ZE551KL - Data Service only available on 1 SIM

Help!! I just got the phone and i have 2 AT&T SIM cards installed only the sim that i select as preferred data sim gets data service. Second sim card only receives 2g cellular service. which is ok other than the following 2 things. MMS messages need data service to work correctly and 2g cellular service is horrible in my building at work. I have tried manually selecting network but only available option for secondary sim is 2g. also tried manually setting up a new APN but didn't seem to change anything. my data connectivity and cellular reception flip when changing preferred data sim . so i know its not a sim card issue
I am not rooted
os = 5.0.2
build LRX22G.WW
KERNEL = 3.10.49-gaa8154f
1.16.40.763#1
baseband version = 202c10_10_10.0.0_151106

Do you have the option to set the preferred network type for both SIM cards separately?
It's under Settings > More (Under Wireless & networks) > Cellular network settings > Preferred Network Type
I only use 1 SIM so I can't see what additional options are available when you use two.

No preferred type is for both i have it selected to 4g/3g/2g i can select the network operators independently. once i search for network one sim gets 4/3/2g options and the second only get 2g as an option. AT&T and Tmobile are showing up

Hmm wish I knew more about this to help you out but I don't have any experience with running two SIM cards in a phone.
Have you used both of these SIM cards in another phone before and had them both work as intended simultaneously?
It could just be a limitation of the phone, maybe it can't have two separate 4G connections at once on the same network?
I'm just throwing ideas out there.

Well I am having a similar issue, I have a bell sim I would like to run as 2g and a koodo sim I would like to be the full 4g. The phone refuses dual active, only card selected for data connection functions; I can choose either, but only one functions at a time except for a couple minutes after switching via dual sim settings
---edit---
I forgot to mention, it activates during a call as well

The phone specs say it can only connect to a LTE/3G network on one SIM at only one time. The secondary SIM can only connect to 2G-GSM.

Given the phone specs. Your connection problem is caused by neither Telus(Koodo) or Bell have a 2G network. Yeah so the phone is pretty much useless to Canadians if you want Bell/Telus/Wind/Videotron on the secondary SIM.

I have used my phone (same model) with two SIM's (ATT and T-Mobile). You can enable data only on a device at a time, but it can be on any of the two SIM's. This is mentioned in the phone specs.

Scroll down to the end note.
Other phones cannot even activate the 4G on the secondary SIM.
It's a little confusing maybe to switch the data, but it can be done - from Android settings.

Ahh, well its still a sweet phone; manually switching isn't a big deal

*DUAL SIM* LG V20 users: Please test 4G/3G capabilities and report your findings...

Hi guys,
For anyone with a dual SIM model of the LG V20, can you please do myself and others a big favour?
I need to determine the phones capabilities and functionality when it comes to dual sim capability. We know this is only dual standby, but I need to determine a few things. Can someone please answer these questions ONLY if you have this phone and ONLY if you've tested it?
1) Can a 3G phone (voice) call be received on a SIM whilst the other SIM's 4G data is in use (Y/N)?
2) If yes, does the 4G data SWITCH OVER to the other SIM to allow that voice call to come through, or:
3) Does the 4G data temporarily cut out on the "data active" SIM for the other SIM to allow inbound 3G voice call?
4) Can you deactivate test to confirm with 100% accutracy only 4g and/or 3G is being used on both SIMs?
Any help from current users (or if anyone can post a video oft he settings/functionality), that would be awesome!
Thank you
RoOSTA

Please don't all jump up at once.

Hi. Cant exactly verify this because in the Phillippines H990DS. We dont have voice call over 3G.
But if it helps, i have a viber account on SIM2s number. I use SIM1 as Data provider.
When i get a viber call on SIM2s number, it doesnt switch but instead uses SIM1s data.
But not entirely sure if that works the same as Voice over 3G

When one sim is in use the other is disabled, I think the only phone that does this is huawei mate 7, but that's 4G+2G or 3G+2G.

Not entirely. Yes, they are dual standy by...but when 4G is active on SIM and call comes in on SIM 2, it should eityhert SWITCH the data to SIM 2 to allow call to come through, or temporarily disable 4G on SIM 1 for the call to get through. See other models that dpo this:

This phone has the new chipset that can allow this. Have you actually tried this, or have any images to confirm your findings?

You have the HK model, right? Makes no sense why two dozen or more other models out there with this chipset can allow 4g/3g (evenif 1 is temporarily disabled) and this new flagship doesnt.

i got the H990DS today. I have Tmo and AT&T. it has 3G standby. No matter which SIM i select in 4G the other always holds 3G.

Perfect. Thanks for confirming. Sorry to be a pain in the butt but could you screenshot that on the phone and post to confirm {if signal at top left status bar shows this}?

