Contact your land-line or mobile service provider. There are international calling options you can place onto your account that remove per-minute fees placed on your calls. This is an exceptional option if you envision calling the UK or any other country often (such as for business).
Dial the London number collect. Use a collect calling service, than dial in the phone number. This sends the service bill to the phone number you are calling, not to your own landline or mobile account. When placing the phone call, you must say your name and a brief message. The name and message is then played for the individual in the UK. The person then has the option to accept your call.
Connect a VoIP receiver to your high-speed Internet connection. VoIP is an Internet-based telephone service that allows you to avoid using expensive landline services. Many VoIP services include free international calling options, giving you the ability to call London without any limitation on your minutes.
