Why Do SMS Sender IDs Matter?
When you receive an SMS, the sender name (such as VK-ABCDEF or AD-XYZ123) provides clues about who sent the message and what type of message it is.
Recognizing these identifiers can help you distinguish between government notifications, promotional offers, service updates, and potentially suspicious messages.
Common SMS Categories
