The brand specializes in producing smartwatches for children. All product designing and production are taken care of in-house.

Their product line includes 4G smartwatches, game smartwatches, and kids’ toy phones. Their smartwatches are available in a wide array of designs and colors. They offer a mix of budget-friendly and premium watches with prices ranging from $69 to $199.

Who is the PTHTECHUS 4G Smart Watch For?

If you are a parent or a guardian, the smartwatch can help you communicate and track your kids. You can keep an eye on young kids without getting a phone.

The smartwatch is a capable and safer alternative to a smartphone. For example, the device supports 2-way voice and video calling. You can also send 15-second long voice messages.

Using the app, you can add phone numbers to contact the watch. This way, you control who your kids talk to and vice versa.

With the simple press of a button, your child can send out an SOS alert. You can choose multiple contacts to be notified in case of an emergency.

The watch can be fun for your kid as they can listen to music or play educational games. Again, you can control how long your kid can use the watch.

So, overall the smartwatch is for concerned parents looking out for their kids. It is a safer way to introduce technology to young kids.

5 Important Factors we Tested the Product on

Now that we know the benefits of the smartwatch, let us understand its performance. When putting together the PTHTECHUS 4G review, we considered factors like design, battery, and features. Here are our findings.

1. Design


The watch is on the bigger side, with dimensions of 2.36 x 1.57 x 0.39 inches. It weighs about 1.76 ounces. Wearing the smartwatch is not uncomfortable, but using the lighter strap would be ideal.

If the size is not an issue, you can use the replacement strap that comes with the box. The other items you will receive in the box are the charging cable, screwdriver, SIM, card pin, and manual.

The charging cable is pretty small. Charging the smartwatch can be somewhat of a hassle. The instruction manuals also need to be more descriptive.

The PTHTECHUS smartwatch has, at the utmost, a decent design considering its price point.

2. Battery

The smartwatch comes with a rechargeable lithium-ion battery. It takes about 2 to 3 hours to get a full charge. The standby time of the battery is 4 to 6 days.

The battery capacity is highly dependent on how the smartwatch is used. If you have GPS enabled, the tracking frequency has a shorter interval, or your kids listen to music, the battery can drain quicker, lasting only a few hours.

If the smartwatch is used to get manual location updates or for voice calls, the battery can last a day before recharging.

To improve battery life, you can use settings like night power saving, clear tasks, or schedule reboot or shutdown through the app.

Again, the battery is decent at best, with it needing to be charged daily.

3. Usability


You will receive a Speedtalk SIM with your package. You will have to activate it through the carrier’s website.

You then need to install the SIM. Ensure the smartwatch is shut down before this step. Remove the screws at the side of the watch. Next, insert the SIM, push it downwards with the help of the screwdriver, and reattach the screws.

Turn the watch on and check the network. You can test if the SIM is active by calling through the smartphone’s dial section.

You can customize, track and manage the PTHTECHUS smartwatch using the SeTracker app. You must register an account on the app. Be mindful of the language and region you select during registration.

Next, you must add the smartwatch to the app. For this, navigate to your profile, select ‘device list,’ and then ‘add device.’ Next, scan the QR code on the back of the smartwatch. Add a custom name to the device and tap done.

Now you can perform tasks like adding contacts through the app. You can add up to 15 contacts which will be automatically synced with the watch.

Both the watch and the app could do with some UI and performance improvements. The setup process is straightforward, but it could be easier with clearer instructions.

4. Features

The PTHTECHUS smartwatch offers a host of features. The most important one is the ability to communicate with your kids through chat, voice, and video.

It has an SOS button. Long pressing the button will send an alert to the added contacts. In the SeTracker app, you can add up to three contacts to be notified in case of emergencies.

Your child can listen to music using the watch. You must store the files in the .mp3 format under the My Music folder.

You can download apps using the WiFi connection. For example, you can download apps like the calculator or Google Translate. But ensure you do not download multiple apps, as it could affect watch performance, memory, and battery.

You can set up up to three alarms to remind your kid about their schedule. You can encourage them to be more active by setting up goals for the pedometer.

You can put the watch to sleep from 15 seconds to 30 minutes using the app. You can also set the device to classroom mode, which essentially acts like do not disturb mode.

Overall the smartwatch offers a full suite of communication, safety, and entertainment features.

5. Performance


You can track the smartwatch’s location through the app’s Map section. You turn the GPS feature on or off. You can set the tracking frequency to 10 minutes or an hour or choose to obtain the location manually.

You can also set safe zones in a circular range of 200 to 2000 m.

These are good location features to have, but the watch’s performance is inconsistent. The accuracy could be off by quite a few feet. This is a concern that I see in many customer reviews as well.

So, if you specifically need location updates on your kids, I suggest you look for other GPS-enabled trackers.

In terms of alerts, you can enable SMS alerts for low battery and SOS. You can add a contact of your choice.

You can customize the watch features like brightness, ringer, alarm, and media volume under the app’s settings section. The watch supports multiple languages.

Apart from location details, the device showed good performance considering its price.

What Sets the PTHTECHUS 4G Smart Watch Apart from its Competitors?

You can make group video calls using the smartwatch. These 2-way calls can be restricted to homegroup contacts.

You can have control over who can contact the smartwatch. In the app, find the Reject Unknown Calls feature. This will ensure that only the 15 contacts saved on the app can call the device. If the watch receives calls from unknown contacts, you will get an alert for the same.

You can find the device using the Find Watch feature if you or your child misplaces the smartwatch. Activating the feature will play a sound on the watch. The device will ring and display a message saying, ‘I am here.’

Another distinguishing feature of the smartwatch is that you can set the SIM APN. You can then remotely restart the device using a text command. Restarting helps in situations when the device is facing network issues.
