Taobao number protection is turned on. Why can a courier send a text message?

Hello, Taobao protection is a guarantee for buyers. If you turn on this function, the courier won't send you a text message because there is no way to contact you. However, if the service is closed, the courier can normally contact you by phone or SMS to confirm the delivery address and other related information. I have encountered a similar situation before! I set it up at that time, and both my mobile phone and email accepted the verification code! So you need to fill in the mailbox when shopping! Later, the seller blacked me out and asked for a refund! I hope I can help you! 1. If your account is frozen, please press 2. If your bound mobile phone number has changed, 3. Mobile phone number has been disabled, 4. Network problems, 5.
