T-Mobile's latest update enables eSIM on the Samsung Galaxy Note 20 Ultra
eSIM, or Embedded SIM, is a relatively new standard that allows greater flexibility in managing your carrier plans. Devices that support eSIM let you change your service provider or plan through software, and also allow you to have two or more phone numbers on the same handset.
Galaxy Note 20 Ultra eSIM USA
Google's Pixel smartphones have had eSIMS since 2017, and Apple's iPhones since 2018.
Last year's Galaxy S20 and Note 20 series and Z Fold 2, and this year's S21 range also theoretically supports the eSIM technology, but the feature is not enabled in the US, seemingly because of lack of enthusiasm from carriers.
Thus, it's great news that eSIM support has finally come to the T-Mobile Note 20 Ultra and it's likely that support will be expanded to more compatible devices in the future.
Other than the March security patch and eSIM support, the new update also brings "additional updates and improvements," per the changelog.
