What is mobile broadband?

Mobile broadband lets you connect to the internet using mobile phone signal.

It offers portable web access on the move so you can get online on your laptop, tablet or mobile wherever you are, provided there is a 3G or 4G connection available.

It is relatively cheap compared to most standard broadband packages and is more flexible, with most providers offering short term contracts and a number of package options.

Why should you get mobile broadband?

There are a number of advantages:

  • More flexibility: Mobile broadband allows you to access the internet anywhere with a mobile signal, giving you more freedom to browse the web on the move.

  • Easier to set up: It is quicker to set up than standard home packages which often take weeks to install. Once you have your mobile broadband device and have topped up your data, you can just plug in and go.

  • Cost: Compared to standard broadband packages, it is relatively cheap. You avoid the high costs of line rental and superfast connectivity, and flexible contracts can run month-to-month or on a pay as you go basis.

Are there any drawbacks?

Yes, while mobile broadband can be cheaper, there are a few things to be aware of:

  1. 1.

    Availability: Broadband access will rely on the strength of mobile phone signal in your area so if you have poor reception or 4G is unavailable, your connectivity will suffer. Try Ofcom's mobile coverage checker to check mobile signal in your area before you commit to a mobile broadband package.

  2. 2.

    Speed: This will vary and depends largely on your location and how many other people in the area use the service at any one time. You can check average speeds in your area on the Broadband.co.uk website.

  3. 3.

    Data limits: Most mobile broadband data limits are considerably lower than standard broadband, and the higher limits come at a much higher cost. If you use services like Netflix or Skype, or download large files, you could end up paying a lot for your data.

  4. 4.

    Battery drain: 3G and 4G internet will drain the battery life of your laptop or tablet much faster than a standard WiFi connection.

How can you get mobile broadband?

Getting connected with mobile is usually quicker and easier than setting up home broadband but there are a few things you will need to do before you start:

  • Check availability in your area

  • Buy a broadband device

  • Register with a mobile broadband supplier

Where can you get mobile broadband?

Mobile broadband availability depends on the strength of signal in your area.

Less populated areas can sometimes have poor or no signal at all, so check with your supplier before you buy to make sure you have access to good reception.

How fast is mobile broadband?

You can expect it to be slower than standard home broadband, with reception in your area and the individual supplier also affecting your speed.

You should also keep in mind that the speed advertised by your provider may not be the speed you actually get.

You also need to consider your internet usage requirements. For example, if you spend a lot of time gaming or streaming video, it is unlikely that mobile broadband will offer the speed you require.

What mobile broadband device should you get?

There are three main types of mobile broadband device for you to choose from:

USB dongle

The most popular mobile broadband device, USB dongles are typically used for providing laptops with an internet connection on the move.

Your laptop may already come with a dongle fitted but you can also buy them from as little as 15 from a mobile broadband provider.

You just need to plug your dongle into the USB port on your laptop and activate your data with your network provider. You can pay monthly for your data or top it up as you need it.

SIM card

A SIM only internet plan lets you connect to the internet via your tablet or iPad.

Just like a mobile phone contract, a broadband SIM can be paid for on a monthly or pay as you go basis.

This gives you the flexibility to switch providers or swap the SIM between multiple devices.

Wireless mobile broadband (MiFi)

MiFi is good if you are looking to replace your home broadband as you can connect several devices at the same time, but it is usually more expensive than a dongle or SIM.

A MiFi device creates a secure wireless hotspot which allows multiple wireless devices to share the same connection. This process is called tethering.

Most smartphones with a 4G connection can be used as a hotspot but you should check with your network provider for tethering restrictions as you could be charged for exceeding your limit.

Choosing the right supplier

Before you get online you need to register with a mobile broadband provider.

Suppliers like EE, Vodafone and Three offer a range of contract terms with varying connection speeds and data limits.

Depending on the network coverage in your area, you may have the option of 4G internet which offers faster speed and improved connectivity.

What are your data limits?

It is usually measured in gigabytes (GB) and the amount you opt for will be determined by your browsing habits.

Your data limits will be based on how frequently you access the internet and what you use it for.

Data limits will vary between suppliers but you are unlikely to find unlimited data in a mobile broadband deal. Typically, you can expect data to be capped at 1 GB to 5 GB, although you should check this with your network provider.

Many suppliers will provide an app for tracking your data usage to make sure you stay within your limit.

The verdict

Mobile broadband is ideal if your internet usage is low. It is also a good option if you are a student, as it tends to be cheaper than standard broadband.

4G is becoming more common and mobile broadband deals are always changing, so the speed and data limits available to you will constantly improve.
