Never had a problem - good pricing, reliable service, and feedback from my customers would suggest that all the text messages are getting through on time. I run kid's classes and text messaging has proven invaluable to send out alerts for cancelled classes / changes etc, even traffic updates. My network not happy with me if I did this by group texts as I flagged up as a spammer on their system, so texting service was the only way to go - would heartily recommend SMS broadcast as a simple solution to this. Emails go astray regularly, but texting has saved us on many occasions!
