Core Viewpoint - The three major telecommunications companies in China have collectively announced standardized measures for telephone marketing to address consumer complaints regarding false advertising and inducement to consume [1][2]. Group 1: Standardized Marketing Measures - The official outbound marketing numbers for the three telecommunications companies are: China Telecom 10001, China Mobile 10085, and China Unicom 10016. Any calls from other numbers should be considered unofficial [1]. - If a user explicitly refuses a marketing offer, the companies are prohibited from making further calls to that user [1]. - Marketing calls must provide comprehensive and accurate information, avoiding false advertising and ensuring transparency regarding pricing, applicable scenarios, validity periods, and restrictive conditions [1]. Group 2: Compliance and User Consent - All outbound marketing calls must be recorded and undergo full review to ensure compliance with strict quality standards [1]. - After obtaining user consent, staff must send a confirmation SMS detailing necessary information about the service being offered. The service will only be processed after the user replies to confirm via SMS [1]. - Upon successful processing of the service, a notification SMS will be sent to the user promptly [1].
