Japan eSIM vs Pocket WiFi: How Do They Work?
Both eSIM and Pocket WiFi provide internet access, but they function differently.
What is an eSIM?
An eSIM (embedded SIM) is a digital SIM card built into your smartphone. Instead of inserting a physical SIM, you activate a local mobile data plan by scanning a QR code. This allows for instant connectivity without the need for a physical SIM card.
What is a Pocket WiFi?
A Pocket WiFi is a portable router that provides internet access via a mobile network. It works like a hotspot, allowing multiple devices to connect at the same time. Travelers can rent Pocket WiFi devices in Japan to have a dedicated internet source throughout their trip.
