Subscribe to all the messages with mosquitto or open your MQTT client software:

Generate your SMS by sending an SMS to the phone number of the A6/A7 SIM card you will see :
|
|
|
|
```
|
|
home/OpenMQTTGateway/2GtoMQTT {"phone":"+33123456789","date":"2018/04/22,16:17:51+02","message":"Hello OpenMQTTGateway"}
|
|
```
