Dual Sim Question - Samsung Galaxy Note 20 Ultra Questions & Answers

For those on dual sim, does data on the secondary sim ever get used. In Sim Card Mgr there is a toggle to use it during a phone call but other than that , say my primary data sim is poor, I wish it would use the one with the better connection automatically but I do not think this is an option

I have a Samsung Galaxy Note, SM-N986B/DS.
No, my experience is, you can't set data usage to automatically,
But why don't you just choose Sim2, for data usage.?
While back i had 2 x Sims in my device.
(One Sim is a just a data Sim, loaded with 10 gigs data each month )
The other Sim only had 1 gig data on it, each month .)
I set my preferences as follow in Sim Manager ......
Calls.... Sim 1
SMS.... Sim1
Data ( mobile)... Sim 2
Worked fine.
No issues.
If i switched my mobile data on it would
use Sim 2 data.
However,
I have since changed my setup.
Took second Sim out of phone,
as i experience
"more battery drain" (overnight )
than when i was using
only one sim and/or sd card.
Good luck.

Yes ,it's was just the opposite situation for me ,where i had more data on Sim 2 .
However,overall i guess it never worried me, as i am 90% on wifi .
I also noticed ,more battery use age of keeping mobile data on ,than wifi.
I guess the only option left ,would be to manually, change to preferred data Sim .
As far as i can remember the best option ,
( when i had 2 Sims in my phone )
i would swipe down to expand phone quick settings
and my Sim preferences , showed ,just under the phone ,quick settings icons .
I would then long press on the preferred data Sim choice and change it there.
It was better than going all the way to Sim Manager .
Good luck

Hmmm, the battery thing is interesting. I've tried so hard to get dual sim, flashing TMB onto Unlocked but now the battery thing is a bummer. If that is what causing it. I just turned off 120 refresh rate to see if that improves battery
In Quick Settings I see where I can click on one of the sims on the top and it takes me to the sim card menu but I wish it were just a toggle instead of taking to the menu

Firstly,
Yes, only thing you can do
is "toggle" it manually, like you described.
Secondly,
with 2 x Sims in my phone
i found that my average "sleep" over night
was example......
+- 12 % battery drainage, over period of +-8/10 hours (sleep.)
Further the way i see it,
is that even with phone in
sleep mode, it still trying to get better signal reception.... x 2...? whilst
This i checked via Betterbattery app.
Secondly,
I am back on one sim.
My average sleep overnight is
8 % for 10/12 hours sleep.!
Bottom line,
It's your phone.
That battery diffs, is no big deal...
For me it was an irritating issue. thats all
If you happy with 2x sims
keep it that way!
Good luck

Previously, say I had Sim 1 for data and Sim 2 for calls and i got a call on Sim 2, then Sim 1 was unable to access data but this has now changed with N20U
If I understood this correctly then I think my device is different cos regardless of which Sim is primary or secondary, I have an option under settings>connections>mobile networks> allow all Sims to use data in calls, which I can toggle on or off. I have found selecting this allows the other sim to use data which was not possible in some earlier android versions.

But not when I'm in a call. I needed to use data from my secondary sim because I was in a dead spot for first sim. I had to go to sim card menu in settings and change primary sim and then change it back eventually. I did use the shortcut from the pull down menu but I wish I had a toggle , ideally from Nova Launcher

I am interested to purchase a SM-N986B DS for my dual sim work/personal cell in the US near NYC. I have metro PCS and Verizon. Will this phone allow verizon to operate as the second sim? It would be a non-data sim. I know it is a GSM phone and not CDMA but also read that the LTE bands may be compatible at 4g/5g. Curious before I take the dip to buy and find out it won't work...

[Q] Simultaneous Sim 1 (Call) and Sim 2(3G Data)

