ICASA will be soon passing new legislation regarding expiring time of data bundles. So far MTN and CellC is discontinuing certain denominations. We do not yet know what the new denominations will be.
MTN has discontinued 5MB, 500MB, 2GB, 5GB. The rest of the denominations SHOULD BE WORKING NOW - it seems they resolved the problem that appeared since Friday 18 May.
CellC has discontinued all their data denominations (we removed them from our sister site https://myairtime.co.za/ already).
We apologize for the inconvenience.
