We only support DSL Self-Install, meaning Telkom connects your existing phoneline to the DSL system, but you setup your modem at home yourself. Which is why we only bill you for the DSL line management and not the installation fee. You will only be billed once the line is active on our end. The DSL line activation is dependent on the area work load.
Unfortunately you can't switch ADSL to Mobile data. You would need to sign up a different package for Mobile data. Firstly you would need to check your area for the coverage that you can get. This helps so you know the type of speeds you can expect on Mobile data. We also do not offer Uncapped on Mobile which is what you indicate you have signed up for. The biggest package you can get on Mobile data is the 20Gb for only R987 PM (Incl. VAT) and with an extra R99 PM you can get double the data you have signed up for.
