4G, only 4G/3G or 3G/4G.

Yes.. meant that both SIM1 and SIM2 support 4G, but not simultaneously. Must switch back and forth.

So SIM 1 is LTE and SIM 2 can be 3G? Which country are you in?

Either SIM 1 is 4G and SIM 2 is 3G or SIM 1 is 3G and SIM 2 is 4G
Only one sim can use 4G at the time. Both SIMs can use 3G/2G, but you have to select which of the two SIM can use 4G in settings.

Idk if it's a HW/SW limitation but 1st SIM 4G or 3G and 2nd SIM only 2G. To get 3G in 2nd SIM you need a Dual SIM Dual Active.

Ups, i thought was a dual standby function. OPT is limited a one sim 4G/3G and the other one in 2G

That is why I'm wondering if it's a hardware or software issue. I think snapdragon 810 should be able to support 3G on second sim...

Both sims support 3g/4g but only one fast network at any time the other sim must be 2g
It's a hardware thing.

If you want 3G on second sim, you must use an OP3/OP3T, OP2 is not hardware capable
