1. Since the mobile phone is a second-hand commodity after being connected to the Internet, the conditions for consumers to return goods should comply with the relevant laws and regulations, but the premise of returning goods for seven days without reason is that the goods have not been used, so the mobile phone no longer enjoys the right to return goods for seven days without reason after being connected to the Internet.

2. If the mobile phone has quality problems or is inconsistent with the real thing when it is sold, consumers can defend their rights through legal channels. The specific details of the mobile phone return policy need to be determined according to the regulations of different regions and brands, and consumers need to understand the relevant policies before choosing to buy. At the same time, good after-sales service is also one of the important factors in choosing mobile phone brands.
