SMS (short message service) is a text messaging service component of most telephone, Internet, and mobile device systems.
SMS is required in many IoT (M2M) use cases. Sometimes it's when the device has no data and sometimes it's when we need to wake up the device.
There are two types of SMS in telecom:
MT SMS or incoming SMS to allow the device to receive an SMS - traditionally it's needed to wake up the device or to check the device status.
MO SMS or outgoing SMS to allow the device to send an SMS. Sometimes, it's for the device to send events/telemetria without the need of data connection.
In both cases we don't need the SIM to have a “real number“. The monogoto approach is more secure and cheaper. When the device needs to receive an SMS, send an MT SMS with monogoto API’s. When the device needs to send an SMS, usually it should arrive to the customer backend rather than a “real number“. Monogoto can make sure that the SMS will be sent to the customer backend without any extra SMS termination costs and with enhanced security.
