A SIM card is required even to set the time.
It is more of a child tracking device than an electronic watch.
So if you just want a watch for the child, get something else.

Unfortunately, it is not a GPS watch. It only supports LBS, resulting in the location of the wearer not being accurate even in open spaces. Its position depends exclusively on the mobile network of the provider it is connected to.

Very good for the money, with a lot of features. Great care will be needed when inserting the SIM card, so as not to damage the little metal piece that supports it. According to the instructions (https://manuals.plus/tekkiwear/ab0064-q12-smartwatch-manual), the SIM card must be of a specific type with the PIN disabled. The truth is that until it recognized it, I reinserted it 3-4 times. It does not have GPS functionality and the location is calculated via GSM and wifi. This results in the location being completely inaccurate (several hundred meters away from the actual position).

After many attempts, I inserted the sim, it doesn't recognize it easily, then it asked me to enter the sim code without bringing up a number keypad..... wasted money, it's not worth even 2 euros.

For the money... amazing. For something less than 10 euros, the little one has a smartwatch that theoretically does wonders and has stopped being jealous of her big brother's. win-win

It's a piece of junk!!! Chinese situation!! As soon as I tried to insert my SIM card, the little metal piece that holds the card broke off in my hand!!!!!

After much effort, I learned that the sim card must be pinless for the watch to work, and it works fine for the money so far. Definitely okay for younger children

It doesn't even recognize the sim card, and the sim is placed internally under the battery. Not sideways that seems to open with a screwdriver.

The GPS doesn't work, it shows you that it is 750 meters further away than it actually is, the screen is terrible. It only worked for 2 days.

My father ordered it! First of all, it doesn't have the same button, it doesn't show the weather, it doesn't have the same background, and overall not satisfied at all!

BY FAR the most useless thing I have bought in a long time. As my friend says, it doesn't even have the option to manually set the time, meaning if you don't put an active sim inside it's completely useless.. good for show, but not even remotely functional as a watch.

The sim card does not fit correctly, resulting in occasional loss of connection. Additionally, it does not always accurately display the location

It cannot connect to the mobile phone or the SIM card that I had inserted. There are no instructions, and the ones you find are not valid.

It does not connect to the application, it shows that I am scanning the wrong code, the time cannot be adjusted. Even for its price, it is a very bad product

It doesn't even show the time.
The GPS doesn't work.
The battery doesn't last.
Chinese instructions... wasted money!!!!!!

Terrible product, it's garbage. It was supposed to work for three hours, but it didn't even catch the GPS signal. Chinese watches are terrible

It doesn't work at all without the sim. You can't even set the time. No matter how many sims we tried, it doesn't recognize any.

With 12 euros, don't expect much. The location indicator is unreliable, as it is based solely on mobile phone antennas and not on real GPS, so the location is approximate. The call quality is mediocre, as the child cannot hear very clearly, but their voice can be heard well by the person calling them. The biggest issue with the product is that there are many different models with the same appearance and slightly different capabilities. I ordered 2, and while everything works fine on one, the second one, after returning it once because it wouldn't even turn on, the camera doesn't work (even though it exists) and it doesn't send photos. If you absolutely want precise location, prefer a different watch.

As a game for younger children, it is good. Beyond that, I am still trying to figure out how to pass the time! And its battery does not last

For its price, it is a very good purchase for a first children's watch. The camera is very basic, but the kids are excited about it, lens, etc. The only drawback is that it requires a SIM card even for setting the time.

The description of the watch does not match reality.
The location shown (on the application's map) where the child wearing it is supposed to be is incorrect, it displays it in a different area.
The signal during calls is often weak, settings are frequently lost, and a message appears stating that the device is not connected to a network.

We were never able to use it, the time does not change, the app cannot sync with the watch. We just wasted 15€! Do not buy it

It's a scam.
It doesn't have a good touch screen, it doesn't work...
It takes 5 times to make the motion to work.
It doesn't have accurate location.
It takes distorted photos.
It scratches easily.
It's good for gaming.

terrible product cannot change the time and where ever I look I can't find it bad support and the manual does not explain in details really bad I advise do not buy

For its price, you can't expect something better. However, the sound from the calls is very low and its battery runs out within 2 days of regular use.

Waste of money, not worth even 2 euros and the GPS shows wherever it wants

Terrible functionality, like the first mobile phones with awful color screens and terrible cameras. It only works with a SIM card that has access to the telephone network, it DOES NOT work if it only has internet access.

My daughter was very excited before we got the watch. When we got it, we went to stores to get a sim card to activate three numbers as it said, but it never accepted the card, so she couldn't use the watch.
