In one sentence
The Samsung Galaxy S25 eSIM is the built-in digital SIM in the Galaxy S25 range that lets you add a mobile plan by software instead of inserting a physical SIM card.
In detail
The Galaxy S25 range, released in early 2025, includes an embedded SIM chip that can store mobile plans (called eSIM profiles) downloaded over the internet. This works alongside a regular SIM on most models, so you can keep your home number active while using a separate data plan abroad. SIM tray arrangements differ between regions and models, so it is worth checking the specifications for the exact phone you own. Your phone also needs to be carrier-unlocked, because a locked phone may refuse a plan from a different provider. The Galaxy S25 runs Android well above the Android 10 minimum needed for one-tap install, so the setup is straightforward.
How it works
After you buy a plan, the eSIM details are delivered to you by email with an Install on Android button. Tapping it opens the Galaxy S25's eSIM setup screen, which downloads the plan and adds it to your SIM manager. You then choose which plan to use for mobile data in Settings, and you can switch back to your home SIM at any time.
Why travellers should care
With an eSIM on your Galaxy S25, you can set up local data before you fly and switch it on when you land, with no airport SIM queue and no tiny card to lose. Keeping your home SIM in the other slot means you can still receive calls and text codes from your bank. Fresim plans cover 190+ destinations, and prices vary by destination and are set by each store.

Example
Priya, a travel blogger, flies from Melbourne to Lisbon with her Galaxy S25. The night before departure she opens her Fresim email on the phone, taps Install on Android and the plan is added in a minute or two. Her home SIM stays in the other slot for calls and text codes. When she lands, she switches mobile data to the travel eSIM in Settings and is online straight away. Her partner uses an older phone, so Priya shows him the QR code on her laptop screen and he scans it to install his own plan.
Key takeaway
The Galaxy S25 supports eSIM, so on an unlocked phone you can install a travel plan with one tap before you leave home.
