I love using eSIMs. Someone steals your phone, they cannot pull the SIM to prevent you from tracking it.
All they can do is shut it off. The moment it gets turned back on, you got a location. I'll never use a physical SIM card again if I don't have to.
Installing and activating an eSIM was pretty easy with AT&T... not sure about other carriers.
Gave my daughter an iPhone 11 Pro that was unlocked. Didn't have a SIM card in it or any plan setup for it at the time. Just went to the AT&T website on her phone (via WiFi obviously) and had an eSIM installed and activated in about 10 minutes.
