[Q] Problem concerning Dual Sim phones with Data plan

Hi all ,
I am having a problem that is annoying me for a long time now , some friends have fixed this problem in their phones but don't know how , my last hope is XDA ...
I have a mob with dual sims , SIM1 is my default SIM where i do all my calls from and does not have data plan on it , SIM2 has a data plan , the problem that when I activate data plan in SIM2 , anyone calls me on SIM1 gives him that phone ( SIM1 ) is out of coverage area !!!!!! plus that the data plan on SIM2 is extremely slow and takes forever to load a page with connection error at the end .
my phone is Hisense U5 , i know it is not common phone , so I am buying Samsung Grand in very few hours and knew that it has same problem but it can be easily fixed , I dont know how to do that and indeed need a help before buying it .

Hi, I guess you need to put your data plan in SIM1 slot and your calls and sms in SIM2. SIM1 slot supports 3G while SIM2 slot supports 2G only. Thats the reason why data is so slow.

[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.)

Galaxy S6 Duos Network Issue

I need to solve an issue pertaining to my Galaxy s6 duos. The problem is that sometimes my phone's sim 2 wont work, although it is registered on the network but it won't make a call or send a message neither would it receive a call or message. After i put the phone in airplane mode and switch it back online,then the sim2 starts working. Please help me in solving this issue. What could be causing this problem?

Hmmm set sim 2 only to 2G network and check if it losse connection... (I suspect when phone leaves a 4g area and it has to connect to 3g sometimes stuck at searching ...)

I have an issue that whenever i use mobile data on sim 2 it connects to 2g. I need all the time to go and change from 3g/2g to only 3g then back again to get 3g working. Also noticed that if 3g is not in range it switches to 2g but when its in range it does not automatically take 3g.
