📲 Forward SMS and calls from any SIM card to Slack.

Built this after I recieved an expensive bill because a service I used only offered two factor authentication via SMS and my phone mysteriously downloaded a couple of megabytes while roaming in Asia. 💰 This seems to happen frequently. Ever since, I leave my local SIM card back home and I'm still able to react to SMS and calls back home using a service such as Rebtel. 😊

I use balena.io to manage my fleet of devices which makes it super easy to manage my fleet:

• Create Balena project.
• Add balena remote and git push balena master.
• Add device to Balena project.
• Set device or fleet enviroment variables: PIN (SIM), SLACK_API_TOKEN and SLACK_CHANNEL.
