eSIM using Mobile Data

Telstra, Optus, and Vodafone all allow you to use an eSIM instead of a physical SIM if you have a compatible device, such as an iPhone XS, Samsung S20 or Pixel 3 or newer. If you opt for an eSIM, this keeps your physical SIM slot free for a Cocos 4G SIM. This essentially turns your phone into a dual SIM phone.  You can get an eSIM for your compatible phone at a Telstra Shop, more info here

Example image below is an iPhone XS with a Telstra eSIM on the Cocos 4G network.  Telstra mobile calls & SMS are possible over the Cocos 4G network.
