The 3 phone operators in Luz in May 2007 were Optimus, TMN and Vodafone.
The Tapas 9 phone operators were as follows
David Payne 7748 Vodafone UK
Dianne Webster 7790 Orange
Fiona Payne no mobile 2-4 May
Jane Tanner 7808 Telefonica UK
Gerry McCann 7786 Vodafone UK
Kate McCann 7903 EE ltd (TM)
Matthew Oldfield 7771 Vodafone UK
Rachael Oldfield 7771 Vodafone UK
Russell O’Brien 7713 Telefonica UK
So far so good, but this is where the going gets tough. Trying to match up Optimus and TMN with Orange, Telefonica UK, and EE ltd is proving puzzling.
Telefonica is Spanish, and does not in 2015 trade in Portugal, so there must have been a deal in place to run through one of the 3 operators in Portugal, but which one or ones?
At this point in time, we can reasonably assume that a Vodapfone UK mobile would go through the Vodafone, so at least we start with 4 of the 8 people.
We also know that when the caller and the person called are both within Luz and the call goes through two operators, we see double reporting of a single call, once each by the two operators.
Gerry makes 2 calls to Kate on 3 May 2007, and both of these turn up twice in the records. So Kate is not on the same operator as Gerry i.e. she is not going through Vodafone. This is confirmed on 4 May 2007 when David Payne, on Vodafone, is in contact with Kate, not on Vodafone, and the call gets double reported.
Inspector Paulo Dias says that Optimus contacts are marked in orange (the colour) while TMN contacts are in blue. I cannot find anything that states what colour is used for Vodafone.
I also have the problem that I don’t see how one can tell which network a 3rd party is using. I can tell that Gerry is on Vodafone, but when he connects to 2 English numbers he has in common with Kate, which colour is appropriate? Should it be the Vodafone colour that he is on? Should it be Kate’s orange or blue (even assuming I can work out which she is on?)
For the moment, here is a slightly updated graphic of the shared 3rd parties. To match the apparent heaviness of the lines, I have used orange, a lightish blue, and a dark green for Vodafone.
