Can't receive calls while using data in s4 mini duos? Solved - Galaxy S 4 Mini Q&A, Help & Troubleshooting

I had this problem: In my galaxy s4 mini duos (gt 9192) I use both SIM cards for voice and the SIM 2 for data connection. So SIM 1 is in GSM only mode and SIM 2 is in GSM/WCDMA auto select mode. I leave the mobile data always on and I got lot of dropped calls to the SIM 1. Every time I pick up the phone there were lot of messages which were Missed Call Alerts to the SIM 1. There was no problem in receiving calls to SIM 2.
With some testing I noted that the phone does not receive calls through SIM1 whenever the data connection indicates H+ sign ( Data connection is though the SIM2). Yet I could receive calls when that data indicator indicated as 3g. Finally found a solution to this.
Solution: Go to Settings -> My Device -> SIM card manager and put the tick on Receive Incoming Calls, which is the first entry under General tab.
It gives a warning message saying the data speeds will be reduced by enabling this option. Still when I enabled that option, I did not see a significant reduction in speeds. I get all the calls from SIM1, yet the data connection drops whilst the phone is on a call in SIM1.
Think this works vice versa, that is Data is on SIM slot 1 and voice only SIM is on SIM slot 2.
May be this is a well known thing. I posted as this might help someone.

Network drops

In 4.4.3 kitkat the network is fine... But when I upgraded to lollipop (5.0.2,5.1) Im facing some weird problems that some network goesoff and again automatically it's back aftersometime...I have replaced with new sim card though the problem still occurs but the simcard is working fine in other phones.... And mainly this problem only comes with "idea network" remaining all networks r working fine in my phone
I had the same problem. When I used:
Sim 1 -> GSM only for phone calls
Sim 2-> WCDMA for calls and internet
The problem occurs while placing a phone call. I hear a beep during the call and both networks are restarted leading to a drop in the call and 5 seconds until the networks are back.
I swapped the roms in terms of connectivity and switched my data plan to the other sim card, so:
SIM 1: WCDMA for calls and internet
SIM 2: GSM only for calls.
Now it is working perfectly fine.
To me, it seems to be a bug in the firmware that it triggered by some networks while on the dual mode.
Hope this helps you,
Good luck

Using Dual SIM On XT1676

Ok, and advice appreciated.
Have just put a SIM in the second slot in my G5. Am running a Vaya SIM (voice, data, sms) in the actual primary slot and a Telstra (voice only) in the second slot.
If i select the Vaya as primary SIM for all three (voice, data sms) in settings it works fine.
But using an app (Dual SIM Selector) to select what SIM on a call by call basis, it wont send or receive calls on the Telstra SIM and tells me mobile network unavailable for voice calls.
If i go to settings, and set the Telstra SIM as primary for voice, data and sms (needs to be set for all 3 regardless no data plan on that SIM) then i can make and receive calls from the Telstra SIM no probs.
So both SIMS are active, and both SIM slots work with a 3 or 4G card. Have swapped SIM cards in the slots and all as above. SIM cards are good and slots both work.
What i was hoping for with a dual SIM phone was for the Vaya SIM to be active for making / receiving calls, SMS and data as normal, but for the Telstra SIM to be "listening" , be able to receive calls , and make calls when selected on a call by call basis.
Now,being in Australia and having had the 2G network shut down late last year (3 and 4G only now) i am wondering if that has something to do with this??
Anyhow, wondering if there is anyone out there who knowing more about this dual sim thing than i has any ideas??
Hmmm........did some checking and think my problem with the dual sim thing is due to the 2G network on telstra and optus being shut down.
Seems under the software on the G5, whichever SIM card that is NOT set to handle mobile data, tries to default to 2G as preferred network (under Settings / More / Mobile networks) and the "Preferred network type" button is greyed out and inactive.
Of course no 2G network when you try and make a call it tells you no network available. Sadness.
So, unless Motorola come up with a fix, or deal with this in their next update for Australian phones, i think i'm stuck on switching between SIMS, and NOT having the second SIM able to listen out and receive calls, which even if both SIMs share a radio seems a no-brainer capability to have to me. Have sent a begging email to Motorola asking if they have a fix / workaround and would they consider thinking about this for next update? Pretty much all i can do, although if there are other Australian users with similar issue wouldn't hurt for them to contact Motorola support as well??
Anyone know how to set up a "shortcut" direct to the SIM config page in settings?? App or widget for that??
Am hearing on the G5 Whirlpool thread that there is an update / fix in the works and maybe on the way from Motorola to deal with the dual sim issue (defaulting to 2G) on the Australian G5.
Got the below from Motorola support today. So, fix is on the way.
Good day!

Phone looses 4G Data & Call function on turning off data. APN Settings auto deleting.

