I joined SMS Broadcast as I needed to send a number of SMS's to people about a project go-live weekend. These people were on both Android and IOS phones. Normally we can manage this with using phones directly, but there were too many. The software is all web based, we signed up for 500 texts and paid the £10. Took a few minutes to sign up and very easy. We sent just under 470 messages during the weekend. There were no obvious issues with delivery. The wen interface is a little simple and doesn't look fantastic BUT it does work well enough for us, so I can't complain. It's simple to use, simply paste your message and numbers to send and that's it I can't fault it as it did everything we wanted and needed at a sensible price. We looked at a number of providers but happy we chose SMS Broadcast.
