OnePlus has officially commenced the rollout of its July 2026 software update for its flagship smartphone, the OnePlus 15 🏆. While monthly patches are usually minor maintenance releases, this specific OTA update brings a massive structural upgrade to the phone’s cellular capabilities: Dual eSIM support.
Beyond the major connectivity overhaul, the update bundles a variety of security patches, UI refinements, and multimedia enhancements. Here is everything included in the latest build.
Dual eSIM Support
The absolute headline feature of the July 2026 update is the native activation of Dual eSIM capabilities. This feature allows OnePlus 15 users to host and maintain two digital eSIM profiles actively running at the exact same time. For frequent international travelers and business users who manage multiple network providers without swapping hardware plastic, this is a massive quality-of-life improvement.
4-SIM Community Question: One critical detail that remains unverified is whether the OnePlus 15 can simultaneously manage two physical nano-SIM cards alongside the two active eSIM profiles to achieve a 4-SIM standby state. Early community testing and user reports suggest that the physical hardware SIM slots are automatically disabled the moment two digital eSIMs are activated. However, OnePlus has yet to issue an official confirmation clarifying the exact allocation layout.
Everything New in the July 2026 Changelog
Apart from the major cellular upgrade, OnePlus has loaded this build with systemic optimizations across performance, biometric security, and creative optics.
