What to know before buying

Listing details to confirm

The listing is inconsistent about screen size: the title and detail field say 1.83 Inches, while feature text says 1.75-inch HD screen. It also calls the watch waterproof and claims IP68 in the title, but the details provide only a 1.5 Metres depth figure without clarifying the applicable water-resistance conditions. Confirm the screen and protection specifications for the selected model before purchase. A 4G SIM is not included, and network compatibility is not specified.

Who is it for?

A good fit for

Parents or carers seeking a child’s watch with 4G calls, video chat and location features, and who can provide a compatible SIM.
Families wanting a scheduled classroom mode and an SOS calling option.

Less suited to

Buyers who need a watch that works for 4G calling without arranging a separate SIM.
Anyone requiring a firmly specified screen size or clearly defined water-resistance conditions before buying.

Frequently asked questions

Does the watch include a SIM card?

No. The listing says to use your own 4G SIM card. It does not specify network compatibility.

What screen size does the watch have?

The listed detail field and title give 1.83 Inches, while feature text gives 1.75-inch HD screen. The listing does not resolve this difference.

What does classroom mode do?

The listing says it can be set for up to four time periods and blocks games, messages and incoming calls, leaving the time display and SOS function available.

What location features are listed?

The technical details list GPS+LBS+WiFi, and the feature text claims safety zones with app notifications when a child enters or leaves them.

Is the watch waterproof?

The listing calls it waterproof and claims IP68 in the title, while a detail field lists 1.5 Metres. It does not explain the conditions for that depth claim, so confirm suitability for the intended use.
