A resident of Rose Villas (by the main road) has reported ongoing problems with the Orange phone service. Missing calls can be serious if you have responsibility for sick or elderly relatives.
The Ofcom site shows 4 masts in PB, the one on the hill at the golf course is 3, Vodafone has one by the pylons where the footpath crosses the ridge at Charmwood Farm. Orange and O2 have masts down at the farm itself. T-mobile does not seem to have a presence.
