Explanation of 3G Shutdowns and Their Impact on Our Product

If your device relies on 3G, please read the "Why Does This Matter for You?" and "What You Can Do" sections below to understand how this will affect your service and what steps you need to take.

As many of you may have noticed, telecommunications providers around the world are shutting down their 3G networks. This transition is impacting a wide range of devices and services, including earlier versions of our product that rely on 3G for connectivity. Here's a breakdown of what’s happening and why these shutdowns are important:

What is 3G Shutdown?

3G (third-generation) networks, which were introduced in the early 2000s, enabled mobile devices to access the internet at faster speeds than 2G. However, as technology evolved, 4G (LTE) and 5G networks have taken over, offering far superior data speeds, better reliability, and lower latency.

To meet the increasing demand for faster, more efficient mobile networks, telecom operators are phasing out 3G services. By shutting down 3G, they free up valuable spectrum to expand their 4G and 5G networks, which are more suited to modern needs, such as video streaming, high-speed data transfer, and IoT (Internet of Things) applications.

Why Does This Matter for You?

If your device or an earlier version of our product relies on 3G for connectivity, the 3G shutdowns could lead to a loss of service or reduced performance in areas where 4G or 5G networks are not supported by the product. Once 3G networks are decommissioned in a particular area, devices using 3G may no longer be able to connect to the internet, send data, or perform any network-related functions, or they may experience significantly decreased service quality.

When Will This Happen?

The exact timeline for 3G shutdowns varies by country and region, as each telecom provider manages its own network. Some countries have already completed their 3G phase-out, while others are in the process or planning to do so soon. Major telecom providers in the US, Europe, Australia, and Asia are progressively turning off 3G networks, with many aiming for completion between 2023 and 2025.

Stay informed about global 3G network shutdowns with this resource, keeping in mind that while the information may not be completely precise, it offers valuable insights.

What You Can Do

To continue enjoying uninterrupted service and connectivity, you may need to consider upgrading to a version of our product that supports 4G. By moving to a 4G, you can ensure future-proof connectivity and access to faster, more reliable networks as 3G becomes obsolete.

Usage and Features

How much current does Boat Monitor actually use?

Boat Monitor consumes 1 Ah during a day of sailing and only 24 mAh while your boat is moored. The impact of Boat Monitor on your boat batteries should not be noticeable.

Usage and Features

Will Sentinel Boat Monitor use the power from my battery?

Yes, but very little. With a 100 Ah battery, the Boat Monitor will work for more than 6 months (this is without charging it).

Usage and Features

How will I be alerted in case something happens to my boat?

You will receive a mobile push notification. You should be logged-in to the Sentinel app and have access to WiFi or 3G/4G.

Usage and Features

How precise is the GPS tracking?

GPS Tracking frequency is dynamic - it depends on whether the boat is turning, going straight or not moving at all. The resulting tracks are very detailed as can be seen in this image:

For performance reasons the points may be slightly sparser when displaying the routes on your computer, phone or tablet. You can download the full track using the "Download GPX" button on any route in the web app.

Usage and Features

As boat owner, how do I accept a "GUEST REQUEST"

When a guest scans the QR code and creates an account, you will be sent a guest request, which will allow the guest to see the routes and other information about the boat. You may confirm or reject the guest request by clicking on the "Accept" or "Reject" buttons in the Guests section of the web application or within the application on your mobile device.

Usage and Features

As a "guest user", how do I start using the application?

On your phone or tablet, install the application "Sentinel - your boat, online" which you may download from the App or Play Store (for Android or iOS respectively). Use the app to create an account. Scan the QR code on the front side of the device or provided by the "owner" of the boat.

Upon completion, the wizard will send a "guest request" to the boat owner for confirmation. After the request is accepted you will be able to start using the application.

Troubleshooting

Where can I find the registration and serial number of the device?

The registration code is embedded within the QR code. The serial number (SN) can be found on the front face of the device.

Troubleshooting

Where/How should I position the device to ensure high quality GPS positioning?

The correct device orientation can be found in your device's installation manual. Do not place the device under metal enclosures.

Troubleshooting

I can't login to the application

Please verify that:

  • You are properly connected to internet (WiFi, 3G or 4G)
  • You are using correct credentials (username and password)

Troubleshooting

I am receiving notifications that the boat has moved. Why?

You may have activated the "anchor alarm" functionality, and the Sentinel service is warning you that your boat has moved from its initial position.

Troubleshooting

What happens when the device has insufficient reception (low 3G or 4G signal)?

The device will store the captured data (routes, battery status, alarms, etc) on the device until internet connection is secured. Then, the data will be uploaded and you will be able to see it in the Sentinel apps.

Troubleshooting

My application is not showing fresh boat's data

You may be in an area without mobile Internet coverage (3G or 4G - LTE). The information will appear on your device when strong mobile signal is available.

Troubleshooting

After completing the activation process (registering the device and creating an account) there is still no data visible in the mobile app.

One of the following may be happening:

  • The device has not yet started sending data to the server. In some cases, it may take up to 15 minutes after the device is activated and turned on for the first data point to appear.
  • The device may not be connected to an Internet network.
  • The SIM card is not yet activated. Please contact Sentinel support.
Troubleshooting

The route has been drawn over land.

Due to the sampling frequency it may occur that the route is occasionally (but rarely) drawn over land. If this occurs frequently, please inform the Sentinel technical support using the Report Issue button in the app.

Troubleshooting

Is there customer support available in case I’ll have any add additional questions?

Of course. To access support, it is best that you use the "Report Issue" button in the app. Alternatively, you can write to suport@sentinelmarine.net.

Troubleshooting

The web application is not rendered correctly in Internet Explorer

You may have an outdated browser. Try upgrading your browser to the latest version.

Pricing

What payment options are supported?

We currently support Mastercard, Visa and PayPal.

Pricing

Will taxes be included in my invoice?

Pricing

How do I add a VAT ID number to my account?

We currently do not support adding VAT ID when using our online subscription renewal process. If you are a VAT-exempt business and need to renew a subscription please contact Sentinel support.

Usage and Features

What is the difference between CZone Lite and CZone Unlimited?

The CZone addon allows you to remotely switch selected CZone circuits and receive alerts from the CZone system. Two flavours of the addon are available: Unlimited and Lite

The CZone Unlimited addon allows you to:

  • Receive all alerts generated by the CZone system.
  • Select and switch an unlimited number of CZone circuits. These are excluded from the subscription plan size limit.

The CZone Lite addon allows you to:

  • Receive all alerts generated by the CZone system. Some restrictions apply, see below *.
  • Select and switch** a limited number of CZone circuits. Each selected switch takes one slot in your subscription plan size limit.

* The behaviour of CZone alerts is different between Lite and Unlimited addons. With Unlimited, alerts that are cleared in the CZone system but triggered again will fire a push notification to the Sentinel app automatically. With Lite, alerts need to be cleared manually in the Sentinel app in order to receive new alerts from the CZone system (from same source).

** When using CZone Lite, toggling a circuit in the CZone system will sync to the Sentinel app no later than every 20 minutes. Toggling a switch in the Sentinel app is reflected immediately in the CZone system. With Unlimited, the sync is always immediate.

The CZone addon is not needed if you are only interested in monitoring CZone circuits (without switching and CZone alerts).
