What does it mean to suddenly receive a text message and successfully recharge across New Focus?

I suddenly received a text message to recharge the new Focus. It should be that someone charged the wrong number when recharging, or maybe your number was originally used by someone else, and then he charged the original number by default when recharging.

Short message: ShortMessageService, short message service for short, refers to the text or digital information directly sent or received by users through mobile phones or other telecommunication terminals. The number of characters that users can receive and send short messages at a time is 160 English or numeric characters or 70 Chinese characters.
