Can anyone advise me of a mobile provider that will give me 0800/0845 numbers inc in my contract so I don't get huge bills,.

 

Have you tried using this website to find an alternative cheaper number for the 0800 or 0845 you're ringing? http://www.saynoto0870.com/

Just a thought

 

Giffgaff offer free calls to 0800 >>> http://www.best-payg-deals.co.uk/

 

Don't think there are any providers out there that will offer 0845 for free. Some providers will let you have 0800 free if you drop the first 0

 

Although that will work in real life situations it is highly impractical for me, the phone is used for my company and I am constantly having to call various 0800/0845 numbers so spending the time looking for them all is not a viable option im afraid,

 

Just ring 0800 from a phone box. Have you tried a reverse charge to a 0845?
