I want to buy the I9192 and i wanted to know if it supports 2 sims that work only on 3g networks?
Or the second sim slot is only 2g?
Thanks!
Both the sim slots can be used for 3g reception.. but only one sim can be 3g at one tym.. i.e either sim 1 or sim 2 can be 3g at any given time...
by 3g you mean that i can use data only from 1 sim?
I have 2 sims from a networks that uses HSDPA 850 / 2100 - would both of the sims will work at the same time? (I don't need data on both of them, only on 1 sim, but i need reception for calls & sms on both sims)
Will it work?
Thanks!
Yes. Only one sim will be used for the data connection.

yes, both sim cards can recieve calls/sms at any given point,
but for data, only one sim: either sim 1 or sim 2 ( whichever is choosen by you)
your answer!

I made all possible tests, it will only work 3g or hsdpa data speeds on slot 1. if you switch your data service network from SIM1 to SIM2 it will only work 2G, if you go back to SIM1 you will have 3G normally again.
hope this helps. BTW, in the Manual or user guide for this phone this feature is not clearly explained.

I confirm: both sims works on 3g but only one at a same time.
You have to mannually select which sim will use mobile data on settings > my device > sim manager > data service network.
If you choose sim2 for data, sim 1 will automattically switch to 2g network and sim 2 works on 3g.
Make sure your data provider has 3g coverage on your area.
hth
check my post on http://forum.xda-developers.com/showthread.php?t=2490419 for the solution.
Well both work in 3G but only the slot 1 works on HSDPA/HSDPA+ the second slot is locked into GPRS mode and I have experienced this behaviour on 4 rom before knox samsung proctection avoid me to flash my phone as I want.
I am facing the problem of the SIM2(GSM mode only) going out of network when the data is turned-on on SIM1(WDCMA mode only).
I use the following
SIM1 - DATA
SIM2 - Primary calling purpose
Following pattern observed
SIM1 SIM2 Data Turned Observations
--------------------------------------------------------
GSM GSM turned on-either sims Working and both SIMs available on network
WCDMA GSM turned on-SIM2 Working and both SIMs available on network
WCDMA GSM turned on-SIM1 SIM1 Working, SIM2 not available on network (if anyone calls on sim1 it is not reachable)
Signal icon does not rightly depict the same for the third combination.
I have made the above observations by actually calling from other phone with the above combinations.
Thanks

So I've read in a few reviews it's a dual sim standby (both sims are in standby for a phone call) and both of them are capable of 3g/4g at the same time?
anyone know?
reason I ask is in my country the 2g bands are closed so can't use any other dual sim phone (all of them force second sim to be on 2g)
I don't think both of them are capable of 4G for the simple reason 2 SIM from 2 different network providers = 2 IP address, and you need to know it's complex to make usable 2 IP address in the same time (MPTCP).
Then like on the OnePlus 2, you can only use one SIM for data and the other for phone calls/SMS/MMS in the same time.
The only phone that I am aware that is able to do 4g on one sim and 3g on the other is the mi5.
I am also keen to know if we can do the same on the one plus 3. I live in Singapore and 2g will be deactivated soon.

I'm not expecting the phone to use data on both. i'm more concerend about just being on standby for phone/msg on 3g (or 4 if possible). Like using your phone blocking data on the second sim. I don't see why it's so technologically hard. 2g is soon to be gone evrywhere
I have tested Mi5Pro and it have first sim 2G/3G/4G and the second sim 2G/3G simultaneously (dual sim stand-by).
I have read in a review than OP3 also. I will receive mine next monday, i will test ...
thanks a lot. anyone else can confirm ?
I can confirm .. i have received my op3 yesteday and it is 2G/3G/4G on sim1 and 2G/3G on sim2 simultaneously. Sim2 is only for calls and messages.
Like OP2 and other phones, it is possible to swap sims and in this case, sim2 is 2G/3G/4G with data and sim1 only 2G/3G for calls and messages.
I confirm also that op3 is dual sim stand-by and not dual sim active.

So your SIM 1 is on 4G/LTE and SIM 2 can receive calls and text in 3G mode?
Yes but when call is made on SIM2, data on SIM1 is interrupted (dual stand-by)

Is this by design? That seems like a very frustrating limitation. I would be okay with data services flipping over to SIM2 while on the phone there.
I also seem to have a problem of the OP3 kicking down from LTE to HSPA when I make a phone call.
Any ideas?

