Does the Samsung Galaxy S25 Ultra Support eSIM?

Yes, the Samsung Galaxy S25 Ultra supports dual SIM functionality. You can typically use a combination of one physical nano-SIM card and one eSIM simultaneously, or sometimes two eSIMs depending on your carrier and region. This allows you to have two different phone numbers or plans active on the same device.

Activating an eSIM on your Samsung Galaxy S25 Ultra is straightforward. You'll generally need a QR code or activation details from your carrier. Here are the common steps:

• Go to Settings > Connections > SIM card manager.
• Tap on Add mobile plan.
• Follow the on-screen prompts, often by scanning a QR code provided by your carrier or manually entering activation information.

Using an eSIM on your Samsung Galaxy S25 Ultra offers several advantages. It provides more flexibility for managing mobile plans, especially when traveling internationally, as you can easily switch between carriers without needing new physical SIM cards. It also enhances security, as an eSIM cannot be physically removed if your phone is lost or stolen.

While the Samsung Galaxy S25 Ultra is designed to support eSIM, compatibility largely depends on your mobile carrier. Most major carriers offering eSIM services in 2025 should be compatible with your device. We recommend checking with your specific preferred carrier to confirm their eSIM support for the Samsung Galaxy S25 Ultra.