I'm currently using two 3G enabled Sims in my Galaxy Core GT-i8262.
My Sole purpose of getting the Sim 2 was to use 3G Data/Internet on it, while using Sim 1 for Calling and texting only.
I went for Galaxy Core only because i have to use Voice and Data on 2 different Sims separately.
Therefore , i inserted the Sim 2, Went into Sim Manager > Enabled both Sim > Dual Sim Active
I also enabled "Receive incoming calls via Other Sim card while using Data service" in Both Sim 1 & Sim 2.
But when i selected this setting i received a popup "This might slow down the data transmission"
>Also i have Set Data as "Sim 2" in Sim 1, (So only Sim 2 will ne used for Data)
And Sim 1 as GSM Only while Sim 2 as WCDMA Only
But still, when i'm on a call in Sim 1, i can't use the 3G service of Sim 2 simultaneously. Only after disconnecting the call, Sim 2 3G Data starts working,
So the whole purpose of using Dual Sim goes wast when we can't use 3G internet on one sim while on call in the other.
Can anyone suggest how to enable this feature and also to avoid the "The slow data transmission" due to Dual Active Sim.. Otherwise this phone is just a piece of trash as i'll be on call most of the time and i won't be able to check my mail or Whatsapp msgs.
Please.. Anyone reply..
Ask this to samsung CEO he cannot answer that:sly:
Sent from my GT-I8262 using XDA Premium 4 mobile app
While u r on a call on Sim 1 you cannot use the data connection from the Sim 2 even if its on WCDMA. But u can use 3G on the same sim on which the call is being recieved or done ...means Sim 1 can be used for both purpose simultaneously for Calling & Data connection on WCDMA ...even if u r on a call on sim 1 the data connection wont be lost...
hi! i'm not shure if i understand
i want to purchase this phone and i'm not shure if i can use in one sim voice over 3G and in the other one data over 3g.
I don't want to use voice and data in the same time...
Please help me
nobody can help me?
Hi Luciand, are you from Brazil?
My guess is that it is impossible to use voice on SIM 1 and data on SIM 2 because the smartphone have only one modem.
Even if it is capable of receiving calls on both SIM 1 or SIM 2, it is not possible to actively use the two SIMs at the same time.
For some smartphone to be capable of doing what you want, it should have two modems, which I believe would increase its cost and nobody would buy it...
I hope this helps, and if anyone knows better, please correct me!

You are able to select which SIMs data service the phone uses in the sim card manager under Data service network. However, you cannot use voice and data at the same time, regardless of which sim is set to be used for voice or data (at least here in the US on EDGE network.)

Incoming call not reachable in slot one when slot two sim net is on

Hi, i am using Le 1s. Using Idea sim in slot one and jio in slot two. when jio sim mobile data is on, incoming call to slot one, idea is not reachable ie. busy/not reachable/switched off tone is coming to the dialer. i even changed the sims to vise versa, but the same is happening........Anybody having solution for that?
Could you please elaborate the issue...
i.e. you get busy tone for which slot.
like if Data is on for Sim 1 then sim 2 is busy/unreachable. That is you telling.
Cause in Leeco 1s Jio will not work in Sim 2 Slot. Cause its GSM not VOLTE.
Solution: Go to phones default dial pad and press #*#*3646633#*#* i.e. *#*#engmode#*#* in that Telephony>Mobile data service preferred and uncheck the box. Now restart the phone and check.
Do let me know if you need more help.

Dual sim settings problem

Hi. I`ve got an MHA-L29 and I`ve got a problem with dual sim settings. In dual sim setting menu if I select default mobile data (4G services associated with default SIM) on SIM 1 then I lose the signal from that sim (Emergency calls only) and I`ve got SIM 2 signal. If I select default mobile data on SIM 2 I lose signal from that sim and I receive signal on SIM1. Basically, I can`t have both sim working (network signal) because I need to set 1 SIM on default mobile data and the one that I set it`s losing signal.
Maybe someone can help me. Thanks

This is strange behavior.
By default there is no problem. See my screenshot.
I suppose it is mobile operator's problem.
What is your full version (settings / about phone / build version) ?
What is your country and mobile carriers?
It`s not a mobile operator problem. I use the same sims on mate 8 and it`s fine. It`s exactly like in your screenshot, sim 1 default mobile data and I lose signal, and I have signal on sim 2. If I select sim 2 default mobile data I lose signal on sim 2 and receive signal on sim 1. So basically I can`t use dual sim and mobile data.
I`m in UK with BT and Lycamobile.
Build version was MHA-L29C432B198 but I`ve tried different things and now I`ve got nrd90m test-keys.

Agree, C432 region is for UK too. So your bug must not exist, but it is here.
Nrd90m test-keys means that metadata from oeminfo does not match with current ROM.
Did you try to rebrand? If yes, just flash ROM again what you flashed last time.
I`m trying now to rebrand, watching tutorial but I`m stuck at
After device enter TWRP, connect to USB cable.

