Can I open the short message sent by Yijing College?

I often receive text messages from Yijing College because:

1. Mobile phone number registered the account of Yijing class and learned about the relevant course content. The system will judge that it is a potential customer, so it will send a sales message to this number.

2. fraudulent text messages. Fraud gangs will use the ip of Yijing class to post link messages. Please fill in your personal information after clicking the link. Never fill it in, in case the information is leaked. You can block short messages by adding blacklists.
