( notice that my old nokia n73 never loses network coverage like this suddenly in my home :/)

1: This is a question so this is not the correct place to ask
2: Is your simcard cut into micro sim? If yes ask a new one at your operator, i had the same issues until i orderd a new sim

[Q] Experiences with AA and Dual SIM Phones

Hi all !
Does anyone of you also have issues when connecting a Dual SIM phone to AA and trying to place & receive calls ?
In my case - when i connect my OnePlus X (CM13 Custom ROM), AA and the Phone crashes if i do not set a default SIM for outgoing calls in the Phones SIM settings (Option "ask before each call").
I couldn´t try with Stock ROM because this caused Bluetooth Errors with the Cars Media System (no Contact Sync)
Headunit is a SEAT Media System Plus (Alhambra 7N 2016)

Hello fellow OpX user.
I've not got a secondary SIM so can't answer your question. However we are both using the same phone and head unit so I was wondering what your experience with AA is like?
I'm on stock and although it works well I do seem to get constant disconnects, especially if I'm travelling on a specific section of road I can guarantee it'll disconnect there.
Do you have issues this issue on cm13?
Oh and I fixed the Bluetooth contacts issue with an app called Bluetooth Phonebook. Just the HU can't read text messages

I think it is because of your ROM. I also use a custom CM13 Rom (Mokee, on a nubia z7 mini) and for me it works. The disadvantage however, is that I have to select which sim to use on the phone. So it does not offer me a choice on the headunit but only on the phone itself. If I do not select a sim on the phone, the call simply does not go trough.

Hi !
I'm running Sultans CM13 Rom for almost 3 months now and it's working perfectly well.
I have nearly no disconnects in AA and Bluetooth is also stable (phonebook, messages...)
The Problem i described in my first post was caused by my flip cover - when it's closed while connected to Bluetooth handsfree and i place a call the phone APP crashes - seems to be a common bug caused by proximity Sensor.
-> not ROM related..
At least for me switching to a custom Rom was the best decision....

Cheers @error23 that's interesting that you have no issues on Sultan's ROM. I'm beginning to suspect my issues lie with either GPS signal (but I think that'd be more random) or when switching between certain types of Cell Masts as it's always in particular locations or routes.
Out of interest, which country are you in and do you know which bands your network uses for LTE? I'm in the UK on o2 which only uses band 20 for LTE.
At the moment I'm running the OnePlus marshmallow community build.
Thanks

I'm in austria on the 3 network - using LTE Band 3 (1800MHz) and 7 (2600MHz). I have no disconnects when changing cells, even not when it falls back to 3G or national roaming (which is 2G)
But - as mentioned - OOS didn't run stable with AA for me and i expect its Bluetooth related, but who knows

Guys, how did you solve that dual sim select when calling using Android Auto?

I am afraid there is no real solution. I still have to select the Sim card I want to use on my phone. It looks like Android Auto is not really ready for dual sim use. When using voice dialling however, it once asked me which sim I wanted to use. To this day, I am still waiting for it to happen a second time since it looks like a very useful feature.

I am using a Moto Z Play with 2 SIMs. The issue I have is that I am able to make phone calls from Android Auto ONLY if the SIM being used to make the call is the same SIM which is being used for data at that point in time.
I am unable to make the call if I use SIM 1 as my default Data SIM and SIM 2 as my Default Voice SIM and vice versa - the error I get is "Network not available".
I thing this is a serious issue that needs to be addressed.
Incoming calls seem to work fine though.
Anybody with similar experiences?
Best,
Krish

Yeap, that's me, unfortunately. I am waiting for a possible fix by Google, because it is rather uncomfort having to disable the 2nd SIM each time I enter my vehicle.

I am using Xiaomi Mi5 Global edition running Android 6.0.1 on MIUI version 8.1.2 Stable. Android Auto version running: 2.2.710804-release. Exactly same issue as yours.
My default SIM setup: SIM 1 for data and SIM 2 for calls and text. When using only one SIM for both calls and data, Android Auto works fine. However, with my dual sim setup, I get "Network not available" when I try to make calls. Incoming calls and texts are working fine though...

