Seek the method of opening short messages for roaming in Guangxi mobile area ~ I don't want to play artificial service ~

Hello, if you are a GSM customer, you can open a GSM roaming package in 5 yuan by sending a short message from 4073 to 10086. When roaming in 5 yuan/month, answer all calls in Guangxi free of charge.
