Any idea how to calculate sector IDs for Vodafone and EE 2G?

Was wondering whether I could get help with this, I've recently been working on 2G and 3G listings on O2 UK in my area but I'd like to work on Vodafone and EE too. The only problem is that I don't know how to calculate sectors for them.

I know O2 tends to be relatively easy and you can even search 2G BTS IDs up in my network (it's "site:[cell ID]" for anyone wondering) but I have no clue about the others.
