Apple's new dual SIM feature, available with iPhone XS and XR models, became enabled with iOS 12.1 on Tuesday, but the three largest mobile operators in the United States do not support the launch feature.
IOS 12.1 Update
Although iPhone now supports dual SIM functionality, all three major US carriers – Verizon, Sprint, AT & T – are not currently doing. Apple's technology relies on a primary physical SIM card and virtual eSIM, each of which can be set up as a separate line.
Verizon, the biggest of the three, looks like the biggest problems ahead, reports PCMag . Referring to people familiar with the matter, the publication shows more limitations to Apple's solution.
Currently, when a Verizon account is added to the secondary SIM card, it is downgraded to 2G CDMA functionality that lacks the ability to support MMS, even less FaceTime or other data-intensive tasks. Verizon also says that 30 percent of your cell pages are LTE-kun, which means that users will experience significant coverage pressure if support rolls out as it is.
These disadvantages will be present until a repair can be implemented, something Verizon says it works with Apple.
"Based on our discussions with Apple, we believe that these concerns will be resolved quickly and you should be able to add our amazing Verizon service to your secondary line before the end of the year," Verizon said in a statement. "Until the Secondary The line can deliver Verinson's complete package of voice and high speed data services, we will not enable Verizon service on any eSIM. This includes our own customers 'iPhones with dual SIM features, as well as iPhones on competitors' networks. "
When the issues are reduced, Verizon will support dual SIM functionality for iPhone for two simultaneous Verizon lines.
T-Mobile also says it is currently working to support the feature and will soon activate it. when the software is ready. AT & Ts official position on dual SIM is unclear, but MacRumors referring to a local store manager reports that the feature is currently not supported.
Apple in September showed that the latest iPhone The XS and XR model supports dual SIM functionality, allowing owners to use two mobile plans on a single device without replacing SIM cards. The solution is ideal for roaming out of the country or to set up work and personal numbers to both go to the same phone.
A common smartphone feature in Asian countries like China, two SIMs is less popular in the United States, but the inclusion in the latest iPhones can increase the adoption.
Dual SIM was not available since iPho Ne XS or XR launched in September and October, but was instead implemented in the recently released IOS 12.1 update.
