Does anyone know if the dual sim version of a3 does 4g+3g at the same time? or only 4g+2g? Apparently the a5 and a7 have been confirmed capable of this but a3 is never mentioned
Thanks
Hello,
I just checked, by default, mine is configured for 4G+2G, but i can choose 4G+3G or 3G+4G

First, for the second SIM, i choosed 3G/2G over 2G by default. Then, when i switch, the second SIM always stays in 3G/2G

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.
VoLte from different service providers are going to be rolled out in India very soon. Is our Phone support VoLte feature?
Or shall we wait for another software update?
Any Custom Rom support VoLte feature at present ?
Pls reply
its supported in OOS 3.2.1
using JIO
I activate it (T-MOBILE Germany) and I can't find the settings in the menu [emoji20]
Any idea where to find?

yes, but may depend on carrier, and it's worked since before 3.2.X for me
USA T-Mobile VoLTE works fine.
I've heard USA AT&T VoLTE isn't working yet though. Outside the USA don't know.
Not only is it supported, but you get this ridiculously stupid VoLTE icon in your status bar when you're connected! Hooray!
Yes its supported. Using JIO

Currently you can buy a LYF phone and you will get a JIO connection with it. But it will be locked to that specific handset.
To get a Sim free from handsetlock you need a employee/retailer demo sim.

Im using idea on Sim 1 and Jio Sim 4G on sim 2
Make sire you put the network type to lte on JIO and gsm on the other one.
If you choose LTE for your other sim, since the handset can only support lte fir 1 sim at a time it puts the JIO sim into gsm. And JIO has only LTE band. No 2g or 3g bands. Hence the network drops.

As far as i know. When you choose the mobile data sim in sim cards menu. The option of network type disappears from the settings of the other one. For example. Please look at the attached screenshots.

Yes thats true.. since u told me to set lte for jio sim and gsm for other sim i was confused. At a time only one data connection will be enabled. so i guess the frequent drop is not related to that. Do u face any issue with network drop? im using jio in slot 1 and after couple of hours the network drops and it goes to no network.

The data drops sometimes but comes back usually within seconds. If it doesnt i put on airplane mode and take it off again. That works. But its too rare. I use idea in slot 1 jio in slot 2

If I select cellular data on the Jio sim, both sims have network. But if I select cellular data on Bsnl sim, jio does not get network. I m using on oxygen OS 3.2.6.
It is hardware or software problem?

thats probably because jio is a 4g only network and oneplus 3 doesn't support both sims running 4g at the same time.

That doesn't matter, you can only set 4g network on the sim that has an active data connection. Suppose you have idea and Airtel and both have 4g, which ever sim is your data sim will be able to have 4g access.

A bug or as intended?
Dual SIM, using one SIM for calls, the second for mobile internet. Different networks. Both networks support VoLTE, it is turned on and works fine while using same SIM for calls and LTE at the same time..
But hhen calling from the first SIM, don't have LTE connection on the second.
I understand the reason is maybe because they are on different networks, but I was still expecting otherwise.
An option "use secondary SIM for mobile data during calls" does not have any effect.
CAn someone recreate?
It's dual stand-by not dual active. In dual stand-by only 1 SIM can be fully active at a time.
That is 1 SIM can have an active call and Data, or one active call or Active Data. You can't have 2 active calls on different SIMs or 1 active call and active data on different SIMs.
Update: Adding link : https://en.wikipedia.org/wiki/Dual_SIM#Standby
Oh. Thanks for this.
Hello guys,
I'm facing a weird bug on my oneplus 9pro. When I insert my SIM on SIM Slot 1, LTE+ doesn't show, but just LTE. But when I change the simslot to SIM Slot 2, LTE+ is displayed and I get better speed. Anyone know why it isn't working on SIM slot 1?
thanks
