Help regarding Volte - Xiaomi Redmi 3s Questions & Answers

I used custom ROMS as well as stock MIUI but there's a problem with my phone
I can't use Jio Volte in slot 2 due to which only mobile data works while the calls and SMS don't work either outgoing or incoming and I can't use Jio4gVoice (JioCalls now) because it requires internet which I cant keep ON all the times
Any way through which I can access Volte in slot 2?? I am unable to use slot 1 because it requires micro SIM but I have a nano one and can't buy a nano to micro converting template cause the markets are closed (Due to corona)
Plese help me guys!

please help me out
sorry for my english!
Jio is not fully supported on this phone, partly due to missing VoLTE support in firmware and partly because of how Jio doesn't support GSM/2G which is the standby mode for the secondary SIM as the phone doesn't support dual 4G mode. In other words, if first SIM is in 4G mode, second is forced to 2G, and this of course causes problems for Jio SIM.

Voice Break during call

Hi All,
I am from India. I have 2 sim cards from service providers Airtel and Jio. when i make/receive a call through Jio, the other person can hear clearly. But when i make/receive a call through Airtel, the oher person can hear my breaking voice. for example if i say: "Hi, How are you?" they will only hear "H_ __w __r_ y"
while testing with a continuous voice, i found that the breaks in between have exactly same gap time (approx 1 sec).
Also, this only happens only in 3g/4g mode. if i put the airtel network in 2g mode, there is no voice break.
I also got the sim card changed, but it is the same in new sim card as well.
I tried swapping the sim slots, it is the same in both the slots.
I tried putting the sim in other phone, and it works fine.
the question is, if my phone has problem, how does Jio work fine on both the slots? and if there is problem with Airtel network/sim card, how does it work well in other phone or in the same phone with 2 mode?
I am really confused, and tried searching for a solution on the web. I tried switching off Noise cancellation, switching off "OK google" as well.
Some help / guidance would be really appreciated...
Note: Jio is VOLTE based network and Airtel is normal 4G
Hello,
am having the exact same problem. Jio on Volte and Idea on normal 2g (i suppose because there is only one common setting fro both sims i.e 2G/3G/4G Automatic). Jio works fine but idea call breaks on every call i receive and the calls i make. Any solution ?
Its related with h+ you wont have any issues with 2 g or 4g that h+ issue is killing me
Hey I am facing the same issue. Your problem solved by some one .. or still facing the same yet.

There could be 3 possible ways.
1) Software bug
2) sim slot pin breakage
3) sim card chip problem
Identify the root cause at first.

2nd and 3rd not possible. Since data and messages are working.
Can you provide more information.
Are you on 4g network.
What type of error do you get.
Your circle.
Have you changed your network settings using *#*#4636#*#*?
Have you tried calling using 3g and 2g only?
If not choose WCDMA only (use above code). Also try with GSM only.

Same problem here. Solution for now is to change to 2G network, at least for me. When I try to call with 4G preferred sometimes it work, but when it works they can't hear me and I have to scream. This Pie update have so many bugs it is ridiculous. I can't believe they put such ****ty update to the masses it seems like BETA version. In Oreo when making call phone switches from 4G to 3G instantly now in Pie switches worry slow if it even switch and the signal is so bad that the call drops and that is in places where the signal is perfect
Hi, since last 4 days i am facing same ptoblem cellular SIM in slot 1 not working for incoming and outgoing calls and outgoing sms but internet and sms service (invoming) is working perfect on 4G

But when i inserted this same sim in slot 2 all things work perfect. same problem occurred even when i inserted other network sim in slot 1 (internet and sms(incoming) worked but unable to do calls) I had factory reset but problem not solved
I am using poco x3 nfc
I anyone have solution plz tell me

Simultaneous 4G support on both sims?

Does this phone support 4G on both sims simultaneously like HONOR 10?
Yes, it supports simultaneous dual VoLTE.
Does this mean, if i have a volte enabled sim(jio) in sim slot 2, and non-volte sim(airtel) in sim slot 1, and i have data enabled on sim slot 1(airtel), then the sim in sim slot 2 DOES NOT go out of service, and i CAN make calls from it..
The reason i ask this is because, in other smartphones like Mi A1/RN3 , when i have the same above scenario,
the sim in sim slot 2 DOES go out of service, and i CAN'T EVEN make calls from it.

This phone support TRUE Dual Volte unlike other phones. So yes you can set data inn Airtel and use Jio in second sim simultaneously. You can even use Dual Jio SIM in this phone.

Sir, I am using the Zenfone Max Pro M1, the dual VOLTE is not working, when I am using one SIM for the call the other SIM is going offline, in other words when I am on phone call the Mobile data connection is getting disconnected on the other SIM. Does anyone experiencing the similar issue?

Facing same issue, Asked customer support executive for the same and according to them this is bug and we need to go asus service and ask them to resolve this.
Scenario: Airtel/Cellone on SIM1 and Jio on SIM2
1) Data is set to SIM1 and Jio calling works fine. However, data is 2.5G/3G (SIM Card limitation) hence not sure about dual VOLTE 4G.
2) Data is set to SIM2 (Jio) and working fine. However, as soon as I receive a call on SIM1, mobile internet connectivity is disrupted and I cannot use mobile data while on call. Note that the mobile data itself does not show disconnected (the x mark). The only way to use data during call is wifi.
3) Data is set to SIM2 (Jio) and works fine during call if the call is received on SIM2.
I've had no issues with jio and Vodafone dual volte.
Airtel has no LTE coverage in my zone

I read this on asus website .So , we cant say that it is dual 4g volte.
" Both SIM card slots support 4G LTE network band. But only one SIM card can connect to 4G LTE service at a time."

Hmm, it is dual 4G Volte but not dual ACTIVE 4G Volte.

VoLTE not working

Is there any hardware issue which may lead to inactivity of VoLTE on sim slot 2 and inactivity of mobile data on sim slot 1? Mobile data and VoLTE won't work on sim slot 1 and when I switch to sim slot 2 VoLTE won't work. I have tried using a different sim card in my phone to get the same results. Whereas the previous sim is working fine in another phone. Please look into it.
