What are Ring Alerts?
If the device is expecting a mobile terminated message, and it is registered on the network, when a
message is queued at the gateway, a small free message gets sent to the device saying “Ring”. You could
build your firmware to recognize that serial input to the field application to say “When this happens,
create a session to go to the network and grab whatever message is waiting for me”. This means the
device does not have to constantly ping the network. To receive an SBD ring does not cost anything,
however, the retrieval of data as a follow up will.
