A TopUp plan can be recharged with airtime and a contract is open-ended and has a spend limit. You can buy bundles until the spend limit is reached.
A spend limit is defined as the maximum amount that a subscriber wishes to spend per month. This amount is set by you or Telkom. How does a spend limit work? You can select a spend limit up to which you may want to spend, but not exceed. Once you have reached the set spend limit, your account will be soft-suspended, and you will only be able to receive calls. The suspension can be lifted and a temporary increase in spend limit set by dialling the Call Centre on 081 180. You can also request a permanent spend.
