4G. It’s waiting for you.
- 4G explained
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, will take seconds on 4G.
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.
However, 4G speeds will still vary depending on location and the number of people using the service. Check out the Ofcom website for more info.
You'll need a few things before you can get started with 4G:
- A 4G phone or device from our range
- A 4G sim (these come with all 4G phones sold since June 2013)
- The latest software
- 4G coverage
- A 4G tariff
- Live status checker
If you're having problems with your signal or mobile internet, take a look at our Live Status Checker to keep tabs on any faults in your area.
How to use the status checker
- Go to our Live Status Checker page
- Select your service: voice (phone calls), data (mobile internet) or text
- Type in your postcode, address or nearby landmark
We'll show you live info about any problems with our 2G, 3G and 4G networks in your area. We update hourly, so issues might not show up immediately.
You can also use the status checker to find out about any maintenance work we're doing in your area, and when it'll be completed – check the table below the live info.
- When is 5G coming?
We now have 5G in parts of most major UK towns and cities, as well as lots of smaller towns and villages. To see whether 5G has arrived in your area visit our coverage checker.
While we’re focusing on getting ready for 5G, we continue to invest around £2m every day in our existing 4G network, which will be the supporting backbone for 5G for many years to come. In January, for the second year in a row, we were named as having the best network coverage at the annual uSwitch awards, and we also earned the best network performance award at the Mobile News Awards 2019.
