How to send a message to the Big Dipper by mobile phone?

It's more troublesome to get to the ship by mobile phone: need to edit the SMS prefix? Just add content after the big dipper # terminal number.

Mobile users send it to: 106575008230 Unicom sends it to: 10669 1600.

Getting to the mobile phone by boat is very simple: just fill in the phone number of the contact person and press send.

When you say you can't get it, do you mean you can't get it on your mobile phone? Does that mean you can just send your mobile phone to the boat? As long as the unilateral transmission is successful, it means that there is no problem with the equipment.
