How to send a text message without a mobile phone number?

SMS service providers can only provide services according to your account number, that is, your mobile phone number. Without your mobile phone number, you can't provide services, and of course you can't send text messages. However, you can use a mobile phone without a number to log in to a registered WeChat account or QQ to send information. In this case, to send information, the mobile phone must have a WIFI signal and be able to connect this signal.
