The $29.95 SIM Pack is for mobile phones & the $30 Broadband SIM is for laptops and/or desktop computers. Some newer laptops/notebooks come with a built in space for a SIM card to give the customer internet access, this removes the need of a customer buying a broadband dongle. Customers simply put the SIM directly into the machine and away they go. Note: not all laptops/computers have this capability and customers should check first before buying the broadband SIM Card. Also note: these are not interchangeable, meaning you can’t use the normal $29.95 SIM in a laptop or a $30 Broadband SIM in a mobile phone.
