TELUS eSIM Card

Many places put in a physical SIM first because the phone needs to have a data connection of some sort.  This can be achieved by connecting with W-Fi also, but unfortunately some companies or people don't understand the process so they insist upon putting in a physical SIM first.  Bear in mind that in many places, including Canada, eSim is only on postpaid accounts, not prepaid.  It makes no sense to me that a physical sim would be required for "device warranty" particularly in your case, but warranties are generally by serial number not phone number.  Lots of misunderstandings out there.  Good luck.
