SIM and eSIM for crew changes
Send a one-time eSIM code with the travel itinerary, so each seafarer has data on the way to the joining port. A new eSIM covers the port calls in each new region.
Short answer: A crew change runs on tight times: flights, a port agent, a launch, and a berth that moves. The one-time code goes out with the travel itinerary, so the seafarer has data in transit and on arrival. A phone without eSIM gets a SIM pack through the port agent, and a new eSIM covers shore leave in each new region.

- Codes with the travel itinerary
- No seafarer names
- A new eSIM for each region
From the airport to the gangway, online.

Before you choose
Short answers to the common questions. The partner agreement sets the final terms.
Does the plan work at sea?
No. The plan works ashore and in port, where there is mobile coverage. At sea, the crew uses the ship Wi-Fi.
Do you need the names of the seafarers?
No. The crew manager buys the codes and assigns them. RoamWorks needs the joining port, the dates, and the number of codes.
What about a phone without eSIM?
The port agent hands out a SIM pack at the joining port, after a phone check. Both formats need an unlocked phone.
Who pays for the data?
The vessel or the company buys the codes at a partner price and assigns them to the crew.
