About Dual Sim - Second Sim For 2G - Edge Connection

Hi,
Is there any option, hacks, settings or customised rom or something for second sim card's 2G connection (it says supports edge connection) ?

Second sim does not support any data connection only 2g calls, only sim 1 supports data enabled

Second sim surely can support data but will need some deep hack because you will first enable modem to allow data connection and second at OS level some tweaks.

Thanks for your suggestions but anything else?
There must be a real solution, i'm gonna search deeply about this.
Thanks anyway

Dual sim management and hotspot support

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.

Dual SIM Hotspot - Hotspot on one sim while other sim is active data?

Is there a way to have one sim default for hotspot, and the other default for data? I have 2 sims, one personal with unlimited data, no but no hotspot. The other is a work sim, with a fair amount of data, and tethering allowed. I would like to have my personal sim (sim1) as default for data, but when I tether, have to tether on the work sim (sim2). Is this possible, or can only one sim be active for data at a time? My workaround so far is to have the sim switch and hotspot both in my quick settings and tap one then the other when I am turning on hotspot. My fear is that I will forget and tether too much on my personal sim and get caught by the carrier.
Thanks!

VoWiFi over second "data SIM" - is it possible?

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 ?
