When I check my internet speed on mobile it shows no flash player. What to do?

When I check the internet speed statistics through speedtest.net it shows properly on the laptop. But when I do the same thing for my mobile phone it doesn't work well. In fact, it doesn't work at all. My mobile phone is capable of running flash games and access other sites like Neeraj Kulkarni blog and Yahoo which do require flash player to run properly. What is the reason? Please help.
