New to this rodeo. Brought an iPhone 15 home with a sim card from T Mobile (?) only to discover that there is no physical sim card slot. Not for me. Returning the phone tomorrow. This business with the e sim card is too much - especially for travel outside the US. Somebody convince me about the wonders and convenience of having an e sim card in my phone as opposed to a physical one. Apple continues to disappoint. They seem motivated to lose customers - even formerly faithful ones.
