From last few months Jio 4G is making rounds of news and it was available only to limited - partnered brands like samsung / Lyf, etc.
and those who were able to grab the sim cards were having difficult time using it with Meizu phones as they were not able to call/sms using VOLTE (HD Voice in flyme).
So I have come up with a temporary solution to fix the situation and enable the HD voice in Meizu m3 note. (This may work in M2 also - if it has HD voice option in settings , but I have not tested it personally as I do not have that device now )
Steps to use VOLTE in Meizu M3 note :
Part 1 :
Name : ims
APN : ims
APN type : ims
APN protocol : ipv4 / ipv6
Do not touch the other fields. - > Save
Now, your APNs should look like this :
Part 2 : This is a little complex part for normal users as this involves engineering mode edits.
"Proceed with caution"
select IMS and click START button.
It should look like this after starting :
4. Now come back two times and swype right to see Telephony menu in engineering mode.
5. Again come to common menu (inside IMS menu)
6. Come back twice (to IMS menu)
DONE .. Now click home button, exit engineering mode and check for HD voice symbol. If you see that , try calling any number from the default dialer - Fast method is to call the customer care number 199 to check if the calls are getting connected or not.
Now everything is setup.
If your phone is not showing HDvoice symbol beside the battery icon even if the HD voice is turned ON in settings (it will be next to data sim selection), try to turn off the sim and start it back (Just go to airplane mode and come back), check.
Any questions are welcome.

Finally to solve the jio to jio issue - use this setting (as someone tested and commented in this thread.. )
Engineering mode --> IMS --> set VOLTE setting in this page to CMW500 .

You can skip that step. May be that settings is some where inside in your firmware..
But Ussd is just to check your balance and for other stuffs like in idea / airtel you do *121* , etc.
So If you are not getting that settings, ignore ussd and jump to the next steps
Its only in india? What about ither country?
Ussd suprrot And rcl not found
