Has vodafone got a good 3G signal?

I live in Inverness (Scotland) and i have an iphone 5. I'm yet to register with a network and i know three doesnnt work at my house. The only option (signal) is to go on vodafone. Do they have a good 3G signal and if so is it fast? An answer is very much appreciated!

Vodafone does have good 3G coverage in most places within the UK.

Check out the Vodafone coverage checker here and you can input your postcode for a more detailed view of the coverage in your area.

A networks signal always varies from one area to another, go onto the vodafone website, and there's a section where you can enter your postcode and check the strengh of the networks coverage in your area. You can do this on all the different networks websites.

Try Ofcom sitefinder- this lets you zoom in on the actual map and you can see who owns a particular mast and whether it is 2g or 3g.

The mobile phone websites are very 'optimistic' sometimes.
