It's getting harder and harder to find providers who work with MOL and most want you to use their app with just UN/PW.
It's actually pretty easy to find out what the Portal is so you can use MOL. Most providers just use a rebranded Smarters app so download their app and install MX player to your device and go to player settings in the smarters app and change to external player using MX player. From there select a channel to view and long press the OK button, at the top of the page you should see 3 dots for menu, select properties and it will show you the url/Portal info. You just need the first part and the port not the whole thing. Write it down and then you can log into MOL and add the portal, username and password.
