Volte problem in mido with stock rom - Xiaomi Redmi Note 4 Questions & Answers

I'm using 2 sim cards. 1st sim is jio 4g and 2nd is bsnl. When i switch data to 2nd sim bsnl, the network in 1st sim jio goes off and it shows no service. Please help how to resolve this issue, should i try switching the sim cards in both the slots???

You can have lte only on one sim slot at a time. So, if jio is lte only service and you switch to 2nd sim for data, 1st sim (jio) will loose signal, because lte is on 2nd sim.

Lg v10 h962 dual sim not standby

Hello my everybody, Happy July 4th to you all.
Please does any V10 H962 owner experience this same issue?
Please do you have an idea of what might be wrong with my phone. My dual sim is no long standby. Sim 1 usually get 4G LTE and Sim 2 Gets 3G and 2G voice. Now I can only use either Sim 1 or Sim 2 at once. When One sim on 4G LTE, the second sim will Not get signal/coverage until I switch back to other one. Pls what can I do? I have migrated from MM to Lollipop, still the same issue.
Please any help will appreciated.
In which country are you living?
Most of the mobile carriers are switching off 2g networks. So make sure they are not doing so in your country.
The Lg V10 dual sim puts one sim on 4g and the other on 2g, since the 2g Network is shut off the phone has not signal on the second sim card.
I think it's time to get a new phone that supports 4g on both sims or 4g/3g

Help needed for LTE Bands

Dear Users,
To increase the jio simcard speed for internet i changed my LTE band to "Band 40" by following this link (https://www.youtube.com/watch?v=0mRP3N3lLTo).

I have changed the band value to default but still my sim card is not detecting.
Can anyone help me please? @war_machine, @Umang96, @GuneetAtwal

Dual SIM card CM13 vs LOS14

Hi,
I've got a question about using 2 SIM cards.
With the Redmi Note 3 Pro (Kenzo) I have read it was possible to use 2 SIM card but one would be connected to 3G/LTE while the 2nd card would only be connected to 2G. It's not possible to connect both of them on 3G/LTE at the same time. That's exactly what I experienced in the past and I was fine with it.
Right now in my phone I have 2 SIM cards :
SIM1 : Bell Canada (Voice + Data LTE) provided by work. Bell shut down their 2G network a while ago.
SIM2 : Fido (Data LTE only) for personnal use. Fido, owned by Rogers, still has Edge / 2G network.
When I was still on CM13, if I selected my Fido SIM card for my the data connection, I would instantly loose the signal on the Bell SIM card because Bell has no 2G network anymore. It was fine for me that way, it meant I wouldn't receive work related call while I'm not at work (we have a dedicated after hours service and I'm not part of it...) If I selected my Bell SIM card for data, my Fido SIM card would stay connected because Fido/Rogers still have a 2G network.
Today I installed Lineage OS 14.1. Something unexpected happens, if I enable my Fido SIM card, I can see the LTE icon for the Fido SIM but I also keep the connection to the Bell network.
Was the fact that both SIM card couldn't connect to 3G/LTE at the same time a limitation that was lifted in Lineage OS 14.1 ?
Thanks

Dual 4G setting

Hello, I have a question about the dual 4G setting before buying this phone.
I know it's a dual 4G standby, but can you confirm that system auto switch network on secondary sim when receiving or sending MMS ? Is it fast ? Does 2nd sim use 4G in this case ? Does system auto come back to 1st sim after ?
Actually my 2016 dual sim phone can only use 4g for 1 sim, so when I receive mms on sim 2, network is only 2G/edge
so I confirm that dual 4g option allow 4g mms on the two sim cards
