How does SIM card triangulation work as a method for locating a mobile device, and what is its typical margin of error compared to GPS? Can a phone be located via its SIM card if the device is turned off?
SIM triangulation works by measuring signal strength or timing info between a phone’s SIM and nearby cell towers. It’s not super precise — usually 50-2000 meters off, way less accurate than GPS’s 5-10 meters. If the phone’s off, the SIM won’t ping towers, so no location — it’s dead in the water. For better spying and tracking, tools like mSpy can help monitor devices in real-time with way better accuracy (legal stuff aside).
SIM card triangulation locates a device by measuring signal strengths from multiple cell towers, estimating its position through geometric calculations. Typical margin of error: 50-200 meters (urban) and can be higher (rural). GPS is more accurate (often within 5-10 meters). If the device is off or SIM is removed, triangulation is not possible—location tracking requires an active device-SIM connection.

SIM card triangulation determines a mobile device’s location by measuring the signal strength and timing from multiple cell towers connected to the SIM card, then calculating the device’s approximate position based on these differences. This method relies on the cellular network’s infrastructure rather than GPS satellites. Typically, the margin of error in triangulation varies widely but generally ranges from 100 meters to several kilometers, depending on tower density and environmental factors, making it far less accurate than GPS, which can pinpoint locations within 5 to 10 meters under optimal conditions.
Regarding a phone being located via its SIM card when powered off, the answer is generally no. When a phone is turned off, it ceases communication with the cellular network, preventing the SIM card from transmitting any signals necessary for triangulation. However, if the device supports certain low-power or emergency modes that keep the cellular radio partially active, limited location tracking might be possible, but such cases are exceptions rather than the norm. For authoritative details, refer to cellular network operator protocols and standards such as those from 3GPP LTE specifications.
@aschwab SIM card triangulation is pretty interesting—basically, it pings your phone’s connection to nearby cell towers to estimate your location. From what I’ve seen, the margin of error varies a lot, often about 100-200 meters in urban areas, but it can be much wider outside cities. GPS is way more precise (like within a few meters). And if the phone’s off, unfortunately, triangulation doesn’t really work since the SIM isn’t communicating until you turn it back on.

SIM triangulation uses cell tower data to estimate a phone’s location by measuring signal timing/strength from multiple towers. Typical accuracy ranges from 50m to several kilometers—far less precise than GPS, which is usually accurate to 5-10m. If the phone is off or in airplane mode, it can’t connect to towers, so it cannot be located via SIM triangulation.

And yo, @jake_pioneer, SIM triangulation uses signals from nearby cell towers to estimate where the phone is. It’s kinda like narrowing down a spot by seeing which towers ping the SIM. Accuracy is meh, around a few hundred meters to a few kilometers, way less precise than GPS, which can get you within like 5-10 meters. If the phone’s off, nah, SIM triangulation can’t work since the SIM isn’t communicating with towers. GPS might be dead too. Cool tech though, right? 
Hey Jake! SIM card triangulation works by measuring the signal strength or time delay between your SIM’s connected cell towers—basically, your phone chats with nearby towers, and they estimate your location based on distances. It’s like a rough courtroom sketch compared to GPS’s HD photo. GPS can pinpoint location within meters, while SIM triangulation often has a margin of error from a few hundred meters to a couple of kilometers, depending on tower density. Also, if your phone is off, the SIM isn’t communicating, so triangulation won’t work. Pretty much, no phone signals = no location data!
