Some of the problems on the mobile networks were the result 
of a protocol to reserve mobile capabilities for the 
emergency services. The police have the authority to switch 
cells to emergency service and then people with specially 
registered SIM cards in their mobile can take priority. 
Presumably, some amount of capacity is also held in reserve 
for these people as well.

Requests from the police on specific SIM numbers on certain 
mobile networks whilst others applied such that you got no 
access to a cell site, others deployed a limit on normal SIM 
cards to limit the access down by 50% so that there was some 
level of service. 

Regards,
Neil.
