They reckon in a major incident most cities would lose most of their standard mobile coverage in a very short time (cant recall exact figures at this time of night
) Thats why only the very unwise have reliance on mobiles in their emergency and business continuity plans, have a bag of change and a little black book.
Theres loads of anecdotal evidence and accounts after Manchester and London to name just 2 where phone boxes kept going strong, plus BT bring in their emergency kit :thumb2
If anyone gets the chance to via local retail or other organizations, go to an Operation Argus presentation. The local counter terrorism bods do it. Very good :thumb2
