[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:

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.)

Unable to make calls when data is on

Mobile data not working during call

Hi
I am having an issue with mobile data being turned off during a call. I have a dual SIM S8+, when I call on sim 1 the data on sim 2 turns off.
I have it set up that sim 1 is calls and texts and sim 2 is mobile data.
Any ideas how to fix this
Thanks
S8 is dual sim dual standby and not dual sim full active, so when one sim is active on a call the other will be deactivacted and cannot receive calls or used for data at the same time. It is not an error and it cannot be fixed.
Thank you for that. If I just use one sim on the phone. Then will I have data active while calling?

If you have data set to sim 1 you will have data during a call on sim 1, but not while on a call on sim 2, and vice versa.
If you only have one sim in the phone, you will always use the same sim for data and calls, so you will not luse data.

Dual SIM

When traveling, I want my home SIM only to keep my Whatsapp number; I don't want it to use any data or calling. How do I configure SIM2 for everything, SIM1 only to ring (but not answer)?
Just select the other sim for data as primary or 4G and it will work fine for your WhatsApp number.
See mine, i am using sim 2 for whatsapp and sim 1 for data, calls etc

Sim 1 stopped working note 20 ultra d/s

Hi guy. On my note 20 ultra, sim1 stopped working. I thought was network issues but it wasn't. When I put on sim slot 2 it works, when I change sims around sim 1 won't register to a network. If I activate wifi calling, I can make calls from that sim. I have even check status of my imei, and is not blacklisted. (I have wiped cache partition, I have reset network settings, I have rebooted, I have deactivated Sim tray and reactivated again) have anyone experienced this issue?
something for Samsung technical support to look into
