The FCC this week voted to classify SMS and MMS as “information services,” denying requests from Twilio and others to regulate text messaging more strictly under the classification of “telecommunications services.”

Twilio, a company that sends texts for other companies, had petitioned the FCC in 2015 requesting the classification under Title II.

The 3-1 vote removes regulatory uncertainty and gives wireless providers the greenlight to continue efforts to prevent unwanted spam text messages from inundating consumers, according to proponents of the decision. Opponents, including dissenting Commissioner Jessica Rosenworcel, contend that the classification does not provide new abilities to stop robotexts, but rather gives carriers the right to block text messages and censor content.

“The FCC shouldn’t make it easier for spammers and scammers to bombard consumers with unwanted texts. And we shouldn’t allow unwanted messages to plague wireless messaging services in the same way that unwanted robocalls flood voice services,” FCC Chairman Ajit Pai said in a statement. “But that’s precisely what would happen if we were to classify text messaging services as telecommunications services and subject them to common-carrier regulation under Title II, as mass-texting companies and others have asked us to do.”
