no one has priority, the mast sees a phone as a phone, it doesnt check if the number relates to giffgaff, tesco or o2

They do actually
Highest priority...Security and Emergency services
Contract customers
PAYG
VPN including roaming sims
ETA
also the cell can only handle a finite amount of connections at any one time.

what he said
If it all went belly up, joe bloggs might get a "signal" but they wouldnt be able to use it - whereas certain security and corporate users will work just fine.
Priority is def given to certain users - and i'm betting it wouldnt just be when the cell is busy.

System

On that basis, why doesn't the O2 mast let my phone with a 3 sim connect to it?!

Not to mention the fact the network will also control priority to data via both the APN (you'll notice that there are a number of APN's) and further by username.
