Tokolozi , Dec 3, 2020 : Is it a voLTE call? That would be then because the modem is busy with the call on 4G
Arjun_Choudhry , Dec 3, 2020 : Kindly elaborate here. Do you have 2 sims? Also, you're referring to mobile data here, right? Also, the issue occurs when you're on a call on one sim, and have the data card set to the other sim, right?
Shailender Sharma , Dec 3, 2020 : Enable VoLTE Settings - Wi-Fi and network - SIM and Network - SIM 1 - Enhanced Communications - Enable VoLTE
Arjun_Choudhry , Dec 3, 2020 : Does your sim show Volte at the top in the status bar? Volte isn't available for a lot of locations for VI in India
Vikhyath_Kowalli_ , via OnePlus 7 Mirror Gray , Dec 4, 2020 : My data gets disconnected too while on call even though volte is enabled and is displayed. Even I'm on Vodafone network.. so maybe it's the service provider..
Arjun_Choudhry , Dec 5, 2020 : That's because Volte is not available at your location, if you have enabled it in settings. Don't worry, VI is expanding their Volte network, so you should see it soon.
Iamhasannaqvi , via OnePlus 7 , Dec 6, 2020 : You'll need volte to be able to use internet during the call.
