For businesses, sending text messages to hundreds, thousands, or perhaps millions of customers can be a laborious task.

A wide ecosystem of these companies exist, each advertising their own ability to run text messaging for other businesses.

Some firms say they only allow customers to reroute messages for business landlines or VoIP phones, while others allow mobile numbers too.

The cheapest plan, which allows customers to add a phone number they want to send and receive texts as, is where the $16 goes.

Sakari's LOA says that the user should not conduct any unlawful, harassing, or inappropriate behaviour with the text messaging service and phone number.

Once the hacker is able to reroute a target's text messages, it can then be trivial to hack into other accounts associated with that phone number.
