Reliance Jio’s portable Wi-Fi hotspot (commonly known as JioFi) spiked the popularity of Mi-Fi (short for Mobile Wi-Fi) devices in India last year. Mi-Fi devices are small hot-spot gadgets that work as personalised pocket routers.

So long, smartphones were the only source of tethering as an Internet hotspot for other devices, including laptops and tablets. However, this is good enough for tasks that require limited data. Also, smartphone tethering drains the battery much faster, restraining the extent of use. While data dongles address these two challenges, most support only a single device at a time.

A Mi-Fi device comes across as the best solution for dedicated Internet on-the-go. It requires a mobile sim card that allows access to the Internet. A Wi-Fi chip lets it create a network and connect multiple devices via Wi-Fi simultaneously. A dedicated battery allows longer usage.

In the present market scenario, it is important to cross-check a few features while purchasing a Mi-Fi device. Pay attention to the connectivity range the device supports. Choose a device that offers 4G or LTE connectivity (4G device usually supports 2G and 3G networks, too).

Ensure whether the device is ‘unlocked.’ A locked device is compatible with only a single service provider’s sim and does not accept any other. An unlocked Mi-Fi device, on other hand, gives you the flexibility of selecting your own service provider. Features like USB compatibility, expandable SD card slot and support for higher number of simultaneous Wi-Fi devices (at least 10) will bring in more benefits.

Today, JioFi is the most popular Mi-Fi device in the Indian market. Let us look at some other options and explore their features.
