How a travel eSIM works

eSIM technology explained

A travel eSIM is a digital SIM card stored in your device, which allows you to use a cellular network without a physical SIM card. This technology uses a small amount of memory to store the carrier's settings and authentication information, making it a convenient and secure way to connect to a local network while traveling.

Benefits of travel eSIMs

Travel eSIMs offer several benefits, including convenience, security, and flexibility. They eliminate the need to purchase a physical SIM card or deal with roaming charges, and you can easily switch between different carriers or plans while abroad.

Types of eSIMs available

There are two main types of eSIMs: single-IMSI (International Mobile Subscriber Identity) and multi-IMSI. Single-IMSI eSIMs are ideal for travelers who need a single plan for a specific country or region, while multi-IMSI eSIMs allow you to purchase multiple plans for different countries and switch between them as needed.

• Look for an eSIM that supports your device's operating system (e.g., iOS or Android).
• Check the eSIM provider's coverage in Guinea-Bissau before purchasing.

Tips to save data and avoid roaming charges

Use Wi-Fi whenever possible

Use a VPN (Virtual Private Network) to secure your internet connection when using public Wi-Fi.

Minimize data-intensive activities

Be mindful of your data usage by limiting activities that consume a lot of data, such as streaming videos or playing games. Consider using offline maps and guides to help you navigate without relying on data-intensive apps. You can also use data-saving features on your device to reduce data consumption.

• Use data-saving features on your device, such as reducing video quality or limiting background data usage.
• Download maps and guides for offline use to avoid relying on data-intensive apps.
• Turn off location services and Bluetooth when not in use to conserve battery life and reduce data consumption.
• Use a data-saving app to monitor and limit your data usage.
• Consider purchasing a portable Wi-Fi hotspot or a local SIM card for extended periods of travel.
