No sooner had EE announced an incentive for its customers than O2 follows with its own. O2 customers can now access free Wi-Fi throughout the UK without even having to sign in ever.

O2 Wifi Extra is the evolution of the network's free Wi-Fi service, which offers connection to hotspots placed in numerous locations around the UK, including inside McDonald's restaurants, Costa Coffee shops and the whole of Westminster, Kensington & Chelsea and Canary Wharf in London.

There are 11,000 locations across the UK that have O2 Wifi Extra hotspots and O2 customers will now be able to connect to them on their travels, without even having to open an app or signing in.

A customer with a compatible device - either smartphone or tablet - will automatically connect through authentication of his or her SIM card.

The service will also judge which is offering the strongest connection, the nearest hotspot or the phone's 3G or 4G signal, and use that one to give the best experience.

O2 also promises that the service is fully monitored and secure.