Phone looses 4G Data & Call function on turning off data. APN Settings auto deleting.
Hey, I bought a Nokia 6 2018 a couple days ago. Its great but has this one problem. I am using the Indian Model TA-1089.
I have 2 SIM Cards, one is by carrier JIO and another by TATA DOCOMO. I use the JIO SIM as prefered SIM for Data, Calling and SMS. When I put the JIO SIM in SIM Slot 1 and start the phone, it works uptil I turn off Data. Once I turn off Data and let the phone sit for a few mins, the next time I turn on Data the phone doesn't latch onto 4G connection and I don't get internet connection. Also, I cannot place any calls via the same SIM. When I try to place a call, I get a popup saying "Mobile network not available". Although I can receive calls for some reason.
While trying to find the cause of the issue I found out that when the problem occurs, the APN settings are automatically deleted from settings. If I try to manually add APN Profile with the correct values and try to save it, the profile doesn't get saved at all. Also, resetting the APN does nothing.
I tried resetting the network but the problem persists. Factory reset didn't fix it either. Tried another 4G SIM and the same problem occured with it.
Restarting the phone fixes the issue temporarily. So does deactivating and activating it. But its such a hassle.
Surprisingly when I put the JIO SIM in SIM Slot 2, it worked flawlessly. But it still doesn't mean the SIM slot 1 issue is fixed.
Has anyone else had this issue? Please help.

3G / 4G Mobile data doesnt work when active call is in progress

Hi guys,
Did anyone here notice that when you have an active call which is on loudspeaker, you cant browse the web with your mobile data! I am hoping this is a setting which i can disable / enable to allow me to browse the web with my mobile data when currently on a phone call with someone.
Quite annoying and i am not sure if its a bug or a settings.
Would appreciate it if someone can shed some light
Thanks!

The same to me. But i know it isn't because of the phone or miui. If your carrier doesn't support VoLTE, the phone will temporary be disconnected 4G during calls.

Hey guys,
Doing tests it seems to be a bug.. I have 2 Sims in my phone, if I get a call on SIM 2 which I use for receiving calls (this has no mobile data) and I try to browse the web it does not work, my SIM 1 is the SIM I use for browsing the web with mobile data because I got unlimited data on that SIM. It seems that when on a call with SIM 2 and I try browse it is using SIM 2 for the browsing (but this fails because I got no data to use on SIM 2). If I get a call on my SIM 1, I can browse the web successfully while on the call! So it seems to be a setting or a bug or something to that effect? Nothing to do with volte etc.
Any ideas?
I rang my operators and they all allow for browsing and phone calls.. doing standard tests the above is what I got. So it seems to be a dual SIM issue or something?

Looks like the SIM you're making the calls from doesn't support VoLTE or doesn't have it enabled. Without it the phone will drop to 3G when making calls and you won't have data.
Are you using the 8/128 Chinese version in the US? Is the 4g LTE connectivity good ? I' d like to purchase the Chinese version since it has more RAM and use it with t-mobile but I see that the international version supports a few more bands but only comes with 6 GB of RAM.
I live in ireland, i have the 8GB ram china rom version. Now running eu rom.
See even if 4g goes i can use mobile data with 3g?
If i purchase mobile data for sim 1, i can browse the web and have a call and vice Versa with sim 2.. i dont think its todo with volte, i think its because im on a call with like sim 2 and the phone doesnt no to use sim 1 for data?

No data connection on second sim after Android 10 OTA

4G LTE data works on both sim slots but only 1 at the time and only on the sim slot that i have set as the preferred data slot. Does anyone else have this problem?
When i make or receive a phone call on the secundary sim (not the primary/preferred data sim) i lose data connection. The primairy data sim is then automatically switched off. I have of course the Enhanced LTE toggle switch ON on both cards in network settings but this does not seem to work properly.
When i make or receive a call on the secundary sim the 4G LTE connection stays on for voice but the phone does not switch the data connection to the secondary sim card. The network connection on the primairy card is then also shut off completely. No network signal. So i cannot use internet during a voice call and also cannot receive a incoming voice call on the primairy sim.
Both network icons then show an "X" on the signal bars but strangely i keep the voice connection.
After I hang up the voice call on the secundary sim, the 4G LTE voice and data connection comes back on the primary sim and both signal bars go come back to normal and the "X" dissappears.
When i make or receive a 4G LTE voice call and surf internet at the same time on the primairy sim there is no problem. I have a Volte connection so i can voice call and surf on the internet simultaniously on 4G LTE.
This secondairy sim slot problem was NOT a problem on Android Pie on my Mi A2 lite. On Android 9 I had 4G LTE VOLTE HD voice and data on both cards all the time always. I could receive and pick up calls on both cards at the same time and keep data connection.
After OTA to Android 10 I soon discovered this problem. I did factory reset. I switched the primary sim, switched the sims in the tray. Nothing makes a difference. 4G LTE data works on both sim slots but only 1 at the time and only on the slot that i set as the primary data slot.
Does anyone else have this problem?
