Dual sim not working as wanted - OnePlus 6 Questions & Answers

Hello,
I use dual sim, one for job calls and second for private calls and data. I have noticed that I cant receive calls on job sim which does not have data enabled. Calls go directly to voice mail and I dont get any alarm.
I have also noticed that job sim works properly when it is set to 2g. However 2g setting always resets back to 4g after reboot.
Is there any way to force second sim to be only in 2g for calls even after reboot? I have rooted device.
Thank you

Because it is trying to use VoLTE which is using data and you don't have data enabled

[Q] Dual sim mobile data on call switch

So i got letv x600 dual sim phone, sim1 for calls only, sim2 for mobile data only (lte only set from the hidden menu *#*#4636#*#* [btw there are only options for sim2 sadly]), and i wonder if theres any way i can force sim1 to use 3g/4g automatically just when i call so i can get the "HD Voice" option for better call quality, and after a call ofc mobile data back to sim2? cuz switching it manually is a pain in the ass
Sorry for bad english and probably stupid question but it rly bothers me if this is even possible
Ps. i wouldnt mind if the call would take few secs longer cuz of network switching.
anyone?

no reply!!!
dear all please reply, i need help!!!!
what a shame no one has replied until now!!!!
Did you try factory reset or xperia companion repair? What if you reboot in safe mode, does it still happen?
To me it looks like a bug, I'd report it on sonymobile website too.

As i understand these are Dual Standby SIM setup wherein if SIM1 gets call, SIM2 is currently becomes unavailable or is temporary offline until phone call on SIM2 has ended and vice versa.
This explains why data on SIM1 disconnects when making or receiving calls on SIM2. Both SIMs cannot make or receive calls simultaneously.
With your setup, Calls have higher priority than data, so data is disconnected

Mobile data not working during call

Hi
I am having an issue with mobile data being turned off during a call. I have a dual SIM S8+, when I call on sim 1 the data on sim 2 turns off.
I have it set up that sim 1 is calls and texts and sim 2 is mobile data.
Any ideas how to fix this
Thanks
S8 is dual sim dual standby and not dual sim full active, so when one sim is active on a call the other will be deactivacted and cannot receive calls or used for data at the same time. It is not an error and it cannot be fixed.
Thank you for that. If I just use one sim on the phone. Then will I have data active while calling?

If you have data set to sim 1 you will have data during a call on sim 1, but not while on a call on sim 2, and vice versa.
If you only have one sim in the phone, you will always use the same sim for data and calls, so you will not luse data.

Dual SIM automatic data switching

Is this possible with the OP6? I have a private SIM (SIM1) with a 10GB dataplan and a company SIM (SIM2) with a 1GB dataplan. My Sim2 is the default SIM for calling and the SIM1 is the default data SIM.
Whenever I make a call, my internet connection gets disconnected because there can only be one SIM active at a time, but I need a connection during the call so it would be very handy if the phone switches the data connection from SIM 1 to SIM 2 during the call (and back when finished).
I saw this is a feature on the Huawei P20 but did not find a setting on the OP6.
The quick tile button "switch data card" doesn't work during a call....

Having the internet cut out doesn't make sense, I have AT&T and T-Mobile with dual-4G enabled and when I have a call on SIM1, I maintain LTE on SIM2. Also check if your carrier supports VoLTE, as this will use LTE for voice and you won't lose data when calling.

I also have dual-4G enabled but the connection drops as soon as I have a call. VoLTE is not supported at all in the Netherlands on the OP6.

I too see the connection being cut when I have a call on the SIM that is not data by default... I see the data being stopped on the SIM 1 but it does not start on SIM2. In general I have to say that it seems it takes a long time for SIM2 to get data connection established when I test moving data on it. So this might be the root cause...
I have the same problem, any solution to this?

Dual SIM VoLTE Verizon and Fi

Hi all,
Here is my situation and problem. I have 2 Sims:
SIM 1: Google Fi - my personal number, I want to use it for phone calls only even though it has a small data lan
SIM 2: Verizon - work sim, I want all the data to go through here.
My setting is phone call sim 1 and data Sim 2.
When I make a phone call via SIM1, I lost LTE on my SIM2.
I did call Verizon to get the CDMA LESS feature turned on.
If I were to change the setting to phone call and data through the same sim, then VoLTE works just fine. So I think this is an issue with the phone itself/settings.
Thoughts?

You need to go into settings "SIM & network settings".
Select "Dual 4G networks".
I don't have your issue.

I have a similar problem. Voice on SIM1 data on SIM2 different carriers. Receive calls and text OK answering won't work. Roaming in Europe. Worked OK prior to recent update. Same setup works on Samsung S10e

Can't believe there are so few of us having this issue. Why would the LTE turn off when I'm not even using that sim?
Probably many are using just a single SIM.
Have you tried switching the sims in the slots?

I have no help. In January Mint had an issue where their SIM had to be in slot 1. So I flipped SIMs. Truphone won't work either.
