Frequently Asked Questions

HOW DO I USE CRUISE+ (eSIM CONNECTIVITY)?
How does it work at Sea and on Land?
  • A SIM, unlocked eSIM capable device is required to use Cruise+.
  • Download our eSIM partner app.
  • Choose your cruise plan based on itinerary.
  • Before boarding your cruise, while still connected to Wi-Fi, install and activate eSIM.
  • Cruise+ service is available once the cruise ship reaches international waters. While on land, your Cruise+ package will work like any other eSIM.
  • Use your messaging apps as normal to make and receive calls, texts, and use data services for web browsing, email, social media, secured banking, streaming and maps.
  • While at sea, your phone will say “Cellular at Sea” or “901” to indicate service is available, be sure “Airplane Mode” is OFF.
  • Data is transmitted over satellite from ship to land. While on land, your Cruise+ package will work like any other eSIM.

Our service operates over a satellite connection. Once your ship is in international waters, the Cellular at Sea network turns on and you will automatically connect to it. Please note that cruise ship roaming rates will apply. Our service will be available while sailing in international waters. Once your ship approaches land again, our service is turned off and the mobile device will pick up local service. If you are able to pick up local service in the port areas, you may be charged a different rate by your carrier than the Cruise Ship Roaming rate. Contact your carrier for pricing and details.

If your cellular carrier has a roaming agreement with Cellular at Sea, your device will automatically connect to our network, when our network turns on, with no additional effort from you.  You will know you are on our network when you see one of the following displayed on your mobile device: “cellularatsea,” “wmsatsea,” “NOR-18,” or “901-18.”  If you are at sea and do not have network connectivity, 1) ensure roaming is enabled on your network settings on your device, 2) power cycle your mobile device, 3) perform a manual search for the Cellular At Sea network from the network settings on your device, or 4) contact your carrier to confirm you have international roaming enabled on your service plan and device.

Simply dial “1” plus the area code and number to call anywhere in North America. Dial “+” along with the country code and number to call non-US destinations. Dialing the + differs per phone model (hold 0 key or find symbol key on smartphones).

Cellular at Sea recommends the following to avoid unwanted roaming charges:
  • Closing out apps not in use
  • Turning off auto-updates on apps:
Apple Devices Android Devices
  • Go to Settings
  • Tap App Store
  • Turn off App Updates
  • Open Google Play Store app
  • Select Menu
  • Select Settings
  • Select Auto-update Apps
  • Select Don’t auto-update apps, and select Done
  • Turning off location services:
Apple Devices Android Devices
  • Open Settings
  • Click Privacy & Security
  • Toggle off location services
  • Open phone settings
  • Under “Personal,” > location access
  • At the top of the screen, turn Access to my location off
  • Manually fetching email (turning off auto fetch)
Apple Devices Android Devices
  • Go to Settings > Mail > tap accounts
  • Tap fetch new data
  • Set to Manual
  • Close the email app > open settings
  • Under “Personal,” touch Accounts
  • In the top right corner, touch More
  • Uncheck Auto-sync data

For precise rates you will pay onboard, please contact your carrier to confirm their Cruise Ship Roaming Rates for voice calls, texting, and/or data usage.

Your cellular carrier handles all billing. They will bill you for any charges incurred while onboard a ship on your next monthly cell phone bill. There are no additional charges or billing from Cellular at Sea or the cruise lines.

In some cases, a mobile device left on, but not used, may incur charges. If a voice call is received but not answered, and the caller leaves a voicemail, you may receive a charge for the voice call. If a text message comes through and the mobile device is left on, you may be charged for a received text message. Please note that devices (iOS, Android, and others) are constantly looking for data connections to perform updates and other synchronization steps. Therefore, it is highly possible that if you leave your wireless device on, you will incur data charges. Please contact your carrier for more information on charges.

Any questions or issues regarding billing must be handled solely through your carrier. Cellular at Sea has no involvement with retail charges applied to the monthly bill by your cellular carrier. Your cellular carrier is the only entity with the ability to make any necessary adjustments to your bill.

Cellular at Sea is available via affordable cruise plans from several wireless carriers including AT&T and Verizon. Please check with your cellular carrier for their specific cruise ship product offerings.

Please contact your carrier to confirm this and your specific pricing details.

Cellular at Sea may support US and International prepaid cell phones with our service.  Please confirm with your carrier.

Cellular at Sea data speeds support web browsing, social media/chat apps, and checking e-mail. Actual data speeds can vary depending on which network technology (3G, 4G LTE, or other) your wireless carrier supports, the network onboard the vessel, and satellite connectivity.

Provided that Cellular at Sea has a roaming agreement with your cellular carrier for cellular data service, you will be able to use our network to access cellular data services (e.g., internet access, e-mail, and web browsing) with your data-capable device. Data roaming rates also apply. Please check with your carrier to determine rates they will charge you.
