The wild thing about this is that this isn't just a B2B fraud, but regular joes are hit with it as well and regular operators don't care.

My phone got stolen in Naples last year, just as I was about to board my plane. It was 11PM, so when I called my boss from my gf's phone he decided to block the number the next morning as he was in bed already. By the time the SIM was blocked, 10 hours had passed, and thieves had managed to place over 100 hours of very expensive toll calls to numbers in Algeria. It cost the company over 10k, and our operator was not willing to accept any responsibility over it. Admittedly, I turned off the PIN lock because my phone at the time would overheat and restart multiple times a day, but operators really should have lockouts on foreign payphone numbers, especially once they're being placed faster than a human can dial them.

That's terrible!

Rate limits and billing limits should definitely be included, even on personal numbers.

I tend to disable premium services in my billing when available, and/or the provider will mention that they're just not available on my service.

Although (fraudulent) CLI overstamping is still a mess here (Australia, and probably everywhere else) despite attempts to fix it with industry code.

You gave the operator an out. While this shouldn’t prevent remedy, in some cases it will.
