The main difference between a 'Booster' and 'PAYG' is that there will be no restrictions on your services with a 'Booster'. A 'Booster' should be used when:

  1. You have used all of the data in your plan and don't want to be on our free 200MB restricted speed service.
  2. You have used all your local or international minutes but are still expecting to make a lot of calls. In this particular case, a 'Booster' will be cheaper than 'PAYG'.
For local and international minutes, use 'PAYG' if you only expect to make a few calls before your plan renews.
