## Description

Dual Sim / Multi Sim Selector is a powerful Chrome extension designed for Android devices with dual or multiple SIM cards. It automatically chooses the appropriate SIM card for outgoing calls based on user-defined rules such as user account, contact, groups, phone number patterns, or roaming status. This extension enhances the calling experience by eliminating manual SIM selection, saving time and reducing errors.

Note that this extension requires permissions to monitor and manage outgoing calls and cannot function on devices without multiple SIMs. It does not handle incoming calls, SMS management, ringtone settings, or data SIM changes. Some device manufacturers implement SIM selection at the phone app level, so a default SIM must be set in system settings for the extension to work seamlessly. Overall, it's an essential tool to streamline multi-SIM usage and improve phone call management.

## Review summary

Users find the app useful for dual-SIM management and for blocking calls via a chosen SIM, with some praising the trial version. However, Android 15 compatibility problems and broader reliability issues are repeatedly reported, along with a confusing setup process, unclear payment flow, and limited developer support. Overall, the app has potential but faces significant stability and support challenges on newer devices.

### Pros

- Ability to block a caller and select which SIM card to block.
- Overall useful and important app for dual-SIM management.
- Serves as a helpful workaround for dual-SIM issues on Samsung devices.
- Trial version is great for testing before purchasing.
- Generally positive reception with reviewers calling it 'great' or 'good'.

### Cons

- Not working on Android 15; compatibility issues reported across multiple devices (e.g., OnePlus models).
- General non-functionality and unreliability on various phones.
- Setup is confusing and complex, with many settings and unclear defaults.
- Trial-to-paid path is unclear or the full version has no easy purchase option.
- Lack of clear developer support or easy way to contact for help.
