Most times if you may be an all night worker and using the MTN night plan would be a great advantage to you as it would be quite cheaper and equally quite faster since the number of users browsing at night are usually lesser because lots of them are asleep

If you are using other network, you can check the airtel night plan here as they probably have a better and cheaper plan for night plans

Unfortunately, for the MTN night plan, there are no known night plan for MTN to the best of our knowledge

If you must use a night plan, you can consider switching to glo data plan or Airtel plan or 9mobile plan
