Group 1: Changes in Operator Practices - Mobile operators have begun displaying advertisements in the signal bar, with different ads shown in various regions [4][5]. - This new feature allows operators to change the mobile operator identification displayed on devices through base station signals [5][23]. - The previous method of displaying operator names relied on the SIM card and base station signals, but this has been altered to prioritize base station messages [23][20]. Group 2: Technical Specifications - The change in display logic means that the base station's NITZ message now takes precedence over the SIM card's pre-set name [21][23]. - The new requirements from China Mobile and China Broadcasting specify that mobile manufacturers must support customized logo displays and prioritize NITZ messages [15][19]. - The NITZ message can be modified by operators, allowing them to display various advertisements without user consent [23][29]. Group 3: Regulatory and Compliance Issues - The actions of mobile operators may violate the 3GPP's established rules for operator name display and could potentially breach domestic advertising laws [24][29]. - There is a call for regulatory bodies to intervene and establish guidelines to govern the marketing practices of mobile operators [41][40]. Group 4: User Experience and Feedback - Users have expressed mixed feelings about the advertisements, with many finding them amusing rather than bothersome [36][40]. - There are suggestions for operators to use this space for important notifications, such as service interruptions or account issues, rather than advertisements [35][34].
