iOS 16 introduces a useful new feature for dual-SIM iPhone users: the ability to sort messages per SIM in the Messages app. This feature is particularly beneficial to those who have both personal and work lines set up on a single iPhone.
"Messages now supports the ability for customers with a dual SIM iPhone to filter their messages based on their SIMs," says Apple's release notes for the second beta of iOS 16, which was made available to developers for testing on Wednesday. When enabled, the feature filters both iMessages and SMS/MMS messages.
It appears that per-SIM message sorting requires enabling message filtering in the Settings app under Messages → Filter Unknown Senders. Then, users can tap on the icon with three dots at the top of the Messages app, which opens a menu with options to sort messages based on "All Lines" or individual SIMs, such as Personal, Business, or Travel.
iPhone XS and newer models are equipped with both a physical nano-SIM card slot and a digital eSIM, allowing for dual-SIM functionality. This means you can have two lines of service on one iPhone, which is useful for having personal and business lines on a single iPhone or for purchasing data-only plans via eSIM while traveling abroad. Starting with the iPhone 13 lineup, dual-SIM mode also works with two eSIMs.
iOS 16 is currently in beta for registered Apple developers. The update will be released to all users with an iPhone 8 or newer around September.
