Why can't I get the message when someone leaves the mobile phone number of something I ordered in Tik Tok?

It's normal that Tik Tok didn't receive text messages when shopping. It should be set by the seller to receive short messages. You can receive the goods without receiving the text message. If you want to see your order, you can enter Tik Tok and click I to view the order, or you can enter the title to view the order. It doesn't matter if you don't receive the text message, the seller will also deliver the goods.
