While it's unclear if you're looking for a way to send messages without a credit card or a tool to generate "fake" text image, there are several ways to do both.
Many services allow you to send real SMS or make calls over Wi-Fi without ever asking for payment information.
If you need texting for a business, several platforms offer free trials with no credit card commitment:
A popular choice that provides a free U.S. or Canadian phone number for unlimited texting and calling over Wi-Fi.
Offers a free start with fast registration and no card required for their SMS marketing software.
Offers a real phone number for free texting and calling from mobile apps or a web browser.
Provides a 14-day free trial to test their platform and send messages.
