Does anyone know how the situation is when using a eSIM in an iPhone … Does the other number (eSIM) has access as well to iMessages? What happened to WhatsApp? a second account or the same - how the eSIM behave in the iPhone setup… Got an old Nokia with dual sim and that’s easy - the message is marked relating to sim but end up in the same box - outgoing calls have to be selected (which sim/number) before calling - incoming can have different ringtones

Anyone has experience with this?
 
I have used a second SIM before while travelling to the US; and basically for WhatsApp it just let me carry on using the same account, even though technically it had a different phone number associated with the SIM. I don't use iMessage so can't say what happens there but it was a seamless experience.
