How T-Mobile’s eSIM iPhone App Works

PC Magazine got an exclusive look at T-Mobile’s eSIM app for the iPhone. It allows users to connect to a new prepaid T-Mobile line without the need for a physical sim card. Apple introduced this capability with the iPhone XS, XS Max and XR. A number of carriers are planning to support eSIM but the T-Mobile system was deemed easier than those from its rivals as it is based on an app and does not a QR Code or in-store activation.
T-Mobile is rolling this app out to its staff for training tomorrow and aims to launch it by the end of the year, according to sources close to the development and rollout. For now, it will only support adding prepaid plans to eSIMs; the thinking seems to be that it will be used for inbound roaming and secondary lines, with customers still going into stores and getting physical SIMs activated for primary lines and family plans.
