What is the situation of Hangzhou SF SMS?

As far as I know,10690333111is not the number of SF SMS platform. It should be a scam. Don't be fooled, dear.

As for how to know your number, they have many channels, usually mass messages. As long as you don't believe it, if you don't feel at ease, you can call SF National Unified Customer Service for enquiry.

SF's incoming SMS template seems to be like this:

You sent it to (a city) (freight order number) on (month). good name

I hope it is useful to you, please adopt O(∩_∩)O~
