After trying multiple SMS gateway solutions, I kept running into the same problem. The reporting.
Messages would show as "sent" when they hadn't actually been delivered. Other times they'd sit in a pending status with no clear explanation of what was happening.
As someone who relies on SMS every day for my own business, it was frustrating. I wanted a platform that was simple, reliable and affordable. A platform that gives accurate reporting, uses your own mobile number and simply works.
