Its not just in US, it happens in every country. SMS is the main way these links are distributed. So much so that in Sri Lanka, gov planned to add a centralized SMS firewall.
I periodically wonder how quickly this would end if the costs shifted to the telcos who currently see it as a profit center. Imagine if reporting a message got you an immediate $1 credit and they had to recover it from the network which originated the spam: how quickly would they be able to turn on egress filtering?
I think about that every time I just a call with a forged number. I remember when VoIP was coming on the market and people were warning about spoofing but telco executives apparently just blew that off because it’d slow sales.
About 7-8 years ago in France you’d get regular phone calls from actual humans running the same scam about a DHL or whatever packaging requiring duties to be paid. Plus the same SMS scams.
Americans are lucky in they usually don’t have to buy from abroad and when they do, rarely is tax/duty payment required from the recipient (unlike many other parts of the world).
In Germany we get those phishing SMS too, but I think the US is probably worse off, as they get way more phishing calls (which I think are more effective) as scammers in Nigeria or India usually don't speak German or French...
In 2019, when I landed in Hamburg, I got a scam SMS before the "Welcome to germany"-SMS. IOW, the scammers managed to consume the "new arrival" event somehow, and send out their own scam. Tells a lot about how much the telcos actually care / are a part of these scams.
RCS messaging being adopted on Android has meant that I now get added to spam group chats called "USPS" by some criminals impersonating the post office.

Google messages have a good spam filter than can filter in real time them, but I have seen some get though for a small period of time.
