Nice I think I’ll keep it simple like that. Thanks! What’s the benefit of multiple SIMs? 

 Depends on your situation.

For me:

SIM - always a local phone number to use IRL

Tello eSIM - I use Tello to keep previous IRL phone numbers around

Silent Link eSIM - international internet without KYC.

Payed SMS services - for registering NoKYC handles online (like with Twitter).
 

 So can I use both a physical sim with a new number and an eSIM with my old number at the same time? 

 The maintenance cost across user and profiles cannot be understated. It's similar to the cost of maintaining a complex #Bitcoin multisig where you have to manage a node, interfacing computer, and firmware on many devices. Don't underestimate how much friction that adds.
