Our devices work with normal mobile network and not with satellite network, so usually devices work approximately 20 miles from the nearest land (with a presumption that the nearest land has mobile base station and consequently mobile coverage). When device looses network coverage the data is stored and uploaded when mobile network connection is restored.
If for some reason the normal operation is not restored (and position of the boat is not visible), even dough the boat is located in the area where the mobile network coverage is confirmed to be normal, please report.
Roaming and local SIM card usage
- Sentinel Boat Monitor devices include a dedicated SIM card for cellular connectivity, managed by Sentinel.
- The service is designed to be operational worldwide with a flat fee for data communication.
- While Sentinel manages roaming to minimize additional charges, devices may experience service limitations or suspension in countries with expensive data plans or those that do not allow permanent roaming.
- If you plan to use your boat in a country where you are concerned about connectivity, please contact support for more detailed information.
- It is not possible to use a local service provider's SIM card in the Sentinel Boat Monitor device.
