So basically my family already has an isp in Sky broadband and that uses the master socket downstairs in my house. However the broadband itself is in my opinion terrible. Their is an unused phone socket upstairs in my house and was wondering if it is possible if I could get a second isp and broadband for myself using the singular phone socket upstairs? is that possible or would I need certain equipment to get this done or is it not possible with just a phone socket
The phone socket upstairs is irrelevant. If you want a second service you will need to order a brand new service.
okay.. so if I order a new service will they still be able to set it up considering I already have a broadband service
