I have dual sim on the T-Mobile version. I am trying to get visual voicemail apps to work for both carriers however T-Mobile is the secondary sim and the T-Mobile app is therefore scanning the wrong network for voicemail (can't force it to go on sim 2 data on an app basis). Any suggestions?

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:

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.)
I have a SM-G955U that's GSM unlocked. It was originally an Xfinity phone, but I'm now using it on mertopcs. Mero supports active data while talking on the phone. But my S8+ disables my data while making a call. I do not have root, is there a way to keep my data while talking on the phone?
Try this settings/ connections/ mobile networks/ VoLTE Calls. I think that's the option you're looking for
That option doesn't appear when I go there...
I've checked through the phone app and the settings menu, nothing like that appears anywhere.

I think this option depends on the carrier itself you're using some carriers doesn't support vollte so this option will not be enabled by default. My carrier supports vollte.
Next to 4G or LTE icon vollte will appear like the picture below

The original carrier for this phone did not support vol LTE by the carrier I'm using now does support it. It was originally Xfinity and now I'm with MetroPCS.

Maybe flash the MetroPCS firmware or unlocked firmware.
You don't need use VoLTE to talk and browse at the same time, if your carrier doesn't support VoLTE your cell phone will perform a CS Fall Back to UMTS and then (if your carrier support MULTI RAB) your cell phone will make MULTI RAB, one RAB CS to voice and one RAB PS to data. The problem is when you are using 2 sim cards, if you make a call from one sim card and the data came from the other sim card, the Galaxy S8+ will block the other sim card in a call.
So to call and use data at the same time you will need VoLTE in LTE or Multi RAB in UMTS but must be the same sim card.
I have TMobile and Verizon sim set up. TMO is set as primary sim. Verizon sim can send texts but I am unable to receive texts on that sim. Any help would be great
I reached out to the MVNO and they refreshed the sim settings and after a restart all is well.
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.
I have an unlocked S22U (purchased directly from Samsung) and I am trying to get dual sim set up. I have an eSIM setup currently which is functioning as expected. I get calls, messages, and 5G no problem. I have a physical SIM which also works fine; calls, messages, 5G. However, they only work if I disable one at a time. With both SIMs inserted, I only get 4G data out of the physical SIM and no data at all from the eSIM. If I set the eSIM as my primary SIM, it acts like I have no data at all.
I honestly have no idea what to think, does anyone have any input?
eSIM - Mint
Physical Sim - Visible
It sounds like a settings issue. Look under connections / mobile networks / network mode. Are they both on 5g? Also are you dual SIM both active in sim card settings?
