Are there any limitations when using dual eSIM on the Galaxy S24 Ultra

Limitations of Dual eSIM on Galaxy S24 Ultra

1. Active SIM Connections:
- While the device can support two eSIMs, it cannot maintain three active connections at once. Users can have either two eSIMs or one physical SIM alongside one eSIM active at any time. This means that if you are on a call using one SIM, you cannot receive calls on the other[1][4].

2. Preferred SIM Settings:
- Some users have reported difficulties in selecting different SIMs for specific functions (like calls and mobile data). The S24 Ultra may not allow for complete customization of which SIM is used for calls versus data, leading to potential inconvenience for those wanting to manage their SIMs more flexibly[2][4].

3. Carrier Compatibility:
- The effectiveness of dual eSIM functionality may vary based on the carrier. Some users have noted that certain carriers might not fully support the dual eSIM feature, which could limit its usability depending on your service provider[1][3].

4. Battery Life Impact:
- Using multiple SIMs can affect battery performance. The phone utilizes resources to maintain connections across two networks, which may lead to increased battery drain[4].

5. Configuration Complexity:
- Managing dual eSIMs can be somewhat complex, particularly for users unfamiliar with the settings. Users need to navigate through the "SIM Manager" in the settings to configure their preferred SIMs for calls, SMS, and data[5].

In summary, while the dual eSIM feature on the Galaxy S24 Ultra offers enhanced flexibility for users who travel or need multiple lines, it comes with limitations regarding active connections, customization options, and potential battery impact.
