Mobile Data not working during calls

[AnkitSahu]

Ive been using the S25 since its launch. Since day 1, there is this issue that Ive been facing. When Im on a call, my mobile data stops working. I default sim for calls/text is sim1, and for data it is sim2. But switching to either sims doesnt help. 

I have tweaked all possible settings, but to no avail. Even updating to the latest sw updates doesnt do any good. 

My friend who has the same phone doesnt face this issue.

I have not yet tried factory reset(would want to avoid that hassle).

You need to enable data switching and back up calling option and your sim should have volte enable

All of the aboves enabled. Still.

Jio+Airtel

Activate VoLTE, which allows voice calls to be carried over the 4G LTE network. If VoLTE isn't enabled, your phone might switch to an older 2G or 3G network for calls, which often don't support simultaneous data.if not Reset network settings.

I have 5G enabled for mobile data. Even downgraded to LTE, but didnt work.
