Guide To Mobile Broadband

Discover the benefits of using mobile broadband with O2.

Take a look at the different ways you can use mobile broadband and how you can stay connected anywhere.

Portable WiFi

Portable WiFi devices are an easy way to get on the internet, wherever you are. Otherwise known as mobile broadband or mobile hotspot devices. It creates a WiFi hotspot using the O2 mobile network, that can securely connect up to 10 devices at a time, so your friends and family can all get online as well. It can also boost your WiFi signal and help save your phone's battery. And, it's the ideal solution if you're moving house and will be without broadband for a while.

Mobile Internet Dongles

Stay on top of things with a dongle. No need to worry about all the emails that’ll greet you when you get into the office. Our dongles plug straight into your laptop to get you online when you don't have a WiFi connection. They're perfectly sized to put in your pocket, or your laptop bag, making it easy to browse the internet and send emails when you're on the move.

The right amount of data for you

If you've already got a tablet, dongle or Pocket Hotspot, you'll need a data sim to get online. Simply choose the right amount of data to suit you. Pick a Pay Monthly plan for either 24 months, 12 months or 30 days, or top up when you want with Pay As You Go.
