As expected, the major carriers here in the United States have all indicated that eSIM support for this year’s iPhones is not here. Further, it won’t be until late this year. That support is necessary for the dual-SIM functionality of the iPhone XS, iPhone XS Max, and iPhone XR.
The ability to enabled dual-SIM support came yesterday to these iPhones thanks to the iOS 12.1 update. With the exception of China, the XS, XS Max, and XR models all use one physical SIM and a second eSIM. In China, because of local laws, a physical dual-SIM version is available.
AT&T, T-Mobile and Verizon all plan to support the iPhone dual-SIM feature once they sort out support for the eSIM itself. eSIM technology is not new and, in fact, these carriers who sell the Apple Watch cellular version already support eSIM. But for the iPhone, it is a bit more complicated as you have things like visual voicemail and other phone specific things.
All three carriers are actively working on issue found in testing but equally, all three are indicated that the feature should roll out by the end of 2018. Sprint, the nation’s forth largest carrier, has given no indication that they will support the feature on their network.
