Watchy4 – Support

Battery life depends on how often the location data is sent (this can be set at intervals of 1-60 minutes), the GPS and GMS signal strength and the length and number of calls. For optimal longevity, we recommend setting a 3-minute interval in the mobile app (LAMAX Tracking).

Location transmission interval
3 minutes
60 minutes

LAMAX WatchY2 battery life
Up to 36 hours
Up to 120 hours

LAMAX GPS Locator battery life
Up to 100 hours
Up to 240 hours

It is also possible to request location at any time using the Live Tracking feature, which will send the location data at 20-second intervals for 3 minutes. When it is finished, the interval automatically reverts back to the previous setting. This feature is power consuming.

Fully charge the battery before using it for the first time. It is not good for the battery if it discharges completely. However it does not adversely affect the battery to charge it in short cycles (if you have to interrupt the process before the battery is fully charged).

Nothing matters to us more than the safety of your child, pet or possessions. That is why we decided to run the service on local servers directly at our European headquarters. Thanks to this, we can ensure the maximum possible level of security over this sensitive data.

Yes. With the LAMAX WatchY2 device, it is necessary to insert a prepaid MicroSIM card and with the LAMAX GPS Locator device, a prepaid NanoSIM card, which you will find in the box. Then all you have to do is add the device in the LAMAX Tracking application.

It depends on the operator. Some offer an associated SIM card, in addition to an existing tariff. With some operators, this is free or a fraction of the price of standard tariffs. With a suitable operator, the watch can be operated from as little as nothing per month. The average data consumption of the LAMAX WatchY2 is 50 MB per month (1-minute interval for sending location data and 10 messages per day) and the LAMAX GPS Locator is even less.

Yes, LAMAX Tracking devices are designed to be worn, and therefore made of completely harmless materials. You do not have to worry about the presence of harmful substances as with other manufacturers, who often use softened plastics for production which contain phthalates dangerous to your health.

For best results, the watch should be held within 20 cm of the child's mouth.

In the event of an emergency, simply hold down the SOS button for three seconds to establish a connection to your SOS contact.

The LAMAX WatchY2 can have 3 numbers set as contacts for the SOS function. These contacts are set in the LAMAX Tracking application. If the first number in the list is unavailable, the watch will automatically dial the second. If the second number is also unavailable, it dials the third.

If a functional SIM card is inserted in the device, you can switch off the device using the "Remote shutdown" function in the LAMAX Tracking mobile app. Otherwise, the device can be switched off by pressing and holding down the button on the side of the watch.

On the home screen of the LAMAX Tracking application, click on "MENU → Monitored areas". You will see a screen with the "Create monitored area" button, if you have not already created one. If you have already created an area, a list of areas and a button for adding a new area will be displayed in the upper right corner. Find the area you want to monitor on the map, select its size and name it. Finally don't forget to save everything on the bottom right using the "Save" button.

If the GPS signal is sufficient, its accuracy is 5-30 metres. Where the GPS signal is weak, or non-existent, the location is determined using the GSM (LBS) network, which is accurate to within 1000 metres or the Wi-Fi network, which is accurate to within 300 metres.

The GPS system is based on satellite technology. The integrated module targets the object using a satellite. The GPS module in the LAMAX device connects to several satellites at once, sometimes more than ten, so as to best determine its position.

GPS has an accuracy of 5-30 m.

Before being fully-functional, a GPS device must first find its approximate location in order to know which satellites to search for. Unassisted GPS therefore takes an average of 1-3 minutes (maximum 12.5 minutes) to first determine its position using satellites. In this case, our integrated AGPS positioning will prove invaluable.

A-GPS- Assisted GPS, reduces the time required to find an approximate location in the GPS system.

In the case of A-GPS, satellite data and approximate device locations are downloaded from a server on the Internet, drastically reducing the time required to find its initial position.

Using this method, GPS positioning in LAMAX devices is fully-functional in less than a minute and we are able to find the location of the device in a much shorter time than devices without A-GPS.

GPS positioning is very accurate, however, it needs open space to function properly.

Under conditions where signal propagation is difficult (e.g. in rooms, under ground garages, tunnels, subways, near tall buildings, in places around radio transmitters, etc.) the device may be less accurate and in extreme cases the GPS signal may drop out completely.

In such a situation, LAMAX Tracking devices are also aided by the signal from the LBS network, i.e. the transmitters of mobile operators or the surrounding Wi-Fi networks.

This positioning method determines the location of your device by scanning the surrounding networks and the signal strength of each transmitter. This data is then used to calculate the approximate position.

It is usually stated that the accuracy of Wi-Fi positioning is in the range of 50-300 m in urban areas.

If the position cannot be determined via Wi-Fi, it connects to the LBS system.

Using transmitters of mobile operators, a special algorithm determines the area where the child is located. The advantage of this is that you’ll always know what area your child is in.

However, this method of positioning is inaccurate and allows for only an approximate location to be determined. This is especially true on the outskirts of cities or in sparsely populated areas, where there is a lower density of BTS stations (mobile signal transmitters).

