A SIM card gives you the ability to have conversations and send text messages around the world. It’s also a gateway to your bank, social media, and other personal information. In case of phone theft, you can block your SIM card quickly by contacting your carrier. It’s crucial to act quickly before the thief uses your SIM card with ill intent and deals a heavy blow. We suggest enabling SIM card lock in the settings to add an extra layer of security to protect your SIM card on Android if your device has a SIM card slot.
