Apple has been introducing the newest available technology with their products each time a new iPhone model appears.
This time they introduced somenthing for people that want to use more than one simcard on their device.
We are talking about dual sim option, but not the traditional one. For the time being you could insert one physical simcard and use eSIM for the second one.
However thanks to iPhone 13 you will be able to do it quite different. You can let go of the physical simcard and use to eSIMs.
We know what some of you think, if I use 2 eSIM I can still insert the physical one right ?
No you cannot you can only device to use two eSIM or eSIM with a physical one.
