From there, go to “Connections,” then select “SIM card manager.” Here, you’ll find options to manage both SIMs, allowing you to customize settings like call preferences, mobile data usage, and notifications for each SIM. Just follow the prompts to complete the setup.
Can I use both SIM cards for mobile data on the Samsung S21 Ultra?
Yes, the Samsung S21 Ultra allows you to use both SIM cards with mobile data, but you need to manually select which SIM you want to use for data services. When setting up your Dual SIM functionality, you can choose a default SIM for mobile data usage. This option is helpful if you want to use a specific plan that offers better data rates or coverage.
You can also switch between SIMs for data at any time by going back to the “SIM card manager” in the settings. This flexibility allows users to optimize their data usage based on changing needs or roaming situations, ensuring that they pay the least for their data usage while staying connected.
What happens when I receive a call on one SIM while using the other?
When you receive a call on one SIM while actively using the other, the Samsung S21 Ultra typically allows you to answer the incoming call. If you’re engaged in a call on one SIM, the phone will generate a notification for the incoming call on the second SIM. You’ll have the option to either decline or answer the call, depending on your preferences.
However, it’s worth noting that if you are already using one SIM for a call and do not answer the incoming call on the other, it will go to voicemail if that feature is set up. This functionality ensures users can stay connected while managing multiple lines efficiently, making the S21 Ultra a powerful tool for balancing personal and work communications.
Can I receive text messages on both SIM cards simultaneously?
Yes, the Samsung S21 Ultra supports simultaneous text message reception across both SIM cards. This means that whenever someone sends you a text message, it will be received on the respective SIM that is associated with the sender’s contact number. This allows for uninterrupted communication across both personal and work-related messages.
You can also manage settings for notifications and message apps, so you can easily distinguish which SIM the message has arrived on. Whether you want notifications for both or opt to silence one while using the other, the flexibility of handling messages on two SIM cards adds to the user’s convenience.
Is it possible to make a video call using Dual SIM on the Samsung S21 Ultra?
Yes, you can make video calls using either of the SIM cards available in your Samsung S21 Ultra. Whether you are using a third-party application like Zoom or Skype, or you prefer the built-in voice and video calling options, you can choose which SIM to use for your calls. During the call setup, simply select the SIM you prefer to use for your video call.
This feature is incredibly useful for professionals who may need to make business video calls using their work number while still maintaining their personal contact number. The ability to switch between SIMs means that users can easily manage their communication needs based on the context of the call.
Are there any limitations when using Dual SIM on the Samsung S21 Ultra?

For instance, you cannot use a SIM for both voice calls and mobile data simultaneously. If one SIM is in use for a call, the other SIM cannot be activated for data until the call ends. Additionally, network compatibility may vary, so it may not work with every carrier.
Another important consideration is the storage and performance of the device. Although the Dual SIM capability is designed to enhance user experience, simultaneous use may have an impact on battery life and overall performance, especially if both SIMs are frequently in use. Therefore, users should monitor their usage patterns to ensure both SIMs function optimally.
How do I troubleshoot issues with the Dual SIM feature?
If you encounter issues with the Dual SIM feature on your Samsung S21 Ultra, the first step is to check the settings to ensure both SIMs are activated. Go to the “SIM card manager” in the “Settings” app and confirm that both SIMs are enabled for calls, texts, and data. Additionally, ensure that your carrier settings are up to date for optimal performance.
If problems persist, consider restarting your device, as this can often resolve temporary glitches. If you’re still experiencing issues, it may be helpful to remove and reinsert the SIM cards or contact your service provider for assistance.
