Here I wish to Share an Idea... Which helps you to Activate VoLTE on Samsung Phones.
This Method I Have Used in many Phones.
Some Samsung Phone Variants Has This VoLTE Function, But Phone Actually Won't Connect to VoLTE.
Mostly After a Software Upgrade or Reset.
For Them, This Steps will help.
Follow This Steps to Activate / Enable VoLTE in Samsung 4G Phones
- Dial *#272* 15 Digit IMEI # ( *#272*000000000000000# – Replace ” 0 ” With Your IMEI )
- Select INS and Tap Install
- Phone Will Restart Automatically
- VoLTE Will Work After The Successful Reboot
