CBdd Cell Broadcast data download for Public Warning System (PWS)
It is possible to make the phones compatible (including feature phones) is to force Cell Broadcast activation and the channel configuration via a small applet on the SIM card.
There is an option though to make CB interative (ICB – Interactive Cell Broadcast) with an addition of a small dedicated applet on the SIM card. This way, delivery reports are available but more importantly, the alert message might be interactive allowing citizens to respond, should they need help, together with sending their location by a single click.
It works like this on all feature phones, smartphones, smartwatches and tablets:
Cell Broadcast :: Cell Info :: SMS-CB :: Difusão Celular :: PWS Public Warning System
