eSIMs are more and more popular among travelers due to its convenience, ease of use and security. However, are eSIMs safe for banking? This article explores the safety of using travel eSIMs for online banking.

What is a travel eSIM?

A travel eSIM is a digital SIM embedded in your device, specifically designed for short-term use by travelers abroad. Unlike traditional physical SIMs, travel eSIMs allow you to activate local or regional data plans instantly without visiting a store or swapping cards. By scanning a QR code or using a provider’s app, you can connect to a local network in minutes, making it ideal for accessing navigation, communication, or banking apps while traveling.

Are eSIMs safe for banking?

When it comes to online banking, security is a top priority. eSIMs adhere to strict security standards set by the Global System for Mobile Communications Association (GSMA), ensuring robust protection for data transmission. These standards require eSIMs to use encrypted connections, which safeguard sensitive information, such as banking app logins and transactions, from interception.

How safe are eSIMs compared with physical SIMs?

Here are some security advantages of eSIMs over physical SIM:

• Embedded Design: eSIMs are built into the device, preventing physical removal or theft.
• Reduced SIM Swapping Risk: Eliminates the chance of hackers intercepting one-time banking codes or authentication messages.
• Secure Activation: Uses encrypted QR codes or apps to minimize vulnerabilities during setup.

However, like any technology, eSIMs are not immune to risks such as phishing or social engineering, which depend on user behavior rather than the technology itself. To address these concerns, many eSIM providers implement additional safeguards.

For example, Gigago enhances eSIM security with the following features:

• Encrypted Connections: Industry-standard encryption ensures that data transmitted via Gigago’s eSIMs, such as banking transactions, remains private and secure.
• Privacy Protection: Gigago does not share user data with third parties, protecting personal information during travel.
• Secure Activation Process: Gigago’s QR-code-based activation uses end-to-end encryption, preventing unauthorized access during setup.

By combining the inherent security of eSIM technology with provider-specific measures like those offered by Gigago, travelers can use eSIMs for banking with confidence, provided they follow best practices to mitigate external risks.

• Enable Two-Factor Authentication (2FA): Add an extra layer of security by enabling 2FA, such as one-time codes or biometric authentication like fingerprint or facial recognition.
• Use a VPN: When accessing banking apps on public Wi-Fi or even mobile data, a VPN adds an additional layer of encryption to protect your connection.
• Update Software Regularly: Keep your device’s operating system and banking apps updated to benefit from the latest security patches.
• Monitor Accounts: Regularly check your bank and credit card accounts for unauthorized transactions and contact your bank immediately if you notice anything suspicious.
