Sim Card for Telkom

Hi there guys,

I wonder if you can assist please? Is it at all possible to receive from Telkom (If anybody would know), a sim card to use in a router if I have uncapped ADSL at home? This sim card would be linked to my uncapped line, so I don't pay two subscriptions.

I travel a lot and don't really make use of my home ADSL.

Any help would be appreciated

Thanks
