@userHUKIGah0nH , I hate to tell you, but you'll be waiting for a very long time for the update to support esim in the US because the people who bought the S20's, Z Fold 2's, and Note 20's have all been waiting for the same update about a year in some cases and have still not received support for esim. Samsung knew the functionality was not there when they annonced the product but chose to lie on their website about it so they would not lose preorders. Same tactic they have been employing since the S20 released and then they changed the website after the return window for preorders ended. Sneaky huh? Add in the phone is running blazing hot for allot of consumers and this phone release is looking allot like the Note 7 boondongle. I say guard your wallet, don't invest in something that "may come", and get exactly what you want that has the functionality today.
