You need to ask for a Linked Order Number, (LORN), for a Simultaneuous install, (SIM). That's if they do those for Infinity. A LORN is a different style of number in some way, and if submitted to Openreach with the broadband order then with luck it all gets done at the same time.
Otherwise the Infinity order might not start moving until a few days after the phone line is up and running.
