The Critical Services Roaming Network is used by organizations throughout the UK where the loss of mobile data connection is not an option. Used by local authorities, Ambulance Services, Security Services and other mission-critical organizations.


This service works by combining all the four major UK Mobile networks into one, meaning your device will lock onto the best possible signal from any of the four networks. The service has no home network, meaning it will not try and lock on to just one network it will pick the best one for the location you are currently in.

This service is provided by BroadNet Communications Systems Ltd who provide nationwide push to talk communications and dispatch systems for ambulance companies, security services, and other organizations with a range of handheld radios, mobile devices & mobile data terminals available along with a powerful dispatch and tracking system.

BroadNet combined with the Critical Services Network now makes the UK’s most powerful PTT Network far outperforming the Tetra network or single network PTT systems.

We have managed to combine the cost of the BroadNet Licences with a rolling contract for access the Network, this will be one cost that covers everything so you don’t need to worry about mobile phone contracts or topping up data.

The SIM cards will be fixed to BroadNet so you will not be able to use the network for downloading from the internet for instance or tethering to a BroadNet device to gain internet access. You can make telephone calls and the bill will be charged to your account, however the cost would be more than a normal phone call so we suggest you use a normal phone to make normal calls.

Because of the nature of the Critical Services Network, it is not currently available to everyone and only to organizations considered to be of a critical nature by BroadNet Communications Systems Ltd.
