What is an eSIM and why use one?

An eSIM (embedded SIM) is a digital alternative to a physical SIM card. It allows you to activate a cellular plan directly on your device without needing a removable SIM. It’s especially helpful when traveling, as you can activate and use mobile data anywhere in the world.

Benefits of using a travel eSIM:

• No physical SIM swapping needed
• Set up before you travel
• Instant data access upon arrival
• Keep your original SIM active for calls/SMS while using the eSIM for data
• Easily manage and switch between multiple plans
• Lower costs than traditional roaming
• More environmentally friendly — no plastic waste
