[Xperia Z4/Z3+ General] HBK_Rishav:
VolTe Port for E6553 and E6533(Both single and dual sim versions)​

Here we will understand that how to use volte with our beloved E6553 and E6533.
​

How it will work?

ANS:

Actually Xperia Z3+/Z4 and Xperia Z5 both have the same chipset where Xperia Z5 has official Volte support but Xperia Z3+/Z4 does not. It's clear that Xperia Z3+/Z4 have hardware support for volte and we just have to do some software level tweaks to make it work!​

Does it supports all network's volte?

ANS:

Possibly no! In my region, only one telecom provider supports volte i.e. Jio and it's working flawlessly without any issue. ​

NOTE:​

You should have your bootloader unlocked!
