If you have an Android device, there are a few ways to erase your SIM card memory. This is especially useful if you don’t want to keep your phone with the old SIM card in it.

  1. Open the Settings app and scroll down to the bottom of the screen. There you’ll find a list of options called “Storage.” Toggle on “Erase All Data” and press OK.
  2. Type in your phone’s address into the Erase All Data field and press OK.
  3. Tap on “Done” and your phone will erase all SIM card memory from its storage!
