Published specification
What is true of this model and changes how you fix it
These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.
- Model — Ace LTE (kids watch)
- A children's smartwatch with LTE CELLULAR (calls/messages to approved contacts), GPS location for parents, a speaker and microphone, and motion-based games. So it uniquely (for Fitbit) DOES have cellular and speaker/mic symptoms.
- Cellular plan required
- Its calling/location features need an active Ace LTE cellular plan (a Google/Fitbit subscription) — 'calls or location not working' is often the plan/provisioning, not the watch. Set up and managed by a parent in the companion app.
- Parent-controlled
- Contacts, school time and features are parent-managed in the app; many 'restrictions' are the parental settings working as intended, not faults.
- Backup path
- Carries a cellular backup path for alarm signalling. Backup carries signalling, not bandwidth — so the system can report itself online and monitored while everything that needs broadband fails, and can stay in that state for weeks unnoticed.

Exact questions
Questions that only have an answer for the Fitbit Ace LTE
Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.
My child's Fitbit Ace LTE can't call or be located.+
The Ace LTE's calling and location depend on its LTE cellular plan (a subscription), so first confirm the plan is active and provisioned in the parent app — an expired or unprovisioned plan disables calls and live location. Then check the approved-contacts list and any school-time or bedtime restrictions, which intentionally limit features at set times. It needs cellular or Wi-Fi coverage to connect. Most 'not working' cases are the plan or the parental settings, not a hardware fault.
Structured depth, not empty permutations
Every published record carries a direct answer, scope, ordered fixes, risk notes and sources.
Device and manufacturer hubs share a consistent record system, but each answer carries the relevant controls, fault boundaries, consequences and official support entry point for that platform.
