https://www.airtel.in/volte/ to check VOLTE Compatible Handsets.
Airtel : We would like to inform you that, your handset (Asus I001DE) is not enrolled for VOLTE service.
Firmware version of ASUS ROG Phone II (ZS660KL) is WW-16.0631.1910.44_0
This Topic has been discussed before and VoLTE has not been enabled in many countries and not just India.
There is a trick to get it working
Can you share how to do it please ?
Put your sim in one of the supported handsets from airtel.in/volte then call customer care about volte not available once you see volte in the supported device remove it from that device and put that in your device .
You will see volte
@bgsetty See this method
The problem is...once I put my sim into a supported device...I will already see Volte. I am not from India but from Singapore and we have had Volte for quite a long time now...so yea...
Can you share how to do it please ? My Mobile only 4G Right hand top corner
Share the same experience with Jetjosh. In Croatia we have VoLTE for several years now. My son's Samsung A3 from 2017 supports it immediately. Other 3 Samsung phones in the family support it.
Tried with Samsung A8
Yes , now working . Thanks for your suggestion
