I don’t know whether it’s possible with modern networks, but it was basically impossible to DDoS a tower with SMSs. Either the tower was unavailable at all times even without text messages, or SMSs never caused a problem. You couldn’t even send many text messages at once, it took a while to send say 50 SMSs, like minutes. I know that the tech stack is different nowadays, but it really depends on prioritisation, which I don’t know much about.
