eSIMs, or embedded SIMs, are digital SIM cards that you can activate remotely without needing to switch out your physical SIM card. This is particularly beneficial for travelers as it allows for quick and easy setup, eliminating the need to purchase and insert a new SIM card when you arrive in a new country.

• Cost-Effectiveness: Often more affordable than roaming rates or local SIM cards.
• Flexibility: Change plans or providers as needed without physical intervention.
