Sim cards are small plastic cards that contain information about the user's phone and their connection to the mobile network operator. But did you know that the word "sim" refers to the number 7?
This comes from the abbreviation "Subscriber Identity Module," which is used to describe these cards. In many countries, including Ukraine, the sim card number consists of seven digits, hence the name "sim card."
