ZTelco Microwave Internet Service is Faster

We achieve top speeds using the latest innovations in fiber communications utilizing microwave receivers for achieving connectivity without expensive construction. Traveling at the speed of light and in a straight line, our service provides the lowest latency currently available. Scalable bandwidth options up to 10Gbps via microwave are available. We also provide Internet via fiber or T1.

We are a Top-Rated Service Provider

For a few years, we were using ZTelco but only at 2Mbps up and down. In 2019, we needed more speed! Before, they couldn't accommodate. I called on a half dozen other companies. The bigs couldn't provide access at a reasonable cost. Other "line of site" companies could not provide access. Satellite companies had caps on data and upload speed. But this year ZTelco was first able to quickly upgrade us to 10/10 for a small increase on our current contract. Even at this speed they were the best option to upgrade. After their owner saw my first 5 star version of this review he commented (below?) that they "might be able to do better." I called again, and now they've upgraded our equipment and now we've got a very stable, reliable and fast 20 Mbps down and about 94 Mbps up. Their tech support (Alex) also went above and beyond with visits and calls trying to resolve an issue connecting to our cloud backup service, that wasn't even their fault. It's been reliable and fast. Super pleased with the service and support!

When I needed help with my headphones, I called them. Even though it wasn't technically their equipment, they answered the phone immediately and knew just how to fix the problem. Very good customer service and knowledge.

ZTelco did our new phone system for our office. The transition was so easy and we had no down time. Great company to do business with. Very professional and responsive. We have three offices in three different states and our phones work seamlessly with one another.

My company has two business locations/links with ZTelco. So far they've been great! The two links I use with them are wireless point-to-point. Speedtests have been consistent at the rate we pay for. Their maintenance cycle have minimal effect on my business links. They have email notifications and a webpage to announce their maintenance. All professionally ran. I also have VoIP/phone system with ZTelco for both business locations. Phone and email support has been excellent. Quick turn around time and nice, professional people who know their technical skills. I can email them for support or when I need immediate assistance they answer my phone calls right away. That is what is expected and they do it! That's great service! I highly recommend them to anyone.
