The layout is designed for ergonomics so you can find the sign in MCW, member area right at the top right corner. You can visit the website to find the latest version where the login button is very easy to tap. Once you click it, just enter your registered phone number and password to get full access. After you are logged in, the replenish balance button will appear in your account dashboard. The Nagad option is usually in the first row of payment methods because it is so popular here. I find the mobile interface much easier to navigate than the old desktop version. Everything is just a few taps away and the icons are very clear. If you have any trouble, there is a live chat icon at the bottom of the screen.
