Is it true that SMS received the internal number of the game?

It's true. In the game circle, some players will receive text messages or phone calls about the internal numbers of mobile games. The full name of the internal number is the internal test account. These accounts were originally tools to help game testers quickly experience gameplay and eliminate bugs. They are strictly controlled by the game company. The main purpose is to stimulate players to enter the game consumption and drive more players to recharge, so it is true.
