"SMS (Bangerz)" is a pop song, which incorporates elements of hip hop. Garrett stated that its concept was inspired by the female rap trio Salt-n-Pepa, and noted that the final track was "like five different things, it's hip-hop, it's the girls, it's a female anthem, Salt-n-Pepa, [and] Britney and Miley". He further opined that the women's collaboration made for a "historical moment [...] as big as when Britney kissed Madonna". Speculation of a collaboration between Cyrus and Britney Spears first arose after they shared a brief exchange over Twitter in July 2013. The following month, producer Sean Garrett confirmed that the pair had recorded a "nuts" collaboration for Bangerz. He later stated that Cyrus "[was] throwing around those ideas" of featuring Gwen Stefani and Nicki Minaj as the guest vocalist, but felt that the final cut with Spears was "absolutely the right one." Cyrus has told MTV News that she wants "SMS (Bangerz)" to be serviced as the third single from Bangerz.
Upon its release, "SMS (Bangerz)" received generally mixed reviews from music critics. Nick Catucci of Entertainment Weekly provided a favorable review, calling the track one of the best included on Bangerz and describing it as "a merry rap-off with Britney". Caroline Sullivan from The Guardian opined that Spears' inclusion was "a stroke of skewed inspiration", which contributed in making its parent album Cyrus' "game-changer". Writing for Slant Magazine, Kyle Fowle called the song an "Auto-TunedEuro-house jam" that helped make the album both "a message of empowerment" and "a straightforward party album".
In contrast, Mariah Eakin of The A.V. Club provided a more mixed review, saying that "Cyrus absolutely cannot rap, as horrifyingly evidenced by her Kreayshawn-like turns" highlighted in the track. Evan Sawdey from PopMatters cautioned that "braggadocio can only go so far (especially with a song that features such a formless sense of melody)", and felt that Mike Will Made It has a "horrid sense of how hooks work, leaving a slew of missed-attempts and mangled opportunities in his wake."
