Well the app works pretty good on my mi max and my sim is in sim 2 while sd card is in sim 1 tray . UI is pretty standard and simple have to keep in mind all the different types of users when designing it and maybe it is working fine for me coz I ' m on WiFi right now ? Edit 1 haven ' t sent money yet but have set mpin and viewed balance statement easilyEdit 2 have sent money . And also made collect requests . Working flawlessly and super fast and looks easy to raise disputes also . also looks like they still haven ' t started charging for each transaction yet <| sep |> Cost for Porsche to develop their exhaust system to maximum effect ? Very very not cheap . Oh yeah , of course , but that cost is not being paid per each slightly defective part , so apparently most of that price is Porche tax then ?
