as per website they have mentioned abt plan 849NU only. but then again i dont know if their programs wud be capable of different NU timings for different NU plans.best way to know is download 2MB data at around 10:30PM and then disconnect and on next day check if its accounted. i say next day because sometimes logs appear the next day. so to be safe, for 1 day dont schedule download betn 10PM-12AM, just run the test and verify first.
