What is 4G?

4G is up to five times faster than 3G, making it much easier to watch videos, play games, tweet and browse on your phone. Downloading a 10-minute video clip, which takes minutes over 3G, takes seconds on 4G.

How it works

Our 4G network will take over the frequency used by analogue terrestrial TV. This signal passes through walls more easily, so we'll be able to give you great indoor coverage.

What is a Bolt On?

Bolt Ons are extras you can add to your account and pay for them monthly at the same time. They can range from buying 50 picture messages to discounted international calls.

You can see our range of Bolt Ons here.

Don't forget - we are giving you this bolt on at no extra cost to you.

Have I got the latest software? How do I tell?

Not having the latest software could mean that 4G won't work on your phone. But don't worry, is free and easy to do. To find out if you need to update your software go here.

You haven't given me 4G access. Why not?

If you're on Pay Monthly and have a data allowance of less than 500MB we've not added 4G. Its because we think you need at least 500MB data allowance each month to get the most out of 4G. If you're on Pay As You Go, we've not forgotten about you. We're looking to open up the possibilities of 4G to you soon.

What is O2 Business offering? And when?

We're also opening up the possibilities of 4G to a number of our existing business customers. We've already started and will continue with small groups throughout the year. We'll be in contact with them when it happens to tell them the good news. Please contact your account manager or our customer service team on 0800 977 7337 if you want to find out more about 4G and how it can benefit your business.

Will this affect my phone's battery life?

The phone will always try and connect to the strongest network available and as a result if a customer is in a 3G area the phone will be continuously searching for a 4G connection. The best tip is that if a customer is in a no 4G (or patchy 4G) area they should turn 4G off. This will save on Battery life as the phone will no longer be searching for the Network.