Sure thing. :good:

..

here is my findings for a few days, i bought a data sim card (only internet) and added to my LG V20 as SIM2
1) yes, you can receive calls while the data is working on the second sim
2,3) in my case, when i receive a call from SIM1 (4G), the data SIM2 still connects between 4G and 3.5G, but in both cases the data is been cutted off and unable to do anything
(this was tested via hotspot the SIM2 and getting a call on SIM1, happened multiple occasions)
4) until now, SIM1 and SIM2 in my device works both on 4G (battery drainage is surprisingly holding up)(tested via switching between SIM1 and SIM2 Data connection)
one note to be considered, the data speed was very low, i called my provider and adviced me to switch to another device (portable router adviced), i switched the sim to another device (Note 3) and the net speed was signifacantly better for a while

Your answer is helpful, Silver Mask! Just to confirm, if I'm on a call on SIM2, I would not be able to use the internet on SIM1 at the same time? (e.g. if I wanted to use Google Maps with SIM1 sata while I have a SIM2 call on speaker). If I understand correctly, you're saying I can receive a call on SIM2 while I'm using SIM1 data but once I pick up the call, the data from SIM1 will be temporarily disabled?

Either disabled as an extream case, 50% of the time it switch to lower band (from 4G/LTE to 3G), even then the data feels slow, but usually any navigation app and social messaging apps doesn't get affected that much, it is just annoying

S7 Edge dual SIM control

Hi Guys !
I have a Samsung S7 edge duos, for which i want to use two SIM cards - SIM 1 is my home SIM, and SIM 2 is a Global roaming SIM with data and Voice.
My question is whether its possible to set my phone in such a way that when I go on roaming i want my SIM 1 to deactivate data services and SIM 2 data services to kick in, since this a global SIM.
Is there an App for that or is there some kind of settings for the same.
Help in this regard would be highly appreciated.
Thanks
John

Not sure if you can do this, maybe with a task scheduler? Best choice is just to manually set your SIM2 to be the main SIM.

The only thing that might work is to call transfer sim 1 to sim two so that any calls received will ring on sim 2 which you can select as the active.
You can not cross connect the apns since they are linked to different sim cards.

Did you try all the dual sim manager apps? they say they do just that!!!

G935FD - Disable mobile data on second SIM

Hey Guys
Here is the deal..my G935FD is having connectivity issues (service unavailable) on the SIM card that provides backup mobile data but only when on 2G network. My assumption is that this carrier have move away from 2G and have limited connectivity capabilities in 2G. When switched to 4G, works just fine... however I want to use this carrier only for voice services and not data.
I already updated my modem to latest version with same results.
My goal is to disable data completely on this SIM, but the minimum setting on the Edge is 2G and on top of that is not possible to have both SIM running 3G/LTE. I also tried using a fake APN but no luck.
Do you know a way to accomplish this?

From what I could understand, you want mobile data on your primary SIM, and use the secondary SIM only for voice but the carrier is re-farming 2G and you can't have 3G on the 2nd SIM slot?
Well, there's no solution for it. One SIM Slot can do 2G/3G/LTE whereas the second one can only do 2G. No way around it.

Thanks for your help. So no way to only shut down data completely on the second SIM? Shutting down mobile data from settings shut it down for both SIMs, couldn't find a way to shut them now independently.

Under SIM card manager, when you see the Mobile Data tab, isn't it set to SIM 1? That would automatically disable Mobile Data on the 2nd SIM, however you can't get past the network mode restriction. So SIM 1 will be on 2G/3G/LTE, whereas SIM 2 will be on 2G only.

Very easy
Via the settings tab, get into mobile network tab, select access point names.
Choose the sim u want to deactivate and then select the APN and delete it with the menu option on top right hand corner.

using 3g doesn't mean it will use data.. when u chose the primary sim for data the other will never use data even on 3g.

Data with 2 sim ?

Hello,
i hesitate to take a second sim, but my interest is not to call but to have data.
Do you know if i can use data with sim 1 and sim 2 in same time, or the sim 2 is just to have another phone number and not specialize for data.
I have search, and it seems tha the sim 2 is not in LTE for the data but only GPRS/EDGE, that does not really interest me, does someone has test that ?
Thanks

4G Data works on both SIMS! The SIM where data is enabled will automatically switch to 4g/3g/2g and the other SIM will revert to 3G/2G. There is no restriction on where you wanna use 4G.
This is same with most of dual SIM phones as of now.

Thanks for the explication.

Are you sure about that? Because I need to buy for data also, and on G3 Dual SIM, 4G was only on SIM1, 2G on SIM2 always
