What do our customers say about us?

  • “I've worked with a handful of different IoT companies. Everything always seemed great at first, but it would end up turning into a nightmare. Constant outages, updates, and patches were such a headache for us and especially our customers. I’d get calls all the time from people asking what was wrong with their data plan, and I’d have to go through all the settings again. With Simplex, it’s just like the name says: It’s simple. It just works. I know with confidence that if someone calls about an issue, it’s a user issue. I’ve never had a problem with Simplex. Their support is all in the U.S., and I've always been able to get a hold of someone within minutes. There aren’t many companies like this left. Truly a great company to work with.”
