Lose data when on call.

[Khatera]

I've had the galaxy s8 for over a year and a half now. Got it from Verizon and then switched networks a month after getting it to tmobile. I am suddenly loosing data connection when I'm on a call. I haven't had this issue before. Advanced calling is on and always has been. Any ideas?

Also I want to add that I Never got video calling to work on this phone (except through third party apps like whatsapp). I don't care to fix that problem but added it because it is related to advanced calling feature.

When you say you have advanced calling on, can I assume that means your calls are going over Volte? Do you drop calls or just lose data connections in apps? When the call ends, does data return?

There is no "Votle" option in the advanced calling phone setting. I have two options under "advanced calling" setting that say, "activated advanced calling (service upgrade to HD voice and video calling)" and "advanced calling (turn on/off HD voice and video calling". The first one that says activated is greyed out and isn't clickable. The second option is. When I click on it, I have the option of HD voice only or HD voice and video. I have it set to "on" and selected HD voice and video. This has always been the case.

My data immediately comes back as soon as the call ends. My calls go out over the mobile network. I have changed the mobile network selection to see if that changes things, but it didn't. I am just on the t-mobile network. Network mode: LTE/GSM/UMTS and network operator: T-mobile. Nothing about Volte is under mobile network either. The calls are not dropped, and my signal is really good. Just normal phone call and then data suddenly disappears. Hang up, data comes back. Never happened before until last night.

Okay. If it just started happening without you making any changes or applying any updates, then it's probably a carrier-side issue. You might call T-Mobile or you could wait a few days and see if it clears itself up.
