Online surveys also fall into the same category as the caveat for those is also the provision of your contact information. You can use this method to sign up for all these trials, giveaways, and surveys using the target phone number.

How to Spam Phone Numbers with Texts?
Spamming a phone number with texts can be achieved using auto-sender apps or websites that allow users to send mass messages. Another technique involves using email-to-text gateways provided by mobile carriers. For example, sending an email to a number formatted as an address (such as [email protected] for Verizon) can result in the message being delivered as a text. Subscribing a number to mailing lists or alert services via these gateways can flood the recipient with unwanted messages. It’s important to note that text bombing can be considered harassment and may have legal consequences.
