How to change the short message of Guangdong Unicom for 3 yuan a month?

Customization: edit the short message UPRXDZ+ the number of the other party is 8 1 18.

Change: edit the short message UPRXGG+ the number of the other party is 8 1 18.

Cancel: edit the short message UPRXQX+ the caller number is 8 1 18.

Don't use the word "in the right place" when sending it! But you need to bind each other's real mobile phone number!

There is no charge for initial customization, and it will be charged for every change in the future, 3 yuan! !

It takes two people to bind each other's mobile phone numbers together! ! !
