Frankly speaking, even if my phone support the YES VOLTE, I won't use it as my main call line.
As I check my YES connection at the places I going these past few days, the line only able to connect like 40% of the time.
If YES don't come out with piggyback on any telco soon, it just heading towards the death valley.
