Hi! When I call from my mobile the call nearly always gets cut off at the hilariously specific time of 15 minutes and 32 seconds. My provider is 02 and my phone is a OnePlus 6. Other people with the same setup are having the same problem as reported in the following forum https://forums.oneplus.com/threads/phone-call-keeps-cutting-out-exactly-15-32.1080060/ It's not even that annoying but I'm just so curious why this happens!
