For Blackberry passport
I'm using blackberry passport. When I tap m.checkvist.com into url bar in my native browser, I only get white blank diplay without any text, menu. I tried other browsers for android such as opera, dolphine, etc. but ended in the same results. Could you correct it?
I'm sorry, we don't have such a device :( Possibly, the fix requires a true android app.
Or you can try using Google Chrome, if it is available for your device.
