Never used e-charge, but received a text message.

It may be a problem of personal information leakage.

Mobile phones will not receive a large number of short messages with verification codes for no reason. Generally, because your mobile phone number is leaked, some criminals will bombard your mobile phone number with spam messages such as verification code in a short time. You can download mobile phone security software to intercept. In the security interception settings, you can intercept short messages with strange numbers, and then open the notification icon on the mobile phone desktop. When there is a new message, it will not shake or ring, and it will not affect other operations. Add all used contacts to the card book or white list, intercept the information and receive it normally.
