Customer Testimonials

"Djibouti Telecom developed a great partnership with SubCom during DARE-1 project implementation. We appreciate their attention to detail and proactive approach to bring our regional cable to life."

Mohamed Ahmed Director Business International Djibouti Telecom, DARE-1 Chair

"Since the implementation of the Svalbard system in 2004, Space Norway has enjoyed a strong and enduring relationship with SubCom. For over 14 years, SubCom has delivered unprecedented support for this unique cable system, providing uninterrupted service during three capacity upgrades and a CLS equipment consolidation and relocation operation, helping to meet Space Norway's current and future growth requirements. We strongly believe in SubCom's project management and engineering teams to deliver upgrades with professionalism and dedication, and when coupled with the long-term support provided by their Global Technical Support Center (GTSC), we benefit from a level of service and commitment that is second to none in the industry."

Jostein Rønneberg CEO of Space Norway

"Following a very successful transition to SubCom in 2017 as the new supplier for Telstra’s subsea maintenance requirements in the South Pacific Marine Maintenance Zone, the team has continued to provide exceptional levels of service, from the finance team right through to the operational team. It is great to have such a high level of engagement and support."

David Copeland Senior Procurement of Telstra

"The collaboration between MainOne and SubCom for the MainOne system was a great success that brought connectivity and economic opportunity along Africa’s west coast. SubCom’s superior technology created a robust and highly-reliable system, and the excellent teamwork and ongoing support we’ve received from everyone at SubCom is again front and center, on our latest MainOne expansion. We couldn’t imagine doing this with any company other than SubCom."

Funke Opeke CEO of MainOne Cable Company

"SubCom provided us with an innovative and flexible solution which included a lifecycle partnership through their remote NOC services and commitment to retain a maintenance vessel in our region."

Simon Fletcher CEO of Interchange

"I’m impressed with SubCom’s quick adaptation to mould flexible solutions that meet market demands and customer needs. Tailoring towards the needs of the future…that’s a key thing for me."

Nigel Bayliff CEO of Aqua Comms

"The SubCom culture fits perfectly with our developer mindset. SubCom found solutions on terms and design to accommodate our requirements and evolutions, during the system design and then during the implementation."

Remi Galasso CEO of Hawaiki

We are very pleased to be working with SubCom to extend our Norwegian sustainable data center and network infrastructure. The quality and experience they have delivered to Norway´s two cables from Andenes to Svalbard above the Arctic Circle makes a very convincing reference to us.
