The Burner Phone in The Boyfriend: A Symbol of Hidden Identity and Control

What Is the Burner Phone in The Boyfriend?

In Freida McFadden’s psychological thriller The Boyfriend, a burner phone is a cheap, prepaid mobile device used to conceal the user’s real identity and phone number. While the term “burner” appears only in Chapter 52 — when Sydney discovers the hidden device in Tom’s dresser — the concept of a secret communication channel recurs throughout the novel. Tom Brewer uses a burner phone exclusively to contact Sydney Shaw, and later we learn that Bonnie’s secret boyfriend (likely Tom) also used one. The phone becomes a concrete emblem of deception, compartmentalized lives, and the control one person exerts over another in a relationship.

Where the Burner Phone Appears

The motif emerges in several key scenes:

How the Meaning of the Burner Phone Changes

The burner phone starts as a generic criminal tool in Chapter 12 — a way for an unknown killer to evade detection. By Chapter 39, it becomes a relationship red flag for Sydney, who feels Tom is evasive. In Chapter 51, it transforms into a symbol of intimacy turned sinister: Tom uses the phone to create a one-way channel where he alone controls contact. In the Epilogue, the phone is absent but its purpose — to keep Sydney in a bubble of Tom’s design — is fulfilled when he eliminates Kevin without her knowledge. The phone evolves from evidence to personal threat to a instrument of twisted protection.

Character Connections

• Tom Brewer: The burner phone is an extension of Tom’s psychopathy. He compartmentalizes his relationships: a phone for work, a phone for his mother, a phone for Sydney, and likely a phone for Bonnie. It allows him to keep Sydney unaware of his violent past (the deaths of Brandi Healey, Alison, and possibly others). The phone also lets him “protect” her in his own way — as shown by the epilogue note — without ever exposing his true self.

• Sydney Shaw: For Sydney, the burner phone represents the gap between who Tom pretends to be and who he is. Finding it shatters her trust and forces her to accept that she has been dating a man capable of murder. Yet in the epilogue, she chooses not to turn Tom in, making the phone a symbol of her own complicity in the deception.

• Bonnie Driscoll: Although dead before the story begins, Bonnie’s relationship with a man who used a burner phone sets the pattern. She never knew his real identity, and that secrecy cost her life. The scrunchie Sydney finds in Tom’s bedroom (the same style Bonnie wore) connects Bonnie directly to the burner phone user.

• Gretchen Driscoll: Gretchen dismisses Sydney’s concern about the phone (“He could be telling you the truth”), representing the naiveté that allows deception to thrive. She herself is dating Randy, the actual killer, and misses all the signs.

• Randy Muncy: Though Randy does not use a burner phone, he is the building super who has keys to every apartment. The burner phone motif contrasts with his physical access: Tom uses technology to hide, Randy uses proximity. Both are examples of hidden predation.

Theme Connections

The burner phone ties directly to several central themes of the novel (see also the themes page):

• Deception and Identity: The burner phone is the physical manifestation of a false identity. Tom’s real phone is never used with Sydney; he maintains a digital mask. This theme echoes the online dating deception explored in chapters 1-2 (Kevin’s fake profile).

• Obsessive Love: Tom’s obsession with Daisy (and later Sydney) is enabled by the burner phone. He can contact Sydney whenever he wants, but she cannot reach him on his main number. This one-sided control is a hallmark of obsessive love, which you can read more about on the obsessive love theme page.

• Violence and Control: The burner phone is a tool of control. Tom decides when and how to communicate. In Chapter 51, Sydney realizes she has never called Tom on his regular phone — he has always initiated or responded on the burner. This control escalates to the violence he inflicts on Kevin and, earlier, on his father. For more, see the violence and control theme page.

• Trauma and Survival: Sydney’s discovery of the burner phone traumatizes her, but she survives by escaping Tom’s apartment. The phone represents the hidden danger that nearly destroys her. Her decision in the epilogue to discard the note shows her choosing survival over justice. This connects to the trauma and survival theme page.

• Justice vs. Complicity: The epilogue raises the question: should Sydney have given the note to Jake? The burner phone is gone, but the choice to destroy Tom’s message makes her complicit in his vigilante justice. Explore this further on the justice vs. complicity theme page.

Study Questions

Below are four questions designed to deepen your understanding of the burner phone symbol. Each includes a detailed answer based on the text.

1. Why does Tom use a burner phone instead of his regular phone to call Sydney?

Tom uses a burner phone to keep his relationship with Sydney completely separate from his other life. As revealed in Chapter 51, the burner contains only calls and texts from Sydney. This separation allows him to maintain a façade of normalcy with his mother and coworkers, while also concealing his violent past (the murders of Brandi and Alison, the killing of his father). The burner phone is a security measure: if Sydney ever got suspicious and checked his main phone records, she would find nothing. It also gives him total control — he can vanish at any time by discarding the phone, as he does with Gretchen (they disappear together at the end).

2. How does the burner phone connect Bonnie’s murder to Tom?

In Chapter 12, Detective Sousa tells Sydney that Bonnie’s secret boyfriend used a burner phone, making that man the prime suspect. Sydney later finds a black scrunchie in Tom’s bedroom — the same style Bonnie wore (Chapter 51). Combined with Tom’s strange reaction when Sydney mentions Bonnie’s building (Chapter 32) and his evasiveness about his phone (Chapter 39), the burner phone creates a direct link. The circumstantial evidence suggests Tom was Bonnie’s lover, and when Bonnie wanted to end things or expose him, he killed her. The burner phone thus becomes the thread that ties the two women’s stories together.

3. In what ways does Sydney’s reaction to the burner phone change over the course of the novel?

Sydney’s reaction evolves from skepticism to fear to moral compromise. In Chapter 43, she tells Gretchen the phone behavior is “super weird” but still excuses Tom as a workaholic. By Chapter 51, after finding the burner, she is terrified — she steals Tom’s water bottle for fingerprints and flees his apartment. After breaking up with Tom (Chapter 58), she blocks his number and believes him dangerous. Yet in the epilogue, when she receives his note about Kevin, she hesitates about turning him in and ultimately throws the evidence away. Her final act shows that the burner phone’s legacy is not just fear but also a choice to accept Tom’s “help” and move on, blurring the line between victim and accomplice.

4. What does the burner phone reveal about power dynamics in Tom and Sydney’s relationship?

The burner phone reveals a completely one-sided power dynamic. Tom controls all communications: he can call or text Sydney whenever he wants, but she can only reach him on the burner — and only when he chooses to answer. He never gives her his real number. This asymmetry mirrors the larger imbalance in their relationship: Tom knows Sydney’s fears, her apartment location, her history with Kevin, while Sydney knows almost nothing about Tom’s past (the girl Daisy, his father, his homicidal fantasies). The burner phone is the physical symbol of that knowledge gap. When Sydney finally discovers the phone, she briefly regains power by taking the water bottle, but Tom’s reaction (catching her) shows he is always one step ahead. In the epilogue, Tom reasserts control by eliminating Kevin without Sydney’s consent, leaving her to decide whether to expose him — a decision she makes based on gratitude rather than justice.
