Unqualified personel who is un able to help

I have tried to contact Vodacom in connection with my security camera system - to be able to connect to this system at my home via internet WI-fi Vadacom from distant places - ie not at my house. The company that installed my security cameras advised me to UN RESTRICT the SIM card specified for my Wi Fi. I was refered to the Vodacom store which knew nothing about 'Un-restricting' a Sim card. The contacted Vodacom at 082156 and asked me to request an \APN form to be sent to me
