That would be a good start.
Share it along with the list of (specific) parts you intend to use.Have you looked through or started with any examples, tutorials, or other SMS projects?
There are a LOT of examples - and different modem modules out there. They work in roughly the same way, but there are subtle differences.
Pls if you have the code for the project do share. I need help. Thank you.
