I didn't get any daily survey yet. I am a member since 6th april 2015 and now I am a premium menber. All the time i click the Survey butten it says "Sorry, there are no survey routers available for your country at this time." i am from sri Lanka. is that the reason for that?

Yes.

Thanks Valerie

I wouldn't say it is the total reason but I would say it is the main reason.

Other factors may play a role in denial with some survey opportunities but if you're
not getting them at all, I'd say your location is the main reason.
