Why does the Ultimate Broadband Guarantee use sync speed not download speed?

Sync speed and download speed are different:


Sync speed

Download speed

Other names

Access or sync speed

Throughput speed


Can only be controlled and managed by internet provider

Can be managed by users with support from internet provider

Measured in Ultimate Broadband Guarantee





Due to this difference, it’s very important when buying Vodafone Broadband to understand that our Ultimate Broadband Guarantee covers the sync speed, and not the download speed on your devices.

We use sync speed as it’s largely within the control of Openreach

(the line provider) and ourselves to manage any faults and improvements that can be made to the network where you live.
