The UHF licence free bands and 900MHz Licenced phone bands are different in the USA and Europe.
It's not my opinion. It's fact.
Also the low band FRS USA and low band UHF licence free band for 446MHz Europe are different.
Lower band Licence Free UHF SRD (door bells, keyfobs, outdoor temp sensors, 2.4GHz Video sender remote reverse channels) are different in USA and Europe.
Most of the world uses the same allocations as European (I'm NOT meaning EU). The USA likes to set different standards and ignore the ITU.
But now people buy online.
See ISM band "Licence Free". It's actually PRE-LICENSED as you can't just do anything in each band. Equipment MUST have the appropriate certicfication, FCC, ETSI, CE etc in each telecommunications regulated area.
Also computer security is more complex. This Amazon system is a UHF mesh network in parallel to the regular networks. It's absolutely NOTHING like Apple or Android find your device. Read up on how those actually work.
I actually DO know what I'm writing about as I'm a qualified RF communications Engineer and and till recently worked in computer security and previously acting head of R&D in one telecom company, R&D Director in an other and in charge of R&D for an ISP that used licenced and ISM band microwave links as well as two way satellite and fibre dsl.
I've quoted a reasonable source too.
Most so called smart devices are a way to monetise your behaviour. The security, privacy and reliability track record of IoT like Ring and Nest is abysmal. Companies lose interest and the gear is bricked. Sidewalk is the most ambitious and arrogant IoT system yet as it uses a separate (mesh) network of diverse devices each with an Internet connection per user. It is a disaster for privacy.
The advice from reputable security experts is simply to never connect so called smart devices to the internet. Do not buy any that rely on the seller's server to operate.
It's perfectly possible to have a gadget that only YOU can access over the Internet and is secure. That's not true for Ring or Nest. Also better to use a TV streaming stick or laptop or tablet to TV for streaming than connect a TV direct to the internet. Multiple companies harvest the TV set activity (inc tuner channels, discs played via HDMI, times et, everything possible and some the sounds in the room).

Unlike Virgin Media and Eircom routers, that is absolutely true. However there are other problems.
They keep emphasising the low data usage, but are coy on who gets it and also about system misuse.
