My dashboard shows that an SMS originated from the SIM card was delivered, but I never got the message (I am testing to send SMSs to my phone). Any idea what I am doing wrong or what's going on? Below is the screenshot.
Thanks for your question. As I'm sure you're aware, the Neo connectivity service is built from the ground-up for the unique needs of M2M / IoT devices. One of the security features the service provides is protection from devices (including handsets) that aren't on the Neo network. Communication to and from those devices requires our AerFrame API.
Please refer to this post from a developer who went through the same process you're going through. Please refer to our AerFrame tutorial to learn more about sending and receiving SMS with Neo.
