One of Apple's most noteworthy upgrades to iPhone XR and iPhone XS was the addition of eSIM and dual physical SIM support, allowing users to easily switch between mobile operators and multiple phone numbers. Unfortunately, the major US carriers were not ready to support the features when the iPhone was delivered, a situation that Verizon apparently is set to launch next month.
According to a new 9to5Mac report, an internal note from Verizon states that the carrier will begin eSIM and physical SIM activations for dual SIM configurations in early December. In spite of the iPhone hardware support for the feature, Verizon discovered that the iPhone's other SIM was locked by using its older CDMA network instead of LTE, resulting in lower speeds and connectivity issues. The company said it would work with Apple to solve the problems.
Similarly, AT & T discovered that double SIM users encountered problems with Visual Voicemail, which prompted it to take out the first support for the feature. T-Mobile and Sprint both relied on supporting the feature at the beginning, saying that they were working with software updates to enable support; T-Mobile has recently said that it will "get a solution available before the turn of the year."
U.S. Customers currently represent quite a small part of the global demand for eSIM and dual physical SIM solutions. Asian and European users rely on two SIMs to switch phones between business and personal lines, as well as domestic and international carriers. The exclusion of dual SIM support was previously considered as an obstacle to iPhone adoption by customers in some countries, and discussed as a possible China-exclusive addition in addition to the official announcement.
It is unknown at this time if Verin's dual SIM support will be included in an iPhone carrier update, which may be Verizon-specific, or a full iOS update with the potential for multi-carrier support. Verizon's early December timeframe suggests that the problem should be addressed in IOS 1
