Then the netizens got curious and many really called these numbers to verify.
As it turned out, except for the "13777777777" which belonged to a corporation and was reachable, the other numbers were either turned off or nonexistent...
But were they really nonexistent?
"A telecom industry boss once told me their operating system sets up special screening mechanisms for these numbers. Users who aren't on a whitelist basically can't get through; this applies to spam calls too."
Ruan Jingwei chuckled, "For different users, they have flexible screening methods. Among them are government officials, VIP users, and such. I don't need to explain it, you probably get the idea."
Zhou Wang smacked his lips at this and wanted one of these special numbers even more.
After all, he received quite a few junk calls now, but he couldn't block all of them because some were useful. He really needed someone to screen them flexibly...
