Secrets Hidden in Your SIM Card

1: Stores Contact Information

• How It Works: The SIM card uses non-volatile memory to store phone numbers and names. This data remains intact even when the SIM is removed from the device.
• Importance: In case of phone damage or a reset, contacts stored on the SIM are retrievable without cloud backups.
• Hidden Potential: The stored contacts can be transferred across phones instantly, making it useful in areas with limited internet access.

• Hidden Potential: Stored SMS can be accessed on non-smart devices, a lifesaver during emergencies or battery-saving situations.
• Pro Tip: Regularly delete old messages to make space for critical ones.

3. Enables International Roaming

• How It Works: The SIM contains a unique IMSI (International Mobile Subscriber Identity) number that networks use to grant access when abroad.
• Importance: This allows seamless connection to foreign networks without needing a new SIM.

• Pro Tip: Use priority settings to ensure calls or texts are directed to the desired SIM.

10. Stores Personal Identification Numbers (PINs)

• How It Works: The SIM has space to store a unique PIN and PUK (Personal Unblocking Key) for added security.
