Mobile phone return problem
If you want to return your mobile phone in JD.COM, it depends on whether the goods you bought are self-operated in JD.COM, and there is no reason for JD.COM to support self-operated goods for 7 days. If it is a product of a third-party merchant, please check the product introduction. There is no reason whether it supports 7 days.
Advantages of self-operated stores
Self-operated stores should be the first choice for shopping in JD.COM, because the quality, distribution and after-sales of self-operated goods are better than those of third parties.
Physical store purchase suggestion
Personally, I think it is recommended to buy high-priced electronic products such as mobile phones in physical stores, which involves an after-sales service problem. It is still troublesome to buy online, and the after-sales service of specialty stores is still relatively good.
