WISE introduced the unlimited night usage between 12 a.m. and 7 a.m. few years back, but it was crap until DSL was launched and many switched from WISE to DSL. I remember calling the WISE guys after midnight 3-4 times a week as I would have no connection at all. (I would need it to work sometimes, not just download stuff).
Anyway, I didn’t expect a better outcome from DSL and I wasn’t wrong to think so. In fact, I tried downloading a movie on a DSL connection yesterday night and woke up to find it stuck at 5%. I downloaded it again during the day and it took approximately 4 hours for a 600Mbytes movie.
