When you've finished: quit your VPN first and then log out of BT Wi-Fi before closing your browser.

Please note: We're happy to help you connect to BT Wi-Fi, but you'll need to talk to your company's IT people about your corporate VPN.

You can get up to 10Mbps download speed.

No. Wi-fi is perfect for uploading or downloading large files at high speed. Use is based on time rather than data transfer amount. But please remember that your recipient's email account may limit the amount of data accepted. We suggest that you limit emails and attachments to 10MB. A Fair Use Policy may apply.

Health and safety is at the heart of BT and its operations – we are very conscious of our responsibility to the public, employees, customers and other stakeholders – and take it very seriously.

We monitor industry reports and intelligence about the potential health risks posed by wi-fi and note that there is no credible evidence that the extremely low exposure levels from WLANs pose a threat to human health. The World Health Organization has issued a fact sheet regarding base stations and wireless networks, and its conclusions were: "Considering the very low exposure levels and research results collected to date, there is no convincing scientific evidence that the weak RF [radio frequency] signals from base stations and wireless networks cause adverse health effects."

Absolutely. BT Wi-Fi can be used to make VoIP calls and it's a great alternative to making a standard mobile call.

You can use your BT Wi-Fi voucher or subscription at all BT Wi-Fi hotspots (this means you can log in where you see any BTWi-fi or _BTWi-fi signal).

BT Wi-Fi provides extensive outdoor wireless broadband access in some UK city centres.

Find a wi-fi hotspot shows you a number of ways to find your nearest BT Wi-Fi hotspot, whether you're online, offline or on the move.

You're in a BT Wi-Fi hotspot when you can see the BT Wi-Fi sign and when you can see ‘BTWi-fi’ or ‘_BTWi-fi’ in your list of available networks.
