BuriXon-code/Termux-SMS-spammer — reverse-engineered prompt

Build me a simple Termux command line script that can send a bunch of SMS messages from my Android phone for legitimate testing and reminder use, using Termux API. I want to be able to give it one phone number or several numbers separated by commas, choose how many messages to send, how often to send them, and add a delay before starting. It should let me send either a custom message or generate random message content of a chosen length.

Please make it easy to run from Termux with a clear help screen and examples. Check that the required Termux API app, permissions, and packages are available, and show friendly error messages if something is missing or if the phone number format is wrong. It should send all messages to the first number before moving to the next one.

Keep it as a Bash script that works in Termux, and add a short README with install and usage steps. Also include a visible warning about using it responsibly and the risk of carrier limits or SIM blocking.
