Tracking a phone and blocking it are different remedies

"Find my phone" and "block my phone" get treated as two buttons doing roughly the same job. They are not comparable measures at all: they live in different places, fail for different reasons, and answer different questions.

Where each one runs

Tracking is software on the handset. It reports a position to a service, and for that to work the device has to be powered, connected, and still signed in to the account that owns it.

Blocking is a record held by networks, keyed on the IMEI. Nothing about it runs on the device. The handset is not consulted and cannot decline.

That difference is the whole of it, and everything else follows.

What a factory reset does to each

A reset removes the account, and with it the tracking, the remote lock and the remote wipe. Every protection that lived on the device goes at once, and it goes early — resetting is among the first things done to a stolen handset, not something that happens weeks later.

The block is untouched, because it was never on the device to erase. This asymmetry is why the two measures have to be used in a particular order rather than treated as interchangeable options.

Which to reach for, and when

Tracking is worth trying immediately and is worth very little later. Its window is measured in minutes, and it closes the moment the device is powered off or wiped.

Blocking is worth doing regardless of whether tracking worked, and it stays worth doing afterwards. It does not recover the phone; what it does is remove the reason to have taken it, by making the handset unusable on networks that honour the block.

What blocking does not do

It does not stop the device being used offline. A blocked handset still works as a camera, a music player and a games machine on wi-fi, which is why blocked stock still has a resale market among buyers who do not know or do not care.

It does not reach across borders on its own. Blocking registries are national, and a device refused in one country can register normally in another — which is precisely why stolen handsets travel.

And it does not protect the data. Everything on the phone is a separate problem with a separate remedy, and the account credentials matter more than the block does for anyone who kept anything important on the device.

Understanding the split matters most for the people selling these measures as reassurance. Tracking is not a security control; it is a lucky-recovery mechanism with a short shelf life. Blocking is not a recovery mechanism at all. Presenting either as the other sets an expectation that the technology cannot meet.