Something blocked adb. Maybe HiSuite. Turn it off, then check that pc recognises device.
adb devices
You can issue to refresh adb
adb kill-server
Phone must be in twrp.
I`ve managed to do all the steps, but after restart I can`t get past the Huawei logo, phone enters in Huawei eRecovery where I have Download latest version and recovery (restore your system with wifi) reboot or shutdown. I`ve tried to restore the system with wifi but I can`t (getting package info failed). I don`t know what went wrong during the process but the phone it`s stuck at huawei erecovery.
So now I`ve managed somehow to update emui to 8.0 and android 8.0 and I have build number MHA-L29 8.0.0.321 (C432log), but the initial problem it`s still there.
I still can`t use mobile data or both sims in the same time. The sim selected to be default mobile data lose signal.
I`ve tried to use 1 sim and sdcard but I don`t have signal because the sim it`s set by default to be mobile data.
Anyone?

Seems to be hardware issue. Do you have warranty?
I don`t have warranty. Both sims slots work fine one at the time, not together.
I need 10 posts on the forum so I can upload a screenshot.

OK. Last thing - try to delete and recreate apn settings.
Don't think that they all incorrect, but maybe one of them...
The Mate9 is active/passive: it's impossible to make a call using sim 1 and using mobile data with sim2 but in stand by you can receive calls on both sim. This limitation is not present on mate8 and mate10.

I`ve tried other sims, put new apn and it`s the same.
pgmunzi I can`t because I don`t have signal on one of the sims. In dual sim settings, I need to set sim1 or sim2 to be default mobile data. With sim1 set on default mobile data, I`ve got signal on sim2 and no signal o sim1 (emergency call only), not even to receive. With sim2 set on default mobile data, I`ve got signal on sim1 and no signal on sim 2.

You can only have data on SIM1. Both sims can be used for calls and SMS (to my understanding). If you have two SIM cards from the same network it should not be a problem, overall. If you have two different networks (one on each SIM) then you might have some issues.
If you have the SIMS on the same network, and they use the same APN, you might want to copy the settings to two different APN's a label them for SIM1 and SIM2.
Also be careful of what version of OS you use. If you download a version that is originally branded for something else, then expect problems. There are also "Gotcha's" with firmware that is taken from one device and reconfigured to work on your device. Usually this is a matter of rebranding and copying underlying code over. This too causes issues with dual SIM phones. I have found this to be true with my MHA-L29C567. Sadly, I would love to have a memory card under the second sim slot along with a second SIM, but I have yet to figure that one out...

Just got the same problem (2 sim cards from same network, only obe working at a time) and thanks to you it's solved. I just had to rename the second APN differently.
I have the same problem. Is it solve? Hv been searching for solution.

hi i just wanna ask if uve solved this, Im currently facing the same problem
my both sim are working fine but some time one sim card not work when i reinsert sim. it does work. so what is the issue?

telephony and data connection

i have two 4G sim cards
when i make a phone call on my secondary sim (i.e. the one that is not used for data connection), i lose my data connection on the primary sim.
is this the normal behaviour?
Yes that's normal.
Unfortunately, all dual-sim phones today are dual stand-by which means that they only have one modem and only one sim can be active at a time. In dual stand-by, if one sim receives a call, the other is disabled automatically till the phone call is ended.
What you are asking about is called dual-active which means both sims can be active simultaneously and can receive calls and data on both sims at the same time, which requires the phone to have dual modems. The last phone that had dual modems was the Huawei Mate 8. Today, unfortunately, they don't make dual modems anymore. I don't know if it's due to health reasons or some regulatory restrictions.

Dual SIM VoLTE Verizon and Fi

Hi all,
Here is my situation and problem. I have 2 Sims:
SIM 1: Google Fi - my personal number, I want to use it for phone calls only even though it has a small data lan
SIM 2: Verizon - work sim, I want all the data to go through here.
My setting is phone call sim 1 and data Sim 2.
When I make a phone call via SIM1, I lost LTE on my SIM2.
I did call Verizon to get the CDMA LESS feature turned on.
If I were to change the setting to phone call and data through the same sim, then VoLTE works just fine. So I think this is an issue with the phone itself/settings.
Thoughts?

You need to go into settings "SIM & network settings".
Select "Dual 4G networks".
I don't have your issue.

I have a similar problem. Voice on SIM1 data on SIM2 different carriers. Receive calls and text OK answering won't work. Roaming in Europe. Worked OK prior to recent update. Same setup works on Samsung S10e

Can't believe there are so few of us having this issue. Why would the LTE turn off when I'm not even using that sim?
Probably many are using just a single SIM.
Have you tried switching the sims in the slots?

I have no help. In January Mint had an issue where their SIM had to be in slot 1. So I flipped SIMs. Truphone won't work either.
