Is volte working in Airtel India ?. My phone drops to 3g or H from LTE when making call. I am on 3.2.2.
The earphone center button when pressed will launch play music on my old phone (Nexus 5). Unfortunately this is not happening in Oneplus 3. I have to manually launch play music once i plugin the ear phone.
VoLTE not yet deployed by Airtel India. You could try Relince Jio once it is launched. Supports VoLTE.
Any idea on the earphone issue ?

I have HTC 816 Dual SIM indian Variant and i have flashed the CM12 Dated :2015-04-26 11:35:05
I am having 2 specific problems and they are :
1. Audio from the speakers are cracking when a song is being played on full or 90% volume..
2. Whenever i put one sim on 2g and one sim on 3g, calls are possible from the 3g sim only. From the 2g sim if i try to call or receive a call neither the speaker works nor the Mic. Even if i reverse the 3g/2g mode the 2g doesnt seem to work.
If you have a solution please help me out! Thank you..

I have a EU (Norwegian) version of Z2 Play (XT1710-09) running Android 8. When I use a Norwegian SIM "Enhanced 4G LTE Mode" is displayed but as soon as I use JIO sim the "Enhanced 4G LTE Mode" option is not shown. The same thing also happens for Samsung Galaxy S7. The same JIO SIM works fine with IPhone 8 Plus.
Any idea this behavior with JIO SIM? Will it get solved if I flash a Indian ROM?
Hi there :
I use dual sims on my 7T. from different carriers.
SIM1 only for voice call and on 3G network (in my place 3G has better signal than 4G)
SIM2 for DATA and on 4G .
when i do voice call by using SIM1, Sim2 drop to 3G and slow speed.(showing H or H+ on top bar. )
as in Australia non-carrier support VOLTE or VOWIFI on Oneplus 7T (or say all the oneplus phone base on my research),I can understand when voice call the network have to switch to 3G from 4G then go back after calls.
but in Dual Sim setup ,is it should be remain the network type and has same fast speed ?
Thanks in advance.
There's only one modem, so it can only do DSDS (dual sim, dual standby). When in a call, the other connection is dropped. This is why your data switches to sim1's 3G.
Are you intentionally trying to avoid using volte/vowifi for calls? If not, you likely need to do this: https://forum.xda-developers.com/oneplus-7t/how-to/volte-op7t-t4007085

Hi Thanks for your reply.
I see the reason. so DSDS can not support the way I want to use.
I tried the link you mentioned before. no luck.
In Australia, oneplus is not officially on market. So none of carrier support Volte on Oneplus.
My understanding is VoLTE and VOWIFI have to be supported by Carrier AND the Phone.
My oneplus 7T can open and use VOLTE when traveling overseas if I use local sim.
Our local forum have discuss this issue long time. No solution so far.
Some other phone like xiaomi or so can be supported in Australia. I was wonder why oneplus not.
Flash other country's rom may be ? Is there have a Volte international roaming thing ? So 7T can be pretended a Euro device roaming to Australia and using Volte ?

We really need to get through to Asus that we need an update to enable VoLTE on TMobile USA soon or our phones are useless.
Some people might have a critical need to make a call and they'll find they can't!
Yes even WiFi calling features is missing.
Used 2 Sim Cards (SIM 1 & SIM 2)
Settings , then Network & Internet , then SIM Card at the bottom " Use mobile data for VoLTE Calls via..." turn it on . My calls have been working fine .

Tried this. Not getting VoLTE calls on TMobile USA. It still goes down to 3G to make the call. Not January yet so yes calls are currently working on 3G. But this seems as if it will end comes January. I hope ASUS can bring us an update soon so VoLTE will work on TMobile USA.
Hello, I bought an S7A on eBay. I unlocked it with the GSM unlock code provided. Everything works fine, except ... I can't make or receive calls. When I make a call, no ringing tone, and it hangs up 20 seconds later. When someone calls me, the same, then they come across my answering machine.
I'm on the latest version of Oero available, no root or whatever. From what I saw (on GSMArena), the phone uses compatible frequencies in France.
I am at carrier Bouygues Teelcom.
You have any ideas ? Thank you !
PS: I translate from French, please be indulgent!
Same problem, this phone does not work in China
Since then I have understood the real problem: the phone cannot switch from the 4G network to the 2G network for calls on its own.
I don't know how I did it, but now I can make calls without any problem, but switching to 2G is very long (15 s).
I specify that it is impossible to use VoLTE to circumvent this problem.
For receiving calls, the phone does not switch to 2G and the incoming call still fails.
But I can force the 2G network (With the Samsung Band Selection app). And there, incoming calls work, but we only have 2G to surf.
When connected to WIFI, the phone automatically forces the mobile network to 2G, so incoming calls work without the application mentioned before.
