I'm experiencing issues with VOLTE on T-Mobile. My phone switches immediately from an LTE+ DATA connection to HSPA the moment a call is placed. Of course, VOLTE is enabled on the settings side. I'm running an unmodified system, upgraded to PIE.
I've been on the phone with T-Mo to make sure the APN is correct (nothing special to mention here). I've also tried different connection combinations using the *#*#4636#*#* with different results but, even though the phone connects really fast to DATA (LTE+), I cannot get VOLTE to function in any case. On the other hand, WiFi calling works just fine.
On a chat with Razer, they just told me that VOLTE is unstable with T-Mobile and, to disable the function altogether from settings.
Before I give up, I'm asking the geniuses here for ideas or experiences? Any ideas anyone?
