Good ISP for mobile broadband?

I'm looking to get mobile broadband and was wondering if anyone can suggest a good provider. I'm looking for info on service reception, good speed, cost and general customer service.

It will be mostly used in the North of Scotland.

I currently have a phone with Vodafone but have heard O2 is better in the North for mobile broadband.

Any advice/comments would be appreciated.

Thanks in advance.

I'm with Vodafone as they have good reception in my area. Before you sign up it's always best to check what provider is best in your area!!
