What Is MIFI and How Does It Work?

MiFi devices are mobile WiFi hotspots that you can take with you on the go. So if you’re out and need to connect to the internet, a MiFi device can give you access so you can continue working without needing to worry whether the train, café, or wherever you’re working from has internet access. In our MiFi guide, we’ll walk you through what they are and how they work.

What Is a MiFi Device?

A MiFI device is a bit like a WiFi router you can carry around in your pocket! It’s essentially a portable mobile hotspot that you can take with you wherever you go so you can stay connected to the internet. It works in a similar way to your phone’s hotspot, but it is generally much more powerful and you can connect multiple devices with ease.

Who Owns MiFi in Ireland?

MiFi is actually a brand name rather than an abbreviation and it varies from country to country as to who owns the rights to the trademark. In Ireland, ‘MiFi’ is owned by Inseego, which also owns the rights in The United States, Canada, and Mexico.

How Does MiFi Work?

MiFi works in a very similar way to how your home broadband connection works, but this time there are no cables and you don’t need to keep the router in one place.

The main difference with a MiFi router is that it connects over a mobile connection rather than over a wired fibre connection meaning that it relies on the same connection as your phone. They are usually battery powered instead of plugged into the main so you can carry them about!

Does a MiFi Device Use a SIM Card?

Since a MiFi device connects over the mobile network, you need to get a separate SIM card to put in your MiFi so it can use a mobile plan from your broadband provider. Depending on the provider or the way you buy your MiFi device, you’ll either get a SIM already installed in your device with a data plan, or you will need to get a new one SIM only plan if you have bought your MiFi device independently.

How Do I Set Up My MiFi Device?

Setting up a MiFi device is really easy. All you need to do is follow these steps to get it all set up and ready for you to use:

1. Charge the Device
   MiFi devices will already be partially charged as soon as you take it out the box. Sometimes though, the device might be completely out of battery so you’ll need to leave it charged before you switch it on.
2. Insert the SIM Card
   It might be that your device already has the SIM card included (or may possibly be using an eSIM) which means you can skip this step. However, if you have your own SIM that you want to use, it’s best that you put it in before the MiFi is booted up.
3. Power Up
   After you’ve inserted the SIM card you need to power up the device. Depending on the model and the brand, the ON switch might be different. In any event it should be simple to find since it’ll either be already labelled or have the universal power button symbol on it.
4. Connect Your Devices
   After it’s been powered on, you should use another device to connect to the WiFi signal. Search for your MiFi’s device name and type in the password. These are usually written in the instructions or are in the box.
5. Change the Default Settings
   Next, you might want to change the default settings so you can add extra security. You should change the same of your MiFi device and the password to something more secure and personalised. You’ll usually find out how to do this in the instructions.

Is MiFi Better Than WiFi?

There are lots of advantages that MiFi has over WiFi, especially when it comes to mobility and the flexibility of selecting your own plans so you can manage your data. However, there are of course some drawbacks when it comes to MiFi where a WiFi network might be better.

What Are the Advantages of a MiFi Device?

Here’s a quick overview of the advantages and the disadvantages of MiFi devices:

How Fast Is MiFi?

Like mobile phone plans, the internet speeds for MiFi devices can depend on the type of plan you take out and the amount of data you’ve bought. Like mobile phones, you can take out a bill pay plan or a Pay As You Go plan to make sure you have the data that you need at any one time. MiFi speeds can range from the same as 4G mobile connections up to 5G.

Does MiFi Have Good Coverage?

The coverage for your MiFi will ultimately depend on the coverage of your provider. You should definitely check the coverage in your area to see which providers have the best signal in your area. It might also be worth asking around for advice from neighbours to see if there’s a preferred provider that works best round where you live.

Which Providers Offer MiFi?

Many different broadband providers have MiFi options you can take advantage of. Here’s a table present the best one on the market from the three leading providers:

What’s the Difference Between Mobile Broadband and MiFi?

Mobile broadband is generally a router that has no physical connections to fibre or ADSL and instead runs off the mobile network. The reason for this is generally due to the lack of coverage in rural areas in Ireland, and mobile broadband, especially with 5G, provide a great alternative.

MiFi is exactly the same as mobile broadband but is marketed differently. Although it functions in the same way that you use it through the mobile network, MiFi is designed to be portable and to be carried with you so you can use the internet on the go. Many companies will offer mobile broadband and MiFi as the same thing, for example:

• Eir mobile broadband
• Vodafone mobile broadband
• Three mobile broadband
