After AT&T launched their support of the iPhone eSIM yesterday and Verizon doing so today, T-Mobile remains the major US carrier that doesn’t support it yet. That will however change by the end of 2018.
According to PCMag the nations third largest carrier will be rolling out an app to enable the service for their prepaid customers before the end the month.
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.
While it will only be for prepaid customers initially, it is good to see that T-Mobile will be bringing support for the dual-SIM iPhone lineup. All three of the 2018 devices, the iPhone XR, iPhone XS, and the iPhone XS Max have dual-SIM support. One is a physical SIM that we all are use to using while the second is an eSIM.
eSIM technology is not new. It has been in the Apple Watch for example on the Cellular models and Google has taken advantage of it in the Pixel 2 for Project Fi customers. Apple, with the exception of the models sold in China, went with the eSIM technology for customer support (easier to change your carrier) and overall savings of size on the devices.
