How to send sms messages from the list randomly every 20-30 minutes?

Question

SMS

The task is as follows. It is required that sms from a pre-created list, say 150 sms, come to the phone number in random order every 20-30 minutes. What services can do this?

Answer 1

The network is flooded with companies that are engaged in SMS mailings, I think almost every one will be able to provide you with the necessary functionality. Example: easy-sms.ru
Again, you can go in a more interesting and budgetary way - use the services of a company that provides an API (for example, smsc.ru). Copy-paste the code from the documentation (there are many ready-made libraries for every taste). Form an array with numbers, pass it through the randomizer and send SMS. On the server, ask cron to run this business every 20, 30, as many minutes as you like.
