Can police wiretap my phone?
In the United States, police cannot simply monitor or wiretap your new phone without first obtaining legal authorization, such as a search warrant or wiretap order issued by a judge. The Fourth Amendment protects individuals against unreasonable searches and seizures, meaning law enforcement must show probable cause to a court before they can intercept communications, install monitoring software, or otherwise access the private content of your device. The fact that your old phone was seized as part of an investigation does not automatically give them ongoing access to any new device you purchase; each search must be separately justified and approved. However, if you use the same accounts (email, social media, cloud storage, etc.), investigators could seek warrants directed at those service providers to obtain records, so the risk comes less from the new hardware itself and more from the continuity of your digital accounts.
Practically, this means that while police cannot secretly “turn on” your new phone to monitor you without a court order, any accounts linked to the investigation could still be lawfully accessed through proper legal channels. If you are under investigation for serious charges such as CSAM possession, law enforcement is likely to pursue those avenues, but they remain bound by constitutional and statutory limits (18 U.S.C. § 2252A(a)(5)(B)). Because of the potential severity of such allegations, you should avoid transferring or creating any potentially compromising data, and you should strongly consider speaking with a defense attorney about how to protect your rights. A lawyer can review whether the initial seizure was lawful, explain what surveillance tools police may have sought, and advise on how to avoid unintentionally exposing yourself to additional risk while the investigation is pending.
Does that make sense?

If I am being investigated and I got a new phone because my old one was seized, can police be monitoring my new one?

I’m sorry to hear about your situation. Have you been formally charged with any crime related to the investigation?

No, not yet.

Did you transfer any data or accounts from your old phone to the new one?

I don’t know.

Is there anything else the lawyer should know before I connect you? Rest assured they’ll be able to help with police monitoring your new phone.

No.

Good afternoon and welcome. Please give me a moment to review your question. Note that I am a hearing-impaired expert and phone calls are difficult for me—thank you for understanding.

No problem.
