Federal agents cannot legally tap your phone whenever they want to. They have to follow strict guidelines and go through a specific process to obtain approval.
The judge's order authorizing a wiretap can be no longer than 30 days. After 30 days have passed, the prosecutor has to go back to the judge and ask again. When the prosecutor asks again, he or she has to explain what the wiretap found in the first place.
Federal agents cannot simply start tapping your phone without first obtaining court approval. In its request, the Department of Justice must include a description of who will be subject to the wiretap and its details under 18 U.S.C. § 2518.
Are FBI special agents permitted to install wiretaps at their own discretion? No. Wiretapping is one of the FBI's most sensitive techniques and is strictly controlled by federal statutes. It is used infrequently and only to combat terrorism and the most serious crimes.
Police Must Obtain an Order to Tap Your Phone

Can you tell if your phone is being monitored? Yes, there are signs that will tell you when your phone is being monitored. These signs include overheating of your device, the battery draining fast, receiving odd text messages, hearing weird sounds during calls, and random reboots of your phone.
You can immediately check if your phone has been compromised, or if your calls, messages etc have been forwarded without your knowledge. All you need to do is dial a few USSD codes - ##002#, *#21#, and *#62# from your phone's dialer.
When you dial *#21#, it will display the various sorts of diversion status which is happening with the number. This will display the information and you will come to know if your calls or messages are tapped.
If a mobile phone is tapped, it is recording your activities and transmitting them to a third party. This leaves a footprint in the form of increased battery usage and as a result the battery loses life faster.
If your phone doesn't have a password or law enforcement is able to access it using specialized passcode cracking tools like Cellebrite or GrayKey — and they have the necessary search warrant to do so — then it's all theirs.
Under the Patriot Act, the FBI can secretly conduct a physical search or wiretap on American citizens to obtain evidence of crime without proving probable cause, as the Fourth Amendment explicitly requires.
Carriers cannot intercept iMessages because they're encrypted and routed over Apple servers—and the same thing applies to Facetime.
The police may obtain your opened and unopened messages that are 180 days old or older with a subpoena. But they have to let you know once they've requested this access from the provider. Law enforcement are allowed to access older, unread emails without telling you if they obtain a court order.

Lastly, with the *#002# settings interrogation short code, you can see all forms of call forwarding on your line. If everything says "Disabled," you have nothing to worry about. If there are numbers listed, they could be put there by someone else, or they could be the number for your voicemail box.
