If you are non-unlimited Speedy users (personal, time-based, and professional), this will be a good news for you. Speedy gave unlimited access without reducing your quota or your time slots starting 8 PM until 8 AM. It will be totally free usage. Too bad, this good news won't be implemented in all cities in Indonesia. Only in Cilegon, Serang, Jakarta, Bogor, Tangerang, Bekasi, Depok, Karawang, Bogor and Purwakarta.
Please check the rules here, as it is kinda tricky as you will have to login after 8 PM or you will be charged as normal rate. Also you must not be logged in more than 12 hours or you will be charged with normal rate again.
