What's in the micro-express?

Micro Express is not a courier company, but many couriers use his short message channel to send short messages to recipients, which can be much cheaper. Micro-express is for express mail inquiry, and all recipients are their target groups, so couriers use their short message channels to send short messages. By default, they will add the prefix of micro-express to help them advertise, which is nothing. Micro-express is mainly used to check express delivery, and you can also use it. Personally, it's not bad, especially for people who often shop online.
