Interesting, but GSM isn't the best option for this, someone could eavesdrop on the call with a $15 phone and 3 minutes (GSM encryption has been broken, check out https://security.stackexchange.com/questions/35376/are-phone-calls-on-a-gsm-network-encrypted), get the number and spoof the caller ID (the number) to gain access. Not to mention the 2G sunset taking place in many countries. At least, it should use 3G, but 4G would be better (especially on the EU where 3G will sunset in 2020 before 2G does in 2025). Or you could use LoRa if you don't want to spend $50 on a 4G module.

Thank you for this. As a very new Arduino-ista with lots of ideas (some good, some lame), it is good to see practical examples of what is possible. Seeing a demonstration of how to connect to the sms system has come at exactly the right time for one of my project ideas. This project my not satisfy the expectations of seasoned experts but had value to me.

This is not a project - this is an exercise of purchasing power. Buy a few modules that are made to plug together and ... plug them together. Just call it a demo - but not a project. Very disappointing.
