I just upgraded my SM-A700FD to Android 6.0.1 and had trouble with Dual SIM operations.
My SIM 1 is on LTE data whereas SIM 2 has no data. Whenever I make a call on SIM 2 (incoming or outgoing) my data connection on SIM 1 is lost. I have enabled Dual SIM Always On in SIMCard Manager under Setting.
I tried in Safe Mode and still the same. Does anyone has the same issue? This seriously render the Dual SIM phone unusable.
The SIM Card Manager also force SIM 2 to 2G if SIM 1 is set to LTE/3G/2G (Autoconnect), even though my SIM 2 is on 3G network but using only voice and text.
When I am using data on SIM 1 to browse or running Apps, I can receive SMS text on SIM 2 without interrupting SIM 1 data, but as soon a voice call is established on SIM 2 the data on SIM 1 is lost.
Would appreciate it if anyone can help.
Thanks!
Hey Guys
Here is the deal..my G935FD is having connectivity issues (service unavailable) on the SIM card that provides backup mobile data but only when on 2G network. My assumption is that this carrier have move away from 2G and have limited connectivity capabilities in 2G. When switched to 4G, works just fine... however I want to use this carrier only for voice services and not data.
I already updated my modem to latest version with same results.
My goal is to disable data completely on this SIM, but the minimum setting on the Edge is 2G and on top of that is not possible to have both SIM running 3G/LTE. I also tried using a fake APN but no luck.
Do you know a way to accomplish this?

From what I could understand, you want mobile data on your primary SIM, and use the secondary SIM only for voice but the carrier is re-farming 2G and you can't have 3G on the 2nd SIM slot?
Well, there's no solution for it. One SIM Slot can do 2G/3G/LTE whereas the second one can only do 2G. No way around it.

Thanks for your help. So no way to only shut down data completely on the second SIM? Shutting down mobile data from settings shut it down for both SIMs, couldn't find a way to shut them now independently.

Under SIM card manager, when you see the Mobile Data tab, isn't it set to SIM 1? That would automatically disable Mobile Data on the 2nd SIM, however you can't get past the network mode restriction. So SIM 1 will be on 2G/3G/LTE, whereas SIM 2 will be on 2G only.
Very easy
Via the settings tab, get into mobile network tab, select access point names.
Choose the sim u want to deactivate and then select the APN and delete it with the menu option on top right hand corner.
using 3g doesn't mean it will use data.. when u chose the primary sim for data the other will never use data even on 3g.
Hi All!
I own a Lenovo K6 Power as you can already tell,
in which the Data functions were working without any issues.
A few months back I started using 2 sims instead of 1. Since one carrier had faster internet and better connectivity than the 1st.
Still using the 1st SIM for calling and 2nd SIM for data. Occasionally I would switch to the 1st SIM for data when my data pack was over for the 2nd SIM etc...
So one fine day, I was switching back to SIM 2 (Sim I use for data) (Normally when you switch SIMs both deactivate and reactivate with new settings ie SIM 2 for Data).
So while this was happening like usual it took a few seconds to switch SIMs in the midst of this I suddenly got a call...
Which I was unable to answer till the buffering animation left my screen.
When that did get over... Both my SIMS were set to EDGE 2.5 g when they were always recognised as HSPA 3G and 4G LTE for SIM 1 and SIM 2 respectively.
Now I am unable to attain the speeds I used to, it is just barely usable now...
I then tried the usual troubleshooting (Airplane Mode on/off, Deactivating / Reactivating SIMs, Swapping SIMs physically from their slots and Finally Rebooting...)
Now when I recently tried doing the same my 2nd SIM which I usually use for Data appears as SIM Card Not Ready...
However, when I individually insert SIM 2 it is read by the phone
But still, whether I individually insert the SIMs or together the phone recognises both the SIM cards as 2.5g EDGE.
They used to be HSPA 3G and 4G LTE.
But now I can't use Data on my phone which is the major problem...
Please Help
Reset ur phone.
Is there any other option?
Apart from this...
I don't want to lose my data.....
What if that doesn't solve the problem...
Is there a way to in Sm-g935fd running LineageOS 14.1 to completely disable a Sim card like in the original Samsung firmware. I run 2 sims and want to switch between data after I use up the data for one of the Sims. When I try using Sim card 2 for data it will not connect or will not connect with a data connection and keeps trying to use Sim 1 even with the data turned off. I don't think it matters for this but I'm using FreedomPop which uses at&t.
I have the latest firmware update, and I'm using it with 2 SIMs; Sim #1 is a Google-Fi on roaming, and Sim #2 is the local default sim. I choose SIM 2 to be the default for everything (calls, SMSs, and data). However, I kept seeing the mobile for some reason switches the data to SIM 1, however, I disabled data roaming, and surprisingly, the mobile still randomly changes to SIM 1 (Google Fi) and also consume data!!
