A MiFi is a battery-powered pocket router. It takes a SIM, creates a small WiFi network, and travels with you — which is the one thing a home router cannot do and the reason to consider one.
The honest first question is whether you need one at all, because your phone already does this.
MiFi or just tether from your phone?
Most phones can share their connection over WiFi. If you need internet for a laptop occasionally, tethering costs nothing extra and there is no second device to charge or lose.
| Choose a MiFi if | Tethering is enough if |
|---|---|
| Several people or devices connect regularly | It is just your own laptop, occasionally |
| You need it for a full working day | Short sessions |
| You want a separate data allocation | Your phone bundle has room |
| Draining your phone battery is a problem | You are near a charger |
The battery point is the practical one. Tethering flattens a phone quickly, and a MiFi keeps your phone available for calls.
Who they suit
- People who work from varied locations — sites, client offices, coffee shops.
- Households without fixed internet who need something that also travels.
- Groups sharing a connection, on a trip or at an event.
- Anyone wanting data separate from their phone allocation.
What to check
- Battery life against how long you need it running.
- How many devices it supports at once.
- Whether it is network-locked, which limits changing provider later.
- Whether the data is portable, unlike home packages which are usually address-locked.
- Band support, particularly if you want 5G rather than LTE.
Not a home internet replacement
A MiFi will serve a household at a push, but a fixed router is faster, has no battery to manage, and usually comes with a much larger allocation for the money. If the device rarely leaves the house, buy a home package instead.

Frequently asked questions
Is a MiFi better than tethering?
For several devices, long sessions, or to protect your phone battery, yes. For occasional single-device use, tethering is usually enough.
Can I use a MiFi at home?
Yes, but a fixed router is faster and usually cheaper per gigabyte.
Does it need its own SIM?
Yes, and that SIM requires RICA registration like any other.
Can I move it between provinces?
Generally yes, unlike home packages which are often address-locked. Confirm the terms.