It is usually stated that the accuracy of LBS positioning is in the range of 50-1000 m in urban areas.

If you move in areas that have no GPS signal and the watch is using LBS or Wi-Fi positioning, the location may be inaccurate. To display the location using only GPS, we recommend disabling Wi-Fi and LBS location in the application (Menu -> Device settings -> About device). The device will then display on the map only the data obtained using GPS (if GPS data is not available, the last position obtained will be displayed).

If the location of your device is not found for a long period of time or is inaccurate even when locating using GPS (GPS icon is displayed on the LAMAX Tracking device), please check whether there is enough free data or credit on the SIM card in your LAMAX Tracking device. When data runs out, most operators will significantly slow down or turn off data transmission, and as a result the location data may be very inaccurate or non-existent. LAMAX Tracking devices require access to the Internet for proper positioning.

No. All accounts on the product servers, including the LAMAX Tracking application, are completely free.

Yes, you can operate up to 20 watches or other LAMAX Tracking devices under one account.

It is possible for several people to monitor several devices.

Example:
Parents have 2 children and a dog and therefore have 2x LAMAX WatchY2 and 1x LAMAX GPS Locator. For both parents to have access, you only need to create one account in the LAMAX Tracking application. All devices will be registered under this account using the ID numbers of individual devices. Both parents can then log in to the LAMAX Tracking app under the same account, giving both access to the same data.

Yes, just make sure the watch is set up correctly. During lesson times, you can set it to "Do not disturb" mode in the LAMAX Tracking application (Menu -> Device settings -> Do not disturb mode "from-to"). In this mode the child cannot play with the watch (scroll through menus, etc.), no one can call the watch and it can't make unwanted sounds which might disturb the lessons. The only thing that remains functional is the SOS function.

So if you set "Do not disturb" mode correctly, there is no reason why a child can’t wear the watch in school or kindergarten. And if the teacher has a problem with it, just explain this feature to them.

Place two LAMAX WatchY2s next to each other, hold your finger on the "Friends" icon for at least 3 seconds and the LAMAX WatchY2 will exchange contact details and can then call each other.

This function only works between LAMAX Watchy2 devices and only two devices can be connected in this way. Pairing can only be done successfully in the open air.

The correct SIM card for the LAMAX WatchY2 is: MicroSIM with dimensions 15.0 × 12.0 × 0.76 mm and for the LAMAX GPS Locator: NanoSIM with dimensions 8.8 x 12.3 x 0.76 mm.

You only need to insert a SIM card into the watch.

You can use any prepaid card for the LAMAX Tracking device or mobile tariff, which include at least 30 MB of data per month. Free or paid minutes are entirely at your own discretion.

LAMAX Tracking devices use mobile data transmission technology (communication with the server) to send information about the GPS position of your child, pet or monitored items, use voice messages (LAMAX WatchY2 only) and change the settings of the LAMAX Tracking device in the LAMAX Tracking application. If you insert a SIM card without an Internet connection, you will only be able to make calls with the LAMAX Tracking device.

It must support GPRS (2G). This is because sending location data, voice messages or adjusting the device settings from the application do not require large amounts of data plus, it provides the best possible battery life and widest coverage. The LTE and 3G signals are not available in all places but wherever you can make a call, a GPRS (2G) internet connection is also available.

Yes, it only depends on your tariff and your SIM card settings. It is necessary to have roaming activated with your operator.

First, check that all numbers have been entered with the international prefix in the LAMAX Tracking application, or contact your mobile operator to find out if you have activated roaming and verify that all the criteria for using the SIM card abroad are met.

The pedometer must be turned on/enabled in the LAMAX Tracking application in this way (Menu → Fitness → "Gear" Pedometer settings). The measurement interval must be set first. This is the time range during which the pedometer will be turned on. Furthermore, for the correct measurement of steps, it is necessary to fill in the length of the step, and for measuring calories, the weight of the user of the LAMAX Tracking device.

The measurement of the built-in pedometer cannot be compared with professional meters, so only use this data as a guide. Turning on the pedometer increases battery consumption.

1. Fully charge the watch. Use only the supplied cable and a 5 V / 1 A adapter — a stronger charger can damage the device.
2. Insert the SIM card — MicroSIM for WatchY2/3, NanoSIM for the GPS Locator. The SIM must have the PIN disabled and an active data plan (30 MB per month is enough). Test the SIM in a regular phone first to make sure it works.
3. Turn on the watch using the button on the side.
4. Download the LAMAX Tracking app (see the App Store / Google Play links above) and sign up with your e‑mail. The verification code will arrive in your inbox.
5. Add the watch to the app using the 10‑digit device ID (see the “Where do I find the device ID?” answer below).
6. Complete the setup wizard — set the administrator phone number and the contacts the watch is allowed to call.

Do you have WatchY4? It uses the newer LAMAX Connect app and pairs via QR code — see the WatchY4 FAQ and the WatchY4 Academy.

