The quick answer.
Smartwatchphone C100 4G GPS Kids Smartwatch (Black) is a connected kids smartwatch watch with case dimensions 40 × 48 mm body · 11 mm thick at €109.95. We recommend it for families who want calls, video calls, location features and parent-managed app controls on a child’s wrist, and are ready to manage a SIM plan and privacy settings.
Why it belongs on the shortlist.
The C100 brings calls, video calls, chat and SMS together with GPS / Wi-Fi / LBS location features, geofencing and a 30-day route history, according to Smartwatchphone. The seller also lists approved contacts, class mode, an SOS button, app controls and a 2 MP camera. For a family looking for several ways to stay in touch, it is an unusually feature-rich package for a child’s wrist. Smartwatchphone places the intended age at 8 and up and lists a 13–24 cm wrist range.
A connected family watch, not just a timepiece.
The C100 is built around communication: Smartwatchphone lists 4G calls, video calls, chat and SMS, plus Wi-Fi use at home. The parent app can manage approved contacts, app access and class mode. That is a useful mix for families who want more than an SOS button, while the choice of apps means it is worth setting expectations together before handing it to a child.
Location tools are useful, but they are not a guarantee.
Smartwatchphone lists GPS, Wi-Fi and LBS location, geofencing and a 30-day route history. Those options provide several ways to check a location, but the product page does not publish accuracy tolerances or a service guarantee. Treat the app as an additional way to stay connected rather than a substitute for normal supervision.
The privacy settings deserve a family conversation.
The C100 page lists remote listening, camera access and apps including WhatsApp, Instagram and Facebook, with parent controls for blocking applications. Some families will value that flexibility; others may prefer a more limited device. Decide which features should be enabled, explain how they work and review the controls as the child gets older.
Confirm size, battery expectations and water limits.
The seller lists a 40 × 48 mm body, 11 mm thickness, 52 g weight and 13–24 cm wrist range. The 730 mAh battery is estimated at one to three days, so actual runtime will depend on calls, location updates and signal conditions. Smartwatchphone lists IP65 and says the watch is for splashes, rain and hand washing, not showers or swimming.

Before you choose
This is a connected device, so cellular functions require a compatible Nano-SIM and a mobile plan; include that recurring service in the cost. The seller lists remote listening, camera access and third-party apps such as WhatsApp, so families should review those controls and agree on privacy expectations before enabling them. GPS, Wi-Fi and LBS are listed as location methods, but no accuracy guarantee is published. At 40 × 48 mm and 52 g it is substantial for a child, and IP65 is not a swimming or shower rating.
Who it suits.
Families who want calls, video calls, location features and parent-managed app controls on a child’s wrist, and are ready to manage a SIM plan and privacy settings.
When to choose something else.
Choose a simpler contact-only watch if you want fewer apps and connected features, or a higher water rating if swimming is part of the routine.
Warranty, returns and ownership.
Smartwatchphone lists a one-year warranty and a 14-day return period for complete items in perfect condition. Cellular functions need compatible mobile service; check the current regional warranty and return terms before ordering.