Hello,
Oneplus2 Oos 3.5.8
After some test I confirm that using same default SIM for both call and data is needed to use outgoing call in AA. If not (or if call setting is 'ask everytime'), I got the Network not found message.
Yesterday I did a real quick test with the app Dual Sim Selector Pro using basic settings. It did work, even if I was very surprised. Later I bought the app and start to configure my phone.
This morning, it was no longer working.
I was going to give up and I read this message about the android setting needed to be similar in data and call.
IT SEEMS TO WORK!!!!
My setup:
SIM 1 is for private matter and I use mostly this one for data
SIM 2 is work related
In Android settings:
Default call: SIM 1 (my dream setup was to use SIM 2 but w/e)
Default SMS: SIM 2 (mayble i'll have problem to use sms app but I dont use it while driving)
Default Data: SIM 1
In Dual Sim Selector pro:
Main screen: activated, SIM 1 as main
Automatic select screen: activated, and in group tab I've go my works groups with SIM2 and private groups with SIM1.
When using Android Auto, the calls are made with the right sim!!!!!

Anyone interested in a dual sim add-on for AA?
Hi everyone!
It is quite a while ago that someone last posted in this thread. So far I was reading in this forum regularly but did not post anything yet
Since I use a dual sim phone (Samsung Galaxy S10) with my private and my business sim card running in parallel I also was facing problems when dialing while driving with Android Auto - in phone screen mode, but I will get a new car with support for projection to in-dash head unit soon . AA does not allow me to select the sim card to dial with for the next call when Android Auto UI is shown.
This was anoying me so much that I started to develop a simple Android app which allows my to select the right sim card easily while driving. It is a kind of unofficial add-on for Android Auto. It is doing the job well now but is only tested on my personal device.
Are there other dual sim phone users in the XDA community that are interested in using / testing my helper / add-on app? If so I would try to publish it in Google Play Store as a public beta. It is free! Please give your brief feedback in this thread.
Regards, Gero

Hi, I'm a 2sim user with a opel mokka car.
Don't know if my AA is up to date enough but if you want, I can du a try. Write me in PM if you want

Hi, thanks for answering. Currently I am stuggling with getting the app approved by Google for publishing on Google Play Store. When it will be publically available for download I will invite you for beta testing

Dual SIM

Hi, I am shortly going to have an mi5. One of the reasons I bought the phone was to have one phone and 2 SIMs thus doing away with the need to have two phones (personal and private) with me. But I am totally new to the whole dual sim thing. Can anyone explain how it works on the mi5?

All in all,
you get to choose if you want to use data from SIM 1 or SIM 2.
When u get att call it says Incomming call on <Call provider 1> or <Call provider 2>.
The same when you wanna call or text someone, either you tap SIM 1 or SIM 2. All of this could be configured in the settings menu.

Cool, thanks.

Thats incorrect, can be 2G/3G/4G, the other sim is 2G/3G.
To ther op's, for all I know, the P7 and 8 is full active, you can use sim one to call sim two and you phone will start to ring, thats the same for sim one on call, whiles data can be used to surf the internet on sim two. This feature has been removed for all released afterwards.

Thanks Bro, if the 2g/3g sim received a call .. the internet stopped working?
Example: Is the truecaller worked to identify a number call me on 2g/3g sim card?

Lets just say that when sim 1 is active (on a call), sim 2 is disabled.

Nothing can be done about it, of all the phone only Huawei P7 and 8, from what I know has this feature, all the newer Huawei has removed the feature, and other manufacture thinks it's not worth having it.

Mate 10 pro dual SIM

Hi there, i just got a BLA-L29 upgrade from a Mate 8. The main reason its that i need a dual SIM phone and the way it was implemented in Mate 8 was brilliant. Both Sims were active on the same time, if you're in a phone call on SIM 1 and you get a call on SIM 2 you get a notification and you can put the first call on hold and take the other one. Same the other way.
Can this simple set be achieved on Mate 10 pro?
The only setting i can find are just call forwardings between SIMs, that's more than lame as its costing money and not reachable some time (for one of my SIMS the provider only offers call forwarding to the voicemail, not a different number).
Thanks

Maybe something to reach out to Huawei about?
I would have thought this was possible since both Sims are supposed to be active, even on LTE, simultaneously. I just tried it however (receiving a call to Sim 2 while talking on Sim 1) and even tough I can manually put the Sim 1 call on hold, the call will disconnect as soon as I answer Sim 2.

Hi, I have the Dual Sim Mate 10 pro, but actually I only use it with 1 sim card.
However, I have a notification always present saying "SIM 1 call forwarding" - is there any way to disable this feature!
Thanks in advance
