I hate to blame the victim here, but anyone in the 2020s buying a carrier-branded piece of cellular hardware should have expected this sort of thing.
We already learned this lesson back in the days before the iPhone when phones had carrier logos printed on them and GPS apps cost $5/month.
Apple Watch Kids Mode is what you want. If the watches cost too much grab a used one.
The author complained about the high price in the original review but they didn’t really spend enough. They bought a crappy telecom knockoff of an Apple Watch. You get what you pay for.
They’re not a victim, they’re just being slightly inconvenienced.
Apple watch only works if a parent has an iPhone, and we're both on Android.
