What kind of scam is broadband sending 3000?

Running broadband to 3000 is to attract many members with high-tech job advertisements. According to relevant information, broadband at home costs 3000 yuan a day. A fraud gang recruited several members under the banner of high-paying job advertisements. They opened broadband and installed telephones in rental houses to provide technical support for fraud gangs. A few days ago, the third brigade of the Criminal Investigation Detachment of Hongqiao Branch of the Public Security Bureau successfully destroyed this gang, arrested 7 suspects and collected more than 40 sets of equipment.
