It was that VoLTE wasn’t supported for that particular model of phone. VoLTE is very much the norm here although I’m unsure if every phone uses it now. My flip phone probably doesn’t, but it’s hard to tell with how stripped down its manufacturer-customized Android is.
I use it in my 50cc motor scooter since it’s got a barely 1 gallon tank that lasts me ~2 weeks a fill, so the price difference is negligible
I figured the higher octane would make a noticeable difference since it’s such a small engine
But reading this thread I’m now thinking maybe I shouldn’t do this?
