Hi guys, I wanted to open this thread to expose the quite strange behavior I am observing on my oneplus 3.
I use two sims. Both have 3G and LTE fully compatible with op3 bands.
Here is the behavior I am witnessing:
1) Let say I start my phone with data enabled on sim 1.
2) phone starts I have data on sim 1 no data sim 2.
3) I start tethering using the wifi hotspot feature. I connect either with an iPad or W7 or W10 laptop
4) devices can access the Internet using op3 hotspot.
5) now I deactivate hotspot. I switch sim data from sim 1 to sim 2.
6) after a minute or so sim 1 no longer has data enabled and sim 2 has 3G/LTE access through the phone.
7) I switch tethering back on.
8) none of my devices are able to access the internet despite having internet directly with the phone.
Only workaround is to restart the phone with data on sim 2 enabled in order to get data access using tethering on sim 2
Based on my experience, is this an expected behavior?
If choose I tried switching sim slots but no luck. I am questioning myself. Is it an issue on one of the sims or Wirth thé phone?
Anyone had a similar experiencece to share?
Thanks
I've been having a similar issue:
OP3 with OOS 3.2.7.
I have two 4G SIMs, one 3 UK and one EE UK. I can use data (3G/4G) on either without issues and swap between them via the settings on the phone, no problem. I can tether on the 3 UK SIM no problem, both with and without the EE SIM in the second slot or first slot.
The EE SIM will not tether at all in the phone, no matter if it is by itself, with the 3 SIM, in slot 1 or 2, but the SIM does work and tether in my trusty Nexus 4.
I've checked the APN settings and done a network settings reset (Settings > Backup & reset > Network settings reset) but nothing helped.
There's a similar thread on the OnePlus forums here.

i have been experiencing several problems with S4 mini 9192 since i bought it one month back and one of these is that the phone does not switch data between the 2 sims correctly.
to have the data work correctly on any sim, all the below must be done
1-select the sim you want to use for data in sim card manager/data service network
2-have the same sim configured as gsm/wcdma (auto connect) on connections/more networks/mobile networks/network mode
when you select option one, the phone tries to perform task 2 too, but fails, thus the data sim is left in "GSM only mode" and will only have edge data, never connecting to HSPA/ 3G.
here is what i have to do each time to switch data from Sim-1 to Sim-2 (screenshots attached)View attachment Screenshots.zip
Screenshot 1- you will notice data is set for sim 1 and HSPA is active
Screenshot 2- select sim 2 for data
Screenshot 3- the phone will disconnect data on sim 1 to switch
Screenshot 4-phone will try to set sim 2 as "gsm/wcdma (auto connect)"
Screenshot 5- but gives alert message and fails
Screenshot 6- sim 1 is still on "gsm/wcdma (auto connect)" and the data connection for sim 2 is only edge
Screenshot 7- Sim 2 is still on "gsm only" and does not connect on hspa no matter how long you wait
Screenshot 8- for data on sim 2 to work properly, first change sim 1 to gsm only
Screenshot 9- then change sim 2 to "gsm/wcdma (auto connect)" and wait for 5 seconds, the phone will connect on HSPA .. success
now my big question is, does this happen to everyone with s4 mini 9192, or is it just me??
by the way, this occurs on both my Egypt stock firmware and the j2 india firmware i just flashed.
i tested a friend's Galaxy Mega 5.8 Duos, and the phone performs both steps by itself, with no need to perform the 2nd step manually.

I have had the same problem with my model that I bought in Australia. Your solution worked well for me as this is one frustration that I've been blaming on the network rather than the phone for the past week (because I was ignoring the error messages). I would hope a software update is in the works to fix this issue as it will get quite annoying in time.
I have the very same issue, plus the second sim slot only work in GPRS, and I try 4 rom before getting block by ****ing knox problem.
Sorry to dig this out but i havent found any answer to this yet.
is there any way to get a widget or a script or anything so that one can easily switch data connection from one sim to the other by one click? Or even automatically depending on which sim is in its home network?
This would be awesome as i'm hopping across the border twice a day and switching data connection all the time is a pain in the a**.
Thanks a lot for any answers!
I am also looking for answers for this.
Out on the site I work at they only have 3G towers but I have no data access on my work phone so I need to use my personal sim for checking email, then switch back so I can use work phone again.
Known issue on the phone it sucks

