Did anyone have dual sim problem? Mine was working, but recently if I use one sim to make/answer call, the other disabled. The other icon show hourglass icon, and data connect lost.
I have Tmobile 4G & ATT GSM.
Data goes TMO.

Hi
I have a Zopo ZP950+ with Etotalk ROM, from China, it is a 5.7inch Phablet running stock JB, with Quad Core and DUAL SIM.
http://www.etotalk.com/zopo-zp950-16g_p3854.html
I am in UK, with UK SIM installed (T-Mobile), so at moment not roaming, but phone constantly tells me I am roaming.
I want to use the full 3G/HDSPA connectivity so do not want to disable data.. Under Settings/More/Mobile Networks, there are no options for roaming settings to change, though there is a "data connection - off" option, but I don't want to turn data off, and the roaming warnings are intrusive when sending texts or making calls.
If I can''t "fix" the fact that Roaming indicator is constantly on, even though phone is not roaming, can I hide the warnings every time I make a call or send a text?
Any 3rd party apps out there to help?
Thanks
While I wait for an answer, I will add this: I just tried a giffgaff SIM using O2 network, all is fine, seems to be a problem only with T-Mobile SIM, called T-Mobile they said I needed a replacement SIM card, but this SIM is fine in 2 other un locked (though not Dual SIM) handsets.

Hi there I have the same issue with my Star Note II N9599 and it too reverts to Roaming and I use Orange UKeven though its now part of EE Network UK but I did find out that the handset is actually Roaming! To check this go into Dial Pad and type *hash*hash3646633hash*hash* then goto Connectivity then down CDS Information the to Radio Information then to Phone 1 and you can see if the Sim in slot 1 is truely Roaming or Not?
I have yet to find a fix for this issue but did also stumble across my Associated Network Radio Bands as follows:
GSM MODE ( SIM TRAY 1 & 2 )
EGSM900 (selected)
DCS1800 (selected)
PCS1900 (selected)
GSM850 (selected)
UMTS MODE ( SIM TRAY 1 ONLY )
WCDMA-IMT-2000 (selected)
WCDMA-PCS-1900 (greyed out)
WCDMA-DCS-1800 (greyed out)
WCDMA-AWS-1700 (greyed out)
WCDMA-CLR-850 (selected)
WCDMA-800 (selected)
WCDMA-IMT-E-2600 (greyed out)
WCDMA-GSM-900 (greyed out)
WCDMA-1800 (greyed out)
WCDMA-1700 (greyed out)
Now at best guess I take it these settings are not correct for the U.K.
If this is so then which BANDS Do I Need and how do I go about changing the greyed out ones that I cannot select to be selected as a usable Radio Band?
I have looked as best I can on Google etc but Im all new to this and not entirely sure what to look for or how to do it if possible?
I have read other sites of users being able to change the Radio Bands for other types of Handsets so I know there must be a way?
I still have the issue where I can set my phone to Register on the Orange network and it connects and gives me 3G with Data but soon after the connection decides to reset to Roaming and drops Data unless I choose to select Data Roaming?
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.)
Good evening I turn to you because I have a problem with my slot sim 2 I do not have a 4G. When I activate it I have no network. Roaming and any other settings sound activated. At least I hope so.
Although the phone tells me that the network is available, I can not call or receive calls (same for SMS). On the other hand, a priori, no problem to access the internet via 3G. When I try to call I have the following message: Mobile network not available
Help me
Have you tried any other SIM?
You need to go into your mobile network setting and Dual Sim setting to make sure Sim 2 is active.
Now if you want Sim 2 to use 4G you will have to select this in the Dual Sim setting. By default Sim 1 is the default mobile settings.
At any one time 2 sim are in the device only one will use 4G or 3G the other will use 2G.
here are the tests I made with reboot

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?
