Been my experience as well with T-Mobile and Verizon Wireless. Switching around ESIMs, adding ESIMS, moving ESIM phones between lines has been painless, instant, and fairly easy.
I guess we can judge manufacturers on just 2 phones? So using that same logic here... I have a 14 Pro and a 14 Pro Max. Neither of them have problems. Apple is PERFECT and their Quality Control is PERFECT. I also have had Apple replace a broken phone (dropped) recently (last year) within 5 mins of walking in the store. Excellent.

Alrighty. lol. Guess I need to go create my thread about how Apple's QC is perfect on the 14 Pro. I probably won't get as much attention tho.
