We recently moved our dental practice over to Summit for phone services, and the experience has been excellent from start to finish. The team has been responsive, professional, and incredibly helpful throughout the entire setup process. The transition was smooth, any issues were addressed promptly, and communication was always clear and efficient. Reliable phones and internet are essential for a busy practice like ours, and Summit has delivered exactly that. A special thank you to Michael for his patience and ongoing assistance during the transition. Highly recommend Summit to any business looking for reliable service and great customer support.Read more

As a reseller, we primarily work with Summit’s 4G services and have been very impressed. The plans are affordable, flexible, and well suited to our customers—especially for internet failover solutions. The sales and support teams are responsive and genuinely helpful, which is why we’re proud to partner with Summit Internet. We happily recommend them.Read more

After working with another ISP for several months to deliver a critical internet service for a major international sporting event, we were ultimately advised that the required upgrade was unlikely to be completed prior to event week. This left us facing a significant risk to service delivery. After exhausting all other options (and a few sleepless nights) we came across Summit Internet. From the initial conversation, Allan immediately understood the severity of the situation and quickly engaged his technical delivery team. Michael “Radar” was on site within days to assess and finalise a solution. Despite challenging conditions, including large trees and other obstructions, he worked tirelessly to design and implement an alternative approach. Leveraging an adjacent building, a temporary NBN connection, and a wireless link into the comms room, the solution was delivered within 24 hours of the initial site visit. Not only was the outcome faster than expected, but it was also more cost effective and delivered higher speeds than originally promised by the previous ISP. Over the course of the event, the service handled terabytes of data and supported hundreds of concurrent users without a single speed or performance issue. I cannot thank Summit Internet, particularly Allan and Radar enough for their exceptional service, technical expertise, and commitment to delivering under pressure. Highly recommended.Read more

Summit internet recently set my small business up with a local land line number and a soft phone that runs off an app on my mobile - getting my personal phone number off the internet and being able to distinguish between business and personal calls is a game changer. Whole process took less than a week, and is super cost effective. Highly recommend.Read more
