Internet

Most towns and cities in the UK offer some form of public access to the Internet. If you're staying in a hotel they may include Internet facilities as part of their service, and free Internet access is often available at libraries. Many pubs, cafés and museums also offer free Wi-Fi Internet access, so you can sit down and use your laptop, tablet or phone.
Internet cafés usually charge for computer use by the minute. Internet access is generally very cheap, but it is most reasonable during off-peak times.
VoIP (Voice over Internet Protocol) is a way of communicating via your computer and most Internet cafés will have at least one such system installed.
