Volte option not showing in cellular network.
I have Asus zenphone max pro m1, I have 4g airtel sim, but in cellular network it does not show me the LTE option
When I asked the asus customer care they said "modal (ZB601KL) does not support Volte network. It support GSM/GPRS/EDGE,WCDMA/HSPA+/FDD+LTE and TD-LTE DSDV network bands."
But when i insert jio sim it does show me the LTE option.
I don't know what to do now.
