I'm trying to factory reset a phone. How do I erase "downloaded SIMs"? I have Google Pixel. When trying to factory reset it, it says &quot;downloaded SIMs may remain on the device&quot;.
What does that mean? How do I erase these data?
The &quot;downloaded SIMs&quot; here refers to embedded-SIMs (eSIMs).
According to the AOSP source code, looks like the error message happens when the Factory Data Reset fails to erase eSIM data.

&lt;!-- Factory data reset erase eSIM failure text [CHAR LIMIT=none] --&gt;
&lt;string name=&quot;fdr_esim_failure_text&quot;&gt;Please reboot the device and try again. If you continue factory reset, the downloaded SIMs may remain on the device.&lt;/string&gt;


To erase eSIM data, try resetting the network settings first. For Google Pixel series,

Tip: To reset all your network settings, in your phone’s Settings app, tap System  Advanced  Reset options  Reset Wi-Fi, mobile &amp; Bluetooth.

Otherwise, to retain eSIM data through the Factory Data Reset, it should be possible to just continue the process when prompted.
