SkyUser - Potential ADSL Line Speed Calculator
This checker queries SamKnows database for information about your telephone exchange, and then shows your estimated ADSL broadband line speed for your new ISP, based on figures from the BT database. The actual speed indicated at the end of this test may not be a true reflection of the actual speed attainable on your telephone line.
To find out your potential ADSL line speed, please input your Phone number with a space after the STD code, ie 01234 5678901
