Kids smartwatches are a great way to help children stay connected while giving parents peace of mind. Many of these devices offer GPS tracking, calling, messaging, and even fitness tracking. But one question parents often ask is: Do kids smartwatches need a data plan? The answer depends on the features you want and how your child will use the watch.
When a Data Plan is Needed
Your child’s smartwatch will require a data plan if you want:
- Real-Time GPS Tracking: Location updates outside of Wi‑Fi range.
- Two-Way Calling: Making and receiving calls without being connected to a smartphone.
- Text Messaging: Sending and receiving messages independently.
- App Access: Using apps that require internet connectivity.

When a Data Plan is Not Needed
Your child can use a smartwatch without a data plan if it’s designed to work offline or with Bluetooth/Wi‑Fi only. Examples include:
- Fitness trackers like Fitbit Ace 3 or Garmin Vivofit Jr. 3.
- Smartwatches that connect to a parent’s phone via Bluetooth for limited features.
- GPS-only devices with location logging for later syncing via Wi‑Fi.
Pros & Cons of a Data Plan for Kids Smartwatches
Pros:
- Full independence for calling and GPS without a phone.
- Real-time location tracking for safety.
- Access to emergency SOS features anywhere.
Cons:
- Monthly subscription costs (£5–£15 in the UK).
- Battery drains faster with cellular use.
- Risk of overuse or distraction if messaging and apps are available.
Data Plan Cost in the UK
Typical UK data plans for kids smartwatches cost between £5 and £15 per month, depending on the network and whether calls are included. Some watches come with built-in SIM cards tied to a specific provider, while others allow you to choose your own SIM plan.

Final Verdict
If you want real-time GPS tracking, calls, and messaging without relying on a smartphone, you’ll need a smartwatch with a data plan. However, if your main goal is fitness tracking or occasional location checks, a no-data-plan watch is often enough — and it can save you money each month.
