Hi and a happy new year everyone
I'm trying to use my tablets SIM which has rather good internet capabilities as my second SIM (SIM2). My main SIM (SIM1) is used for calls/sms.
I'm from Scandinavia. SIM1 is 3, SIM2 is Telenor.
SIM1 is being used only to call/sms.
SIM2 is used for internet.
I can't chose 4G/3G for both networks, only one.
SIM1 doesn't work with 2G network (emergency calls only problem) only 4G/3G, but that leaves me using SIM2 with only 2G, which defeats the whole purpose.
Where is the problem? Is it a phone or provider issue?
Hi guys,
For anyone with a dual SIM model of the LG V20, can you please do myself and others a big favour?
I need to determine the phones capabilities and functionality when it comes to dual sim capability. We know this is only dual standby, but I need to determine a few things. Can someone please answer these questions ONLY if you have this phone and ONLY if you've tested it?
1) Can a 3G phone (voice) call be received on a SIM whilst the other SIM's 4G data is in use (Y/N)?
2) If yes, does the 4G data SWITCH OVER to the other SIM to allow that voice call to come through, or:
3) Does the 4G data temporarily cut out on the "data active" SIM for the other SIM to allow inbound 3G voice call?
4) Can you deactivate test to confirm with 100% accutracy only 4g and/or 3G is being used on both SIMs?
Any help from current users (or if anyone can post a video oft he settings/functionality), that would be awesome!
Thank you

Please don't all jump up at once.

Hi. Cant exactly verify this because in the Phillippines H990DS. We dont have voice call over 3G.
But if it helps, i have a viber account on SIM2s number. I use SIM1 as Data provider.
When i get a viber call on SIM2s number, it doesnt switch but instead uses SIM1s data.
But not entirely sure if that works the same as Voice over 3G
When one sim is in use the other is disabled, I think the only phone that does this is huawei mate 7, but that's 4G+2G or 3G+2G.

Not entirely. Yes, they are dual standy by...but when 4G is active on SIM and call comes in on SIM 2, it should eityhert SWITCH the data to SIM 2 to allow call to come through, or temporarily disable 4G on SIM 1 for the call to get through. See other models that dpo this:

This phone has the new chipset that can allow this. Have you actually tried this, or have any images to confirm your findings?

You have the HK model, right? Makes no sense why two dozen or more other models out there with this chipset can allow 4g/3g (evenif 1 is temporarily disabled) and this new flagship doesnt.
i got the H990DS today. I have Tmo and AT&T. it has 3G standby. No matter which SIM i select in 4G the other always holds 3G.

Perfect. Thanks for confirming. Sorry to be a pain in the butt but could you screenshot that on the phone and post to confirm {if signal at top left status bar shows this}?
Sent from my LG-H818 using XDA-Developers mobile app
Sure thing. :good:
..
here is my findings for a few days, i bought a data sim card (only internet) and added to my LG V20 as SIM2
1) yes, you can receive calls while the data is working on the second sim
2,3) in my case, when i receive a call from SIM1 (4G), the data SIM2 still connects between 4G and 3.5G, but in both cases the data is been cutted off and unable to do anything
(this was tested via hotspot the SIM2 and getting a call on SIM1, happened multiple occasions)
4) until now, SIM1 and SIM2 in my device works both on 4G (battery drainage is surprisingly holding up)(tested via switching between SIM1 and SIM2 Data connection)
one note to be considered, the data speed was very low, i called my provider and adviced me to switch to another device (portable router adviced), i switched the sim to another device (Note 3) and the net speed was signifacantly better for a while

Your answer is helpful, Silver Mask! Just to confirm, if I'm on a call on SIM2, I would not be able to use the internet on SIM1 at the same time? (e.g. if I wanted to use Google Maps with SIM1 sata while I have a SIM2 call on speaker). If I understand correctly, you're saying I can receive a call on SIM2 while I'm using SIM1 data but once I pick up the call, the data from SIM1 will be temporarily disabled?

Either disabled as an extream case, 50% of the time it switch to lower band (from 4G/LTE to 3G), even then the data feels slow, but usually any navigation app and social messaging apps doesn't get affected that much, it is just annoying
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...
Dear all,
I need a creative idea here: SIM 1 is my "calling SIM" , SIM 2 is data only. Consequently, SIM 2 is set to 4G. It seems though the Galaxy S8 does allow WiFi-Calling only for the 4G SIM. The setting to switch it on is not existing when the SIM is set to 2G/3G.
Any way to have WiFi Calling switched on for the 3G SIM? Alternatively, any way to use Tasker to switch profiles automatically when my Home WiFi is connected?
Cheers!
Andreas