The most common causes:

• Typo in the e‑mail address — double‑check that the address is correct; the verification code is sent there.
• Code went to spam — check your Spam / Bulk folders.
• Weak connection on the phone — make sure the phone has a working internet connection.
• Outdated app — update LAMAX Tracking to the latest version.

If the problem persists, try registering with a different e‑mail address or reach out to us in the chat.

• Check that the e‑mail address entered during registration is spelled correctly — the code is sent to exactly that address.
• Look in your Spam and Bulk folders.
• The app shows a countdown — wait for it to finish and request the code again.
• If the code doesn't arrive the second time either, try a different inbox (e.g. Gmail instead of a corporate address — corporate mail servers sometimes block automated messages).

To add the device you need the 10‑digit device ID. You can find it:

• On the silver sticker on the packaging.
• On devices with a display, also directly in the watch menu under the APP & ID icon.

In the app, choose Add device and enter the ID. If the field doesn't accept the number, check that you've entered it without spaces and in full 10‑digit length.

This message means the watch is already registered under a different account — typically when:

• you bought the watch second‑hand and the previous owner did not delete it from their app, or
• you previously created another account that you no longer use.

How to solve it:

• If it's your old account, log in (use the password‑reset feature) and either use the watch there or remove it from that account.
• If the watch was bought second‑hand, ask the seller to remove it from their app.
• If neither option is possible, contact our support in the chat with proof of purchase and the device ID on the sticker — we can then release the device to your account.

The watch can't enter a PIN code — a SIM with an active PIN therefore won't log into the mobile network and the watch will stay offline.

To disable the PIN, put the SIM into a regular phone:

• Android: Settings → Security → SIM card lock → turn off “Lock SIM card”.
• iPhone: Settings → Mobile Data → SIM PIN → turn off.

Then put the SIM back into the watch. Also make sure the SIM has an active data plan — without data the watch cannot send location or messages.

For WatchY2/3 use MicroSIM (15.0 × 12.0 × 0.76 mm), for the GPS Locator use NanoSIM (8.8 × 12.3 × 0.76 mm). Before inserting, make sure the SIM has the PIN disabled and an active data plan.

Detailed instructions for opening the SIM slot are in the quick start guide of your specific model — see the manuals above on this page.

WatchY4 uses NanoSIM and the slot is opened with the included tool — the exact procedure is in the WatchY4 FAQ.

The watch only calls numbers that are stored in the app — this is a safety measure for the child. Check that:

• the number the child is calling is added in the contacts in the LAMAX Tracking app;
• the SIM in the watch has enough credit or free minutes (check with your operator);
• the watch has signal (signal‑strength icon on the display);
• the numbers are entered in the correct format — for use abroad include the international prefix (e.g. +420…).

The watch only accepts calls from numbers stored in the app — a call from an unknown number is rejected by the watch (the caller hears a busy tone).

Also check:

• Do not Disturb is not active (e.g. during school hours) — in this mode the watch does not accept calls; only the SOS button works.
• The watch is turned on, has signal, and the SIM has credit.

Contacts are managed in the LAMAX Tracking app under the device settings — open the device, go to Menu → Contacts and add each name and number one by one.

The administrator phone number (the parent's main number) is set in Menu → Device settings → Administrator phone number. On the WatchY2 you can set up to three SOS contacts, which the watch dials in sequence if the first one is unreachable.

Voice messages (WatchY2) are sent over the internet, so the watch needs a working data connection:

• Check that the SIM has an unused data plan — most operators throttle or turn off data once the plan is exhausted.
• Make sure the watch has signal.
• Update the app to the latest version.

If voice messages still don't go through, try restarting the watch by pressing and holding the side button.

• Use only the supplied charging cable and an adapter with an output of 5 V / 1 A — stronger fast‑chargers can damage the device.
• Fully charge the battery before first use.
• Short charging cycles are not a problem — you can interrupt charging at any time.

• Try a different adapter (5 V / 1 A) and a different socket or USB port.
• Use the original cable — check that it isn't damaged.
• Gently clean the charging contacts on the watch and on the cable with a dry cloth.
• If the battery is fully discharged, leave the watch on the charger for at least 30 minutes — the display may take a while to wake up.
• If the watch still doesn't charge, contact us in the chat or file a warranty claim (see the last question below).

• With a working SIM inserted, the watch is turned off from the app: Remote shutdown — a safety measure so a child can't switch it off with the button.
• Without a SIM, hold down the button on the side of the watch to turn it off.
• Turn it back on the same way: press and hold the side button.

We recommend restarting the watch whenever the signal takes a long time to load or the device behaves unusually.

• Put the watch on the charger for 30 minutes — an unresponsive watch often just has a fully drained battery.
• Try to turn it off and on from the app (Remote shutdown).
• If the watch still doesn't react, contact our support in the chat or file a warranty claim.

• Warranty defects should be handled through the Returns and complaints page. We're also happy to help in the chat (Jana) or on the phone +420 352 201 423.
• Mechanical damage (a display broken by a fall, cracked glass) is not usually covered by the warranty. For details about a paid repair or replacement, contact us in the chat — we'll put you in touch with the service department.
