There are a few options to text someone from a different phone number.
Spoof service: this type of service sends a text message to the number chosen by you and shows any number as the sender.
Third-party apps: these apps make it possible to send anonymous text messages and hide your phone number or show a random, fictional sender.
Anonymous text services: text services like us also make this possible, however, you being anonymous is 100% guaranteed, and the costs are only %price%.
