What does it mean to add numbers, letters and net to a short message?

International SMS, but it is likely to be fraudulent SMS.

Net is the abbreviation of network, which stands for the main network support center and provides network services.

Fraudulent SMS scams by adding links and contacts. The pages of fraudulent websites are highly induced, and once clicked, they are easily misled and deceived. After adding the contact information, I will also use various routines to lure you into the trap. So don't click on the link and don't add contact information.
