Happy hours are every day during late night to early morning, during which time your package speed is doubled. Another thing to add here, watching/downloading of contents available on Dodear also consume you monthly data volume. Your dealer will tell you it is not the case and I also think it should not be counted by connect data counter but this is a fact. You can check it by getting logon to your user ID on connect site, note your current data consumption, then view/download something without doing anything else, then check your data consumption again, it will be increased accordingly.
