This application was created just for you to take a chance to send someone a thoughtful SMS or a MMS picture to remind them just how awesome they are.

Reading this will prepare you to install and start your brand new Postcards application and get on the road to brightening someone's day.


Things you will need

  • A Skyetel phone and SMS/MMS account. If you don't have one, visit and try it.
    • A Skyetel phone number with SMS/MMS feature enabled
    • Inside your Skyetel account retrieve your API SID and Secret to send messages
  • Super user access to a Linux-based server that does not already host a website
    • This works best on CentOS 7 and newer, but should also work on most Debian-based servers
    • Windows servers are not currently supported
  • A public domain name like that points to your server
  • Your server should have at least 2GB of RAM, and we recommend 4GB if possible.
