so i just got a new airtel sim . After activation their was no option of volte for the sim and volte wasnt showing in notification tray. After some days i used this airtel sim in another zenfone max pro and it was showing volte and then i swapped another airtel sim into my phone and volte was working.
But then i inserted my airtel sim again and volte option wasnt present in settings option neither it was showing volte.
