Sending text messages to phone numbers of owners who have not opted-in to your SMS campaign is an illegal practice. It is a violation of federal law under the TCPA, and it can result in costly lawsuits. Consumers can sue you for sending them unsolicited messages, and they can claim between $500 and $1,500 for every unwanted text message that you have send to them.
A single SMS message has a maximum size of 1120 bits. This is important because there are two types of character encodings, GSM and Unicode. Latin-based languages like English are GSM based encoding, which are 7 bits per character. This is where text messages typically get their 160 character per SMS limit.[13] Long messages that exceed this limit are concatenated. They are split into smaller messages, which are recombined by the receiving phone.

Mobile marketing differs from most other forms of marketing communication in that it is often user (consumer) initiated (mobile originated, or MO) message, and requires the express consent of the consumer to receive future communications. A call delivered from a server (business) to a user (consumer) is called a mobile terminated (MT) message.

In the article cited at the beginning of this post, the author boldly claims that “a major chunk of the population is already registered with the DND.” First, there is no clear statistical research backing up this assumption. Second, in the U.S., the Do Not Call registry protects consumers from just that — unwanted calls. It’s designed to prevent telemarketers from harassing consumers. This has absolutely nothing to do with text messaging. Now, if for some reason you do find yourself receiving unwanted text messages, you can file a complaint. But, knowing the permission-based nature of this marketing method, you may never confront this issue.
The new Telephone Consumer Protection Act guidelines going into effect on October 16th 2013 require written, auditable consent for every consumer in a mobile database whereas previously consent could be express, meaning a company had previously done business with an individual.
