Is it possible to send sms from a vending machine?

Question

Arduino

Hello, can someone come across?
There is a snow machine. I would like it to send SMS to the phone if someone bought a chocolate bar or water (yes, any product)
Will arduino help me with this?

Answer 1

For example:
Via GPRS modem. In which a regular SIM card is inserted.
There are such modules for Arduino. Personally, I have several of them - they exist and work, checked.
Another way is through the Internet. Using the services of a specialized service.
For example, SmsC.ru
How to do this you already asked How to put data on a remote server by URL using arduino?

Answer 2

It is possible, under SIM800L there are ready-made libraries for sending SMS with confirmation or e-mail.
I am currently doing a similar project.
