Can the mobile phone online business hall delete the previous call records and SMS records?

Hello, you can't clear it yourself. If it is a Beijing mobile number, you can handle the "detailed list crushing" business. This business is divided into "monthly detailed list crushing" and "on-demand detailed list crushing". Monthly detailed list rolling: 10 yuan/month; On-demand detailed list rolling: monthly fee for on-demand 10 yuan. After applying for "monthly detailed list rolling", the system will immediately block your monthly detailed list. After blocking the detailed list, you cannot query the blocked detailed list through any channel. After you apply for "On-demand Detailed List Crushing", you can choose to clear the detailed list of any month in the past six months (excluding the current month). After applying for the detailed list crushing function, you will never be able to query the detailed list through websites, self-service terminals and other channels. If necessary, you can bring your valid ID card to the mobile business hall. Apply in the same month and take effect in the same month. Please refer to.
