However, this is not possible on the iPhone just yet.

Most Android phones with dual SIM cards will allow you to create a clone of WhatsApp and use it with your secondary number. To give you an example, with two numbers on your phone, you might also want two different WhatsApp accounts. It’s called App twinning or App cloning which basically allows you to have two instances of an app working independently of each other. However, there is one particular area where the iPhone will need to catch up with Android phones and we’re not quite sure if Apple will allow this in future iOS updates. The functionality of the iPhone using either two physical SIM cards or using an eSIM as well as a regular SIM card is expected to be the same so whenever Apple enables eSIM functionality on the iPhone XS and XR, expect it to work much like what we’ve described above. When you receive an incoming call, iOS 12 lets you know which SIM the call is coming through and the Call History screen also shows which SIM was used for each call.

A small button appears on top the dialter that lets you switch between the SIM cards on the phone. When you’re calling someone, you can select which SIM you want to use for outgoing calls.
