Hotspot & Tethering with eSIM

Hotspot and tethering with eSIM lets you turn your phone's eSIM data into a shareable WiFi network for other devices, like laptops, without needing extra gear.

In Detail

Hotspot creates a WiFi signal from your eSIM-enabled device, allowing you to connect multiple gadgets to the internet using your mobile data plan. Tethering is essentially the same process but can also include wired connections, making it versatile for sharing data on the go. For eSIM users, this means no swapping physical SIM cards—just activate it on your phone and start sharing. It's a game-changer because eSIM plans from providers like Airalo offer flexible data in over 180 countries, helping you avoid expensive roaming fees.

How It Works

Your eSIM connects your phone to a cellular network for data access, then the hotspot feature converts that connection into a local WiFi signal. Other devices join this WiFi network and use your eSIM's data stream, with security features like passwords to keep it private. This process typically uses your phone's built-in software, making it straightforward without advanced setup.

Why Travelers Should Care

Travelers can save money by sharing one eSIM data plan across devices, like using it for your phone and laptop during a trip to Europe, instead of buying separate plans. This is especially useful for digital nomads or content creators who need constant connectivity for work, as it supports reliable internet in places with spotty public WiFi. With Fresim's partnerships, you get access to plans covering 180+ countries, ensuring seamless sharing without surprises.

Example

While backpacking in Thailand, you activate hotspot on your eSIM-equipped phone to share data with your tablet, letting you stream videos and check emails without buying a separate SIM card, all through a Fresim-powered plan from Airalo.
