We are interested in using Aeris, but our system uses SMS-MT for immediate comminications. Is there a cost if we use SMS-MT via the AerFrame API? Or is the SMS-MT cost only when its from external numbers (ie. Other sims)?
Our other carriers we use dont charge anything for SMS-MT via their API.
Thanks for the question. We do charge a fee for SMS (for specifics about SMS charges please refer to this page).
One of the security features our connectivity service provides is the inability to reach a device on the network directly from another device (e.g. voice or SMS from a handset to a Neo SIM). This prohibits potentially abusive network activity from impacting your IoT devices.
The only way to transmit SMS-MO or -MT with a Neo SIM is through the AerFrame API. The Neo connectivity management portal has a "Send SMS" feature, which invokes AerFrame, so whether you use the portal or access AerFrame directly with your application the API is used to transmit SMS.
