myFirst Fone R2
$60 under your budget
The most feature-dense sub-$100 kids watch — 4G eSIM video calling, real-time GPS safe zones, an AMOLED screen and a 5MP camera, and the cheapest dedicated model you can buy outright.

■ The catch — co-equal billing, always
There's no full keyboard. Kids reply with voice notes, canned messages and video calls instead of free-typed text — the one thing the ~$300 Garmin's on-device keyboard adds.

Traps — this verdict avoids
Why the myFirst Fone R2 is right for you
It avoids every trap below — and for a kid, under $150, it is the pick because it delivers:
The plan is the real price
Every kids watch with calling and GPS needs a monthly data plan — roughly $5–$25 a month on top of the device. Over two years the plan can cost several times the watch itself.
Battery 'up to' fiction
Manufacturer battery figures assume light use. Heavy LTE, GPS and video calling cut real life by 30–60% — the Fitbit Ace LTE's rated day drops to ~16 hours.
Not everything is on Amazon
Bark, COSMO, Gabb, Pinwheel and Gizmo are carrier- or direct-to-consumer-locked behind a bundled subscription — only 4 of the 10 models sell outright on Amazon (Garmin, Fitbit, TickTalk, myFirst).
Provenance — 7 sources, dated
