Since launching Openzone two years ago, BT has set up 4,000 wireless hotspots across the UK at sites such as McDonald's restaurants, British Airways lounges, railway stations and Hilton hotels.
To attract more users, BT is now charging £25 a month for 4,000 minutes of access time (three hours a day) to customers who sign a 12-month contract. Previously, users would pay £10 for 120 minutes, £20 for 300 minutes, and £40 for 900 minutes online.
After 4,000 minutes, if required, users pay 10p a minute up to 4,600 minutes. The maximum monthly charge is capped at £85 - the same as the previous unlimited monthly access time package.
For those not wanting to sign a 12-month contract, BT has introduced a £40 voucher that gives 4,000 minutes within a 30-day period, and the existing 24-hour voucher has been reduced from £15 to £10. The price of the one-hour voucher remains at £6. There is also a pay-as-you-go option that stays at 20p per minute.
BT Wireless Broadband chief executive Chris Clark said, "These changes are in response to both evolving user requirements and the learning we've gleaned to date."