Thanks for posting this, finally i can have 3g on sim2!
Hey champs,
I got a strange issue with the swift. Last year I bought 3 Swifts for my wfe and kids. All of them equipped with two SIMs (1&1 for wired phone connections only, Simyo for cheap data flatrate and calls to mobile phone numbers). All phones have been upgraded to Android 6 so far. We use dual sim selector pro to do the call routing to the correct SIM, works like a charme. But regardless what I set in mobile data settings, after reboot the mobile data will always connect to 1&1 mobile networks (in fact it is vodafone) giving us one time a very high bill.
In the meantime I amended the vodafone APN to get rid of it, but this only leads to the situation, that after a reboot there is no mobile data at all. And since my son's phone is locked by funamo parental control, he is even not capable of swithcing mobile data by the settings.
Is there any chance to make the setting permanent? Is there any API call available, so I can get it managed e.g. by tasker? Is there an app available, that deals with data settings on dual SIM phones with Qualcom chipset?
Tnx in advance!
Glad to see I am not the only one with a problem, I live in Spain and use Orange SIM for data and voice, I also have a tesco voice only SIM which I use when in UK. Fine. I have exactly the same problem after a reboot or flat battery, "No Data Connection" when I check the settings it has changed to Tesco (which does not have data) Its only the data scource SIM that changes - voice and SMS remain as Orange. It is very annoying.
Same problem here with stock Android 6.0.1 Cyanogen OS 13.0-ZNH0EAS2NH and EE sims in slot 1 and 2... (one work and other personal).
Was thinking of returning phone, but apart from this problem, I really like it.
Latest Cyanogen OS update, (just installed), appears to have fixed my problem...
I updated, did a battery pull just for good measure, and with several restarts, the correct SIM appears to be selected each time.
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.
Hey!
My network operator supports VoWiFi feature, which i'm using a lot. I'm traveling quite often and using VoWiFi i can use voice services using domestic prices worldwide.
I have dual SIM card phone, in the second slot i have data sim.
Here the question comes - is there any way to configure a phone to use VoWiFi feature over data connection from the second SIM?
Essentially VoWiFi feature requires just internet connection, so in theory such approach should work, but do not know if it is possible to configure the phone this way.
Would appreciate any help
Gentlemen,
Any help would be appreciated.
I do have workaround - to use the second phone, share WiFi from it and then i can use VoWiFi on my main phone. But it' super inconvenient - you always need to care 2 phones.
If you know any apps/solutions please let me know.
I have dual SIM and I am able to have Wifi Calling enabled on both SIMs at the same time.
However - you are talking about VoLTE if you're talking about using the data connection on the second SIM rather than a WiFi connection.
Again, however, this should be possible - I can enable VoLTE on both SIMs. It's under Mobile Data in the Settings app...

VoLTE is different technology and is charged in my case differently. That's the reason i'm looking for an option to use data sim that the main sim uses this data connection for the call simulating "VoWiFi" and hence use domestic rates for the calls.
As i said above i can emulate this with two phones, but i still hope to find a solution where i can archive that with only one phone.
I'm looking for the same solution. My note 8 is rooted. The best I can do is set WiFi Calling as preferred over Network calling, but as soon as I activate Data for SIM#2, I lose WiFi calling and VoLTE for first SIM. Very inconvenient. Anyone have any clues how to force WiFi Calling using Data of SIM#2 ?
Hi guys just got redmi note 8 pro and almost every time I go out of reach of wifi my mobile data doesn't work. It happens also if I manually tuen off wifi. I have the H+ icon like it is connected but I don't have data connection. The issue is resolved if I go in and out of airplane mode then I have data connection again. If I just turn off and on data connection in the quick settings it does nothing. APN settings are set and working ok.
MIUI global 11.0.3.
did u find any solution.....
if you are using any 3rd party VPN or using custom DNS then please disable them and try again.
I had the same issue. I emailed Xiaomi's support and also posted it in the Mi community forum. Followed everything (except factory resetting the phone) but nothing was working.
Finally, I was able to find a solution that has fixed this issue for me (I've spent almost a day and haven't experienced it yet).
I was using a single SIM card on my phone. My SIM card only supported 3G network. After trying all the solutions, I grabbed another SIM card (of another network provider) and put it in the second SIM slot. This new SIM card also supports 4G LTE.
At this moment, my phone has 2 SIM cards. One supports only 3G and the other also supports 4G LTE. Though my default mobile data is still set to my original SIM card (3G).
After using two sims simultaneously, I've not experienced this issue again.
So I assume that Redmi note 8 Pro has a bug that doesn't allow mobile data to work properly if there is a single 3G SIM card present in the phone.
I have the same issue.
Works for sometime then suddenly no internet even when it's showing 4G+ sign. I have to turn off the data then on again to get it working which is annoying.
Same issue even with dual sim installed.
