Dual sim not working at a time - Galaxy Note5 Q&A, Help & Troubleshooting

I have purchase the Note 5 Dual SIM. Both SIM's are active, one in 4G and the other in 2G.
I want to use data from the 4G sim (emails, browsing +Phone and text) and that the 2 G SIM should support Phone and text only.
My issue is that I am able to receive calls and text sent to either SIM, but if I try to make a call or send a text I am only able to do it from the 4G SIM. If I try to go it from the 2G SIM I get the following error "Mobile network not available".
It is not an issue with the SIM card as I can switch them back and forth and both work fine in the 4G slot.
Call forwarding is not allowed by my 2G sim network provider.
I can only make call if i convert it from 2G to 4G.

[Q] dual SIM question

Quick question for you dual SIM users.
Does the Moto G2 support 3G on both Sims?
I intend using two three SIM cards, but they only support 3G. So if SIM two is only working on 2G it would be no good to me.
Thanks
The data connection is for one sim only, you get to choose if you use data on sim one or two, data is automatically change sim, for example from 3g sim1/2g sim2 to 2g sim1/3g sim2
Thanks, I'm with you. So with my two three Sims there would be only one SIM on at any one time.
I have I signal SIM moto g1 now, and if I switch to 2g only the three SIM no longer works.

Both Sim work at the same time while I'm using 3g in any Sim.
Data is available only for one Sim at a time, but the change is really fast and automatic when you select which Sim to use for data
I use mine with same carrier, it uses the 850mhz band.
Remember this phone is dualsim standby, it means if you're using voice in one Sim the other is unreachable.

Yes just on most networks if you are on 2G the sim still works. On three they don't.
A three SIM won't work on 2G no calls text or anything.
So even with both sims in standby only one would receive calls, am I right?
Only way to receive calls on either SIM (from standby) on a moto g is if at least one SIM works on 2G?

I've own two dual sim phones s4mini (lost it) an this moto g 2014, both are stated as dual sim standby, I haven't notice any difference in the way they handle simcards/data/voice.
On both phones I've use same carrier/numbers, one is personal (same number for 10+ years) the other from work (same number for 5+ years).
I've never missed a call on either Sim.
Even if I'm downloading something I can receive calls and text messages on that sim the download stops but my phone core functionality is still a phone for both simcards with any combination of data in 2g/3g or 2g/2g.
I'm never going to carry two separated phones, for me is enough the dualisim standby functionality.
For you is a pain that your carrier don't support 2g network any dual sim standby won't work, you need a dual sim phone with two separate modems

Thanks for confirming that, only other thing I can do is use one SIM and activate call divert on the other number.
That's the main drawback with three only supporting 3G/4G

Data Connection Switching Leaves One Sim With No Service

The problem im facing with my Xiaomi Mi5 is that whenever i switch the data connection from Sim 1(Jio 4G) to Sim 2(Airtel), sim 1 loses the signal and remains unavailable for calls both incoming and outgoing. I tried to change the preferred network type and swapped the sim slots but nothing seems to work. If you guys can help plz do so.
Note: Sim 1(Jio 4G) is 4G only network it doesn't work on GSM or WCDMA.
the non-data line only does 3g, or 2g if 3g isn't available..

I'm also facing the exact same problem!!
But I think it is operator-specific because Jio 4G does not support 2G/3G networks but only 4G LTE. However, Airtel 4G on the other hand switches to 2G/3G networks when not using data services.

Thats what I thought until I checked it on Asus Zenphone 2 it works perfectly fine with other sim on 3G and Jio on 4G.
When I'm using data on 4G on Mi5, the other sim gets 3G network but fluctuates very much and if you change it to 2G only, it will automatically get back to 3G network.

Dual Sim Issue

So I have my Verizon sim in tray 1 & my T-Mobile sim in tray 2. What I am trying to do is have the data push through the T-Mobile sim but still maintain calls and text coming in from Verizon sim. When I set Dial to sim 1 & Internet to sim 2 in the options it just shuts down the Verizon sim completely. What am I missing? Is what am trying to do not possible?
20 views and nada, come on someone has to have some input they can provide me lol
So I finally got the phone to keep both sims registered to their networks and my calls and sms work with it set to my Verizon sim but I can't get the data to push through on the T-Mobile sim!!!!! AHHHHHH
I think the Mi MIx only has 1 4G radio? So that if both SIM cards require 4G connection, only 1 can be connected at one time
I understand, this is exactly why I wanted this phone too! Where did you buy yours and how long till you received it?
No voice calls.

Thank you.
Has any one resolved this issue?
I recently got a VZW SIM card, and everything works when it's the only SIM in the Mi MIX...but if I also put in my Project Fi SIM...I cannot send SMS via my Project Fi SIM--which carriers my main number...even though MMS also works on my Verizon SIM card......

Dual Sim Data Questions

Hi,
Got the note 9 since friday. working great. but i noticed that when i call on sim2, i can use mobile data of sim 1.
Default mobile data is from sim1. and phone calls are set to ask every time.
now my sim2 is my work number. during the working hours i call alot with this number.
my sim 1 is my private sub from t-mobile. and i mainly use the data plan of it. since i dont wanna use the internet that my boss pay's for for my personal use.
Now since i got this setup. what happends is. some one texts me a foto through whatsapp. and then calls me to sim2 before i can look / dowload the picture. then when i pickup the phone they ask me did u see the picture i sent you. i then open whatsapp. but i get the msg no network.
what i noticed is that when i call on sim1 i still have LTE data. (cause sim1 provides the data)
so it cant use data from sim 1 and voice from sim2 at the same time?
also is there a way to set certain apps to use data of a specific sim card?
lets say i open my 2nd whatsapp that it loads the images sent there from my sim2 network
but when i open my 1st whatsapp (2nd app cloning) it uses data from sim1?
or any other apps for exmp chrome and samsung internet?
is there any tweak that automates the switch data to sim2 as soon as i make a call with sim2?
now i can just click on the sim settings menu and change the default data to sim2 to receive data during the call. but when im driving in my car this are alot of buttons to press and i rather not.
i don't own N9 yet. read about dual sim technology varieties on the net, theoretically N9 should be able to get dual VOLTE feature on both SIMs (assuming it supported by carrier(s), and phone shows VOLTE icon on both SIMs). in the event you are making call on SIM 1 & trying to get data on SIM 2 or vice versa, this requires dual sims dual volte (DSDV) feature kicks in and liberates you to choose which SIM to get data from.
might really want to consult with your carrier(s) if both SIM support VOLTE.
Are you able to get VoLTE and WiFi calling to work on the international dual sim F variant of Note-9 on US T-mobile network?

In Settings / Wireless & Networks / Dual SIM, see that only one SIM (you can choose which) can be 3G/4G
Hence one SIM will be on 3G or 4G, second SIM must be on 2G - but if your operator for that second SIM does not provide 2G you will not be able to use that SIM
In Settings / Wireless & Networks you can disable 4G and in Preferred Network type you can force GSM (2G) only - that way you can test which of the two SIM cards / operators provide/have 2G signal

In Dual SIM Settings you choose one which is 4G, the other will be 2G/3G
Cannot help you more, I have both SIMs 2G/3G/4G, hence no matter how I set, both work
Try playing yourself, test both SIMs one by one only, in one and the other slot, with various settings (4G enabled/disabled, Pref net 4G, 3G, 2G only)
Maybe you have problem with one of the SIM cards or one slot
