[Q] 2 simcards 1 number

My network service provider gave me a second data only sim card for my nexus 7 3g tablet. So I have 2 simcards but only one number...
Before I got the 2. data only sim everything was OK with the voice+data sim in my SGS3 Mini, but after I installed the 2. data only card in my tablet sms and video calls are "routed" to my tablet. I want to permanently install the tablet in my car so I need sms, video calls and notifications on my phone. I tried to google and read somewhere that the network would use the sim registered last or most recently as primary simcard, so I tried to turn off my phone for a few minutes, but this doesn't seem to solve my issue. I use cyanogenmod11 on both my tablet and phone, so is there anyway to configure calls, sms and video to my phone instead of the tablet?
I tried to search my service providers knowledge base but didn't find any info regarding my extra data only simcard so I guess this is a new option.

No data sim

I don't know how this happened but I only remember leaving the data on the whole night, while connected to wifi. And in the morning my phone just says emergency calls only, no data sim. It is still able to detect what sim I have on but I cannot receive or make calls/texts. How do I fix this? Thank you

Dual-SIM problem

Hi guys!
Did someone of you noticed some problems with using two sim-cards? When i install the second sim card i am constantly getting problems with loosing cellular network connection. There is something strange going on...I tested the new sim card on the other phone and its working normally (so its not the problem with the sim card). Is there maybe a solution to this problem?
Thanks!
Hi guys! As a last resort i did a factory reset of the phone. Its all working now as it should! Strange. Must have been some software bug.
I have been using dual Sims since Nov 2019. I don't have any problems with it so far.
Dual SIM not reachable
Yes, I have constant problems, and I think it's since April or May update.
I use two sims, and sim A constantly keeps "telling" the caller, that "The user is in another call and can't be reached". Then I get an sms with "missed call".
Outgoing calls take lots of seconds to connect.
I've tried shifting the two sims, problem with the same (!) sim card. You'd think this is a sim A problem.... I got a new sim from the "A" operator. Same problem.
Using just one sim in the phone, everything works well, regardless of which, even sim A works fine.
In any phone, sim A works fine by itself. There's something with the software or some setting in the Xiaomi that messes this up.
Support at operator blames the phone.
Support at Xiaomi blames the sim.

No phone signal

Hi.
I upgraded to 10.3.6, retained twrp and magisk.
Now I cannot connect to phone signal or txt.
I do have data connection.
My phone sees the two sim cards but identifies both as inactive.
I have removed, cleaned and replaced both sim cards.
Neither phone carrier are having problems their end.
Also, no sound.
Edit:
Solution:
Reboot into other slot and repeat upgrade correctly.

Does com.android.phone (Phone Services) has stopped error comes?

Question Using Internet while on phone call..

Has anyone else had a problem using the internet while on a phone call? I just switched from the s22 ultra which had no problem in this department.
Is there anyone else experiencing this problem Or is this normal for the pixel?
Do you try to active VoLTE ?
For that you need VoLTE activated. And it is not supported in every country. In order to enable it you need to root your device. I am still searching for fully tested and functional mod for P7P.
Pixel is weird compared to what I was used to from Oneplus. Having 2 Sims in where the physical Sim is for calls and Sms and the eSim for data. When on a call (on phys. Sim) I don't have a data connection on the eSim anymore. When I check "use data during calls" on the physical Sim, as soon as I'm in a call the data card changes from eSim to physical Sim and Internet is available. As soon as I hang up, data connection is transferred back to eSim.
Unfortunately the check box for " use data during calls" is not available for the eSim, also both are provisioned as VOLTE.... Never had such problem with OnePlus, there data stayed on 2nd Sim when I was on a call on first one....

It should still work with UMTS/HSPA if your network has this "3g" network type available, but relatively slow.
You need to upgrade from dial-up to talk on the phone and to have Internet access at the same time.
Big sarcasm here is anyone didn't notice, haha =)
