**1018 The defendant contends that by glancing at the ringing cell phone and observing a text message on its outer screen, the officer conducted a search. In a motion to suppress, the defendant bears the initial burden of establishing that a search occurred pursuant to the Fourth Amendment to the United States Constitution. See Commonwealth v. D'Onofrio , 396 Mass. 711 , 714-715, 488 N.E.2d 410 (1986). See also Commonwealth v. Boyarsky , 452 Mass. 700 , 708, 897 N.E.2d 574 (2008), quoting Commonwealth v. Netto , 438 Mass. 686 , 697, 783 N.E.2d 439 (2003) ("burden is initially on the defendant[ ] to demonstrate that [he] had a reasonable expectation of privacy .... Thus, if the record is unclear ... it is the defendant[ ] -- not the Commonwealth -- who [has] failed to meet [his] burden of proof ...").

The record before us presents a dearth of evidence concerning the cell phone. It is clear, however, that the defendant's cell phone was seized during a valid search incident to his lawful arrest. See Commonwealth v. Mauricio , 477 Mass. 588 , 592, 80 N.E.3d 318 (2017). At some point after the defendant's cell phone was lawfully seized and the officer returned to the police station, the cell phone rang. In response, the officer glanced at the outer screen of the ringing cell phone, where he observed the text message at issue. There was no evidence that the officer opened the cell phone, manipulated it to view the text message, or otherwise perused its contents. Because the record is devoid of evidence suggesting that the officer's observation of the outside of the defendant's cell phone constituted a search, the defendant did not establish that a search occurred. 1 Accordingly, within this factual vacuum, we cannot say that the judge erred in denying the motion to suppress.

Evidence at trial . The officer's testimony about the drug deal substantially conformed to the evidence presented at the hearing on the motion to suppress. The *240 officer observed the defendant meeting with another individual and conducting a hand-to-hand drug transaction in the parking lot behind a grocery store. Several "no trespassing" signs were prominently posted around that area of the parking lot. As the defendant was completing the drug deal, the officer approached the defendant. The defendant fled the scene but was arrested moments later. The officer recovered money and a cell phone from the defendant's pockets and observed a plastic bag containing cocaine fall from the defendant's pants.

The officer testified that the cell phone recovered from the defendant was a "flip phone." As the officer was writing his report at the police station, he heard the defendant's cell phone ring. In response, he glanced at its outer screen and saw a text message: "N word, I need some shit." 2 The officer testified that he had not opened the cell phone or otherwise manipulated it to view the message appearing on the outer screen. The cell phone was admitted in evidence.

Another officer testified that individuals looking to buy drugs will often contact a drug dealer through text message, and use coded words indicating that the person wants to meet to purchase drugs. That officer testified that a person found in possession of one small rock of cocaine, multiple twenty dollar bills, and a cell phone with a coded text message is more consistent with an individual dealing drugs than a personal user.

**1019 Testimony concerning the text message . The defendant principally claims that the officer's testimony about the content of the text message constituted impermissible hearsay and should not have been admitted. 3 However, "the words used to effectuate the commission of a crime, or to make a contractual promise or describe its terms, or to form a criminal conspiracy or set forth its aims" are legally operative words that do not constitute hearsay. Commonwealth v. Purdy , 459 Mass. 442 , 452-453, 945 N.E.2d 372 (2011). See Mass. G. Evid. § 801(c) (2018). In the same way that statements "compris[ing] a solicitation of a sexual act, including any negotiations regarding the price or services," are legally operative words, Purdy , supra at 452, 945 N.E.2d 372 , a statement in a text message asking to buy drugs is composed of the words of a crime and does not constitute hearsay. 4 Accordingly, there was no error in admitting the testimony.

Criminal trespass . The defendant contends that there was insufficient evidence to support his conviction of criminal trespass. General Laws c. 266, § 120, provides:

"Whoever, without right enters or remains in or upon the ... improved or *241 enclosed land ... of another ... after having been forbidden so to do by the person who has lawful control of said premises, whether directly or by notice posted thereon, ... shall be punished ...."

The phrase " 'without right' ... connote[s] the absence of any right, permission, or license recognized by law as permitting an entry into an area described by the statute." Commonwealth v. Wolf , 34 Mass. App. Ct. 949 , 951, 614 N.E.2d 679 (1993), citing Hurley v. Hinckley , 304 F.Supp. 704 , 710 (D. Mass. 1969), aff'd sub nom. Doyle v. O'Brien , 396 U.S. 277 , 90 S.Ct. 603 , 24 L.Ed.2d 469 (1970). In the circumstances of this case, there was insufficient evidence to establish that the defendant had entered onto the grocery store property "without right." Similarly, as it related to the facts before us, there is nothing suggesting that once the defendant entered onto the premises, he was provided adequate notice that he had been forbidden to remain thereon. Accordingly, we conclude that there was insufficient evidence in this case to support the defendant's conviction of criminal trespassing.

The defendant's conviction of possession of cocaine with intent to distribute is affirmed. The defendant's conviction of criminal trespass is reversed.

So ordered .
