Why Should TM Users Enable a SIM Card Lock?

This ensures TM users can maintain control over their SIM cards and avoid any potential misuse.

• Protects your SIM from unauthorized access.

Extra Tips for TM SIM Card Lock

• Pick a PIN You Remember: Choose a PIN that’s easy for you to remember but hard for others to guess. Don’t use simple numbers like “1234” or your birth date.
• Save Your PUK Code: Write down your PUK code and keep it in a safe place, away from your phone. This code is needed if you forget your PIN.
• Don’t Guess the PIN: If you’re not sure about your PIN, check your records. Entering the wrong PIN three times will lock your SIM.
• Change Your PIN Often: Update your PIN every few months to keep it safe. Use a new PIN that’s not easy to guess.
