MT6589 Dual Active Sim - Android Q&A, Help & Troubleshooting

Hi All,
I have purchased Xolo Q1000 (and now rooted) with MT6589 chipset. The box says the device is dual 3G (3G+3G) dual active sim device. I have configured the phone using the below configuration:
1. Sim 1 : Sim for primarily voice calling. No data to be used
2. Sim 2 : Dedicated 3G sim for data
Problem:
The data (3G Sim 2) gets suspended when I receive call on Sim 1. The phone is certainly not Dual Standby due to the fact that if I have downloads running via sim 2, the sim 1 is still reachable; but the data suspends on call.
The demonstration shown by official MediaTek shows the above scenario with only difference that the data connection is persisted. This demo is shown in the following link:
Search Google for :mt6589 sim 1 sim 2 dual active and see the MediaTek result
I understand that I shall be able to pick call with persisting 3G connection, if the voice call is received on the 3G enabled sim. But I want the Sim 2 to be connected and also be able to call using sim 1.
Is there any gap in my understanding?

Most of the specs for the Xolo Q1000 listed the phone as dual sim (GSM+GSM) only, so I think if you are using 3G, the phone do not operate in dual sim standby mode. There are other MTK6589 phones with specs as dual sim (3G+GSM) but not your one.

Not sure where the specs are listed. The box and user manual says that the device is 3G+3G dual active. The marking on Sim slots also reads 3G for both slots.

According to the official site it's DualStandby.
"Go anywhere and be connected. Your OnePlus X is unlocked and capable of using dual standby SIM cards with 4G speeds right out of the box. You have the freedom to use it all over the globe, no questions asked." https://oneplus.net/in/x

Yes, I'm using two simcards. :good:
Also check with your service provider before you buy! I just got OPX and put in my korean and my austrian sim card....and well, surprise! The 3G network here in Korea (and apparently in Japan) does not allow 2 active sim cards in one phone. I'm screwed...
Jep, its working.

I asked and got this answer from UNDERkg on youtube: It's not the matter of allowing or not. Dual SIM phones only support one 3G/4G at a time at which the other SIM gets to only pick 2G signals up. Korean networks do not have compatible 2G networks and therefore the secondary SIM has no signal for itself.
I knew that korea had no 2G network but the OPX description says something like 'dual sim 4G standby' or that's what I understood. so I thought it would be working in korea...
There seems to be a bit of confusion here. I'm very curious to know if the Oneplus X is dual sim ACTIVE?
To be clear there are basically two types of dual SIM phones, active and standby. Standby means you can only use one SIM at a time, so you have to switch back and forth. Active means you can use both SIMs at the same time. In other words you can receive a call on either SIM without switching.
I need to know if the Oneplus X is active or standby.....thanks

Standby SIM | 2G Only?

The preferred SIM is able to pick anything from 2G to 4G, but that causes the standby SIM to have only 2G as a "Preferred Network Type" option.
Is this normal behavior? I made sure the documentation didn't limit the radios on the standby SIM before getting this phone because my one of my carrier does not support 2G, only GSM and LTE.
The SIM works great if I select it as the preferred SIM since it then goes on 3G, but goes back to "Emergency Only" when not preferred.
Is this a hardware limitation on the chipset? I know some other phones are like that (ZenFone 2 for example) but it clearly specifies that limitation on the box. I was expecting both sim cards to be on 3G.
That's dual sim dual stand by on 4g you mean? Forget about it is only marketing on this phone and much other. I have 2 sim from same provider and both 4g or 3g but only one work at same time another has no service same on my LeTv x600. ?

It seems there is much confusion about the DUAL SIM. Maybe I can help... If you insert 2 SIM Cards the following happens, you must choose which card SIM1 or SIM2 will be used for Data Services. Both slots support LTE but only one can be active at the time. Otherwise, both SIM Cards are indeed active (means they support calls and SMS) however the SIM that is not used for Data Service will be "only" shown as GSM (G) while the other will show LTE (4G) in the status bar. Since most providers use GSM for phone calls anyway (regardless of the data connection) your SIM should work both as active and second. Having said all the above, yes, the option for the standby SIM is only 2G - which is really GSM for that matter (or G in the status bar).
GGranello I am not agree with you. In my case provider is not over 2G service only 3G and 4G and have only 2100 band so one of two SIM is with NO SERVICE (of course I can choose The active SIM) but both doesn't work in same time. And for video calls 3G is needed am I wrong? I want to say that on GSM you can't make video calls.

Mr. Claude, my description was meant to explain the way the Phone seem to handle the dual SIM. If Your provider supports ONLY calls over 3G and 4G than you will be out of luck using that SIM as secondary. My (I agree limited) understanding is that GSM providers must support GSM calling in any case but that may be no longer the case. I have used the Phone with 2 SIM cards for quite some time now, one with LTE for Data and the other for Calls and SMS and I had no issues. I have not tried any Video Calls as the prices are quite high here, it is my understanding that you need a 3G (or better) connection for those. And even with Android 6, the P9000 does not seem to support VoLTE calling either.
Yes I am agree with you that this phone does not support VoLTE but neither two 4G or 3G SIM from same Network Provider working together or "DUAL STANDBY"
I have owned a number of dual SIM phones and all of them supported 2G/3G/(4G) on one SIM but only 2G on the other. Before the latest MTK SOCs, it was generally the case that SIM slot 1 would support 2G and 3G (and maybe 4G) and slot 2 only 2G. Now it is possible to swap the SIM functions via the settings menu, but one of the SIMs will still be restricted to 2G.
If your SIMs are both from a provider which doesn't support 2G, like Hutchison Three in the UK, then I'm afraid you will only be able to use one of them at a time. There may be dual SIM phones that support 2G/3G/4G on both SIMs at the same time, but I haven't come across one.
Yep me don't even knowing or heard about one phone that's working with both SIM cards on 4G in same time and actually have 3 phones in my hands all 4G and dual SIM and not work either with 2 SIM on 4G in same network.

Run data on both sims?

Q. Can you run data on both sims
Sim one is straight talk
Sim two is freedompop
Honor 5X has Dual SIM Dual Standby or DSDS. These devices have two receivers and one transmitter. As soon as one SIM becomes active other goes in standby. This is applicable for both Calls and Data.
Dual SIM Dual Active mobiles can have both the SIM active at the same time. In this case, you can use both SIM data in parallel. Since Power consumption is more for Dual Active mobiles, those are not preferred currently.

Dual 4G setting

Hello, I have a question about the dual 4G setting before buying this phone.
I know it's a dual 4G standby, but can you confirm that system auto switch network on secondary sim when receiving or sending MMS ? Is it fast ? Does 2nd sim use 4G in this case ? Does system auto come back to 1st sim after ?
Actually my 2016 dual sim phone can only use 4g for 1 sim, so when I receive mms on sim 2, network is only 2G/edge
so I confirm that dual 4g option allow 4g mms on the two sim cards
