IF YOU DO MOBILE BANKING from your phone, there is a need to put a PIN on your SIM, otherwise, your account could be wiped clean anytime you lose your phone or your phone is stolen. The process to do is very simple but if ignored can cost you all Your life savings.
For those who don't know about it yet, just follow these simple steps to protect against the hacking of Your bank account through SIM THEFT.
1. Go to SETTINGS on Your phone.
2. Go to SECURITY & LOCATION under SETTINGS
3. Go to SIM CARD LOCK.
4. Click on LOCK SIM CARD.
5. Enter Your mobile network's default SIM CARD PIN.
For MTN users it is "00000"
(try this once or call your network provider so that can assist you with their default sim card pin or keep your PUK closed to)
6. After entering the MOBILE NETWORK DEFAULT PIN, under it You will see " CHANGE SIM PIN", click on it to change to Your unique 4-digit pin,
7. Confirm Your unique 4-digit pin by entering it again & YOU ARE DONE.
So anytime You switch your phone on, your phone will be prompted to enter Your SIM CARD PIN just as You will be prompted to enter Your phone lock PIN or Draw Your PATTERN each time You "START" (ON) Your phone.
With the ACTIVATION OF SIM LOCK on Your phone, Your money can never be withdrawn from Your bank account through your SIM because Your SIM will be useless in their hands since it is blocked and You will not be under tension to go and block or retrieve Your stolen SIM.
