MiFi is a compact wireless device that creates a mobile Wi-Fi hotspot using a cellular data connection. It allows multiple devices, such as smartphones, laptops, and tablets, to access the internet from anywhere with mobile coverage. MiFi combines the power of a modem and a router into one portable unit.
Quick Definition
MiFi is a portable router that connects to a cellular network and broadcasts a secure Wi-Fi signal, enabling multiple devices to access the internet on the go.
How Does MiFi Work
A portable Wi-Fi unit operates by:
- Connecting to a 3G, 4G, or 5G mobile network using an internal SIM or eSIM.
- Broadcasting a local Wi-Fi network to nearby devices.
- Enabling multiple users to share one mobile internet connection.
Many models support up to 10–15 connected devices and offer rechargeable batteries that last from 6 to 24 hours.
MiFi vs Mobile Hotspot vs eSIM
When exploring mobile internet options, it’s common to compare dedicated hotspot devices, mobile phone tethering, and digital SIM technology. Each serves a similar purpose—getting you online without fixed broadband—but they differ significantly in setup, usability, and ideal use cases. Understanding these distinctions helps travelers, remote workers, and casual users make the right choice based on their lifestyle and connectivity needs.
