Manage SMS notification sending via a 4G box or an external service (free for example)
It seems there are two possibilities:
- Via a USB key to have a local SIM, which uses the cellular network (2G / 3G / 4G / 5G)
- Via the internet. Example of a service that allows this via a web API: Tarification SMS en France pour les messages texte | Twilio
