UKOnline.net offers three packages of internet access services. You can try out opensurf, pay as you surf and mail. The most popular is Pay as you Surf, as this service is charged when you get online and at a local rate which appears on your phone bill. There will be no set up cost needed. Also provides a mailbox feature with webmail access and spamfilter. The best thing is there will be no need for a BT line. (U.K. only)
