Tampnet and ODIDO Netherlands today announced a long-term partnership to share offshore mobile networks in European waters and the Dutch continental shelf. The agreement ensures that more than 100.000 offshore workers and visitors can enjoy mobile connectivity at standard EU roaming rates, just as they were onshore.
Stavanger / Amsterdam, 22. September 2025
Tampnet already operates close to 300.000 square kilometres of mobile LTE coverage in the North Sea, spanning the UK, Danish, and Norwegian continental shelves in addition to the Netherlands. This existing footprint will now be strengthened through the partnership with ODIDO, creating the largest and most integrated offshore mobile network in Europe.
"This partnership means that offshore workers can finally stay connected without worrying about the high roaming costs. For people working weeks at sea, being able to use their phones like at home is more than convenience - it's quality of life", said Elie Hanna, CEO at Tampnet.
Roam Like Home at sea
The new network will appear on devices as "ODIDO@SEA", seamlessly integrated into ODIDO's network.
Roaming partners will be able to recognise the use of this network extension by the end-users and allows them to amend their Welcome SMS for the use on the EU-waters within the Roam Like Home bundle.
"Connectivity is a basic expectations, whether you're in the city or out at sea. By teaming up with Tampnet, we're making sure our customers and partners can work, connect and share from offshore installations and vessels with the same confidence and simplicity they enjoy on land", said Søren Abildgaard, CEO at ODIDO.
Acceleration of Innovation at EU waters
Beyond roaming, the agreement paves the way for advanced mobile services at sea, including:
- Deployment of 5G Standalone and network slicing to support mission-critical services
- Push-To-Talk (PTT/MCX) for public safety and enterprise users
- Collaboration on private 5G networks and edge compute for offshore platforms
As part of the partnership ODIDO will share its offshore sites with Tampnet, handing over operational responsibility while maintaining their mobile services. Customers of KPN and Vodafone Netherlands will also benefit from extended offshore coverage under their existing roaming agreements.
