I bought a red rice 2 mobile phone online, is it limited to SF Express, but is mine booked by YTO Express?

I haven't heard that the mailing service of Xiaomi's mobile phone is contracted by SF.

Only SF is relatively the fastest.

Therefore, don't worry about which courier, as long as it is a mobile phone purchased through a regular channel, it will generally not be a fake.

As for after-sales service, Xiaomi has a designated maintenance point. You can check whether there is a maintenance point there.

Selling millet is not necessarily the after-sales point.