Yes, it is designed like this, like all dual sim except Asus ZenFone 2, Galaxy S4 Duo and few other models.
LTE networks has not "phone circuits" and call are made in 3G (phone connect in HSPA during call). This is for all LTE phones.
LTE calls are possible with VoLTE protocol witch is IP voice communications and not voice circuit.
For using VoLTE, the phone need compatible with this protocol AND operators needs to activate this functionality.

While you are using data on SIM1, will an incoming call on SIM2 ring on the phone or will the call be treated as though the phone is off-network and be directed to voicemail?

incoming call on SIM2 will ring.
Both the SIMS can receive calls no matter which of them are used for mobile data.

It is dual sim standby and both the sims are in standby for a phone call. Both of them are capable of 4G/3G/2G but NOT at the same time. 4G can be used only in one sim slot at a time. It can be set by going to settings > SIM cards> Preferred SIM for Cellular data. Whichever SIM you choose here will have 4G option. It can be changed from settings>Cellular networks > your SIM card > Preferred network type. (4G or 3G or 2G). The other SIM can have either 3G or 2G but there is no option to choose it. The only way is to click on 'Network operators' option from Cellular networks menu and choose a 2G or 3G service. Hope it helps.
I get 4g on each sim but you have to pick one for data but both are 4g
So if I have 2 sims, one for calls with 6gb 4g and one for data with 15gb 4g, when I finish the 6gb on 1st sim I can switch the data to the other sim via software? Thanks
Your right you can

This is true, but you can also add to the list of "Dual Active" phones all Huawei premium phones:
Mate 7, Mate 8, Honor 6, and probably Honor 7 and 8.
They all have DUAL ACTIVE SIM CARDS, which means that you can have a call on SIM-1 and get a waiting call on SIM-2, then you can answer the call and swap between the two active calls!! I even tried calling SIM-1 from SIM-2 and it was actually ringing!!
Also more importantly, when using data on SIM-1, you can make or receive a call on SIM-2 without interrupting data.
That's pretty amazing, but with a major drawback (at least for me, it is): 3G/4G service is only accessible on SIM-1 slot!! The SIM card in slot-2 will always be 2G and would never ever access 3G/4G networks
This is bad because I travel a lot, and I always need to be able to switch data from SIM-1 to SIM-2 and vice versa. The only option I have is to physically swap SIM cards between slots, which actually ruins the whole concept of having DUAL SIM mobile
My guess is that they are actually using two separate modems, each one is dedicated to one of the two SIM slots, and only one of them supports 3G/4G connectivity.

so, you are saying that both sims are 3G/4G capable, but can be used for data one at a time, and can be switched anytime via settings ?
I have a questión, so if a dual sim phone have 3g/4g capabilities on both sims, is there a way to make like a failover setup such as if sim1 looses data the phone switches to sim2 data automatically and viceversa?
I have problem in my one plus 3 network issues both SIM are not working properly both SIM search for network frequently when I switched data no network can anyone give solution I tried all rebooting, factory reset, searching network manually.
Is there any way to enable individual sim settings
SIM 1 -2G
SIM2 -4G
Now we have only one settings.Any Help to enable in OxygenOS????
Make SIM 1 default for data, change network to 2G.
Make SIM 2 default and change network to 4G.
Done.
(you can also change network of SIM 1 from the testing menu *#*#4636#*#*)
I am from India and have two sim cards on my device.
Sim 1 - Jio which only works on the 4g spectrum and calls are over VoLTE.
Sim 2 - Vodafone which can work on 2g/3g/4g. Calls are not over VoLTE.
I have data packs on both the numbers.
In the settings when I switch my data subscription to Sim 2 i.e. Vodafone, the phone immediately enables 4g on Sim 2 thereby disabling Sim 1 because the Sim 1 only works on 4g.
I would have had no problem if the phone could just let me use my Vodafone Data on 3g but no, it forces the it to use it on 4g and therefore if I want to use data on my Sim 2 I can no longer user Sim 1.
Is there a work-around for this issue?
