I was having double thoughts revealing this, because the fraudulent ones amongst us will want to use it on innocent people. If you are in this category one day you will be caught and punished.

For the innocent ones.
Be mindful of who you give your phone because fraudsters are everywhere, they can be your close friends and family too.

They will borrow your phone either to quickly make a call, send a text or even take a pic....

When they get hold of your phone they start checking for your credit limit on your sim and use it to request for a loan (which comes with an interest) which would be paid into your acct. and tell you someone is sending them some amount of money to your account and beg you to use your ATM card to withdraw the money for them. Be wise.

Dia fada, I Dr wait for them

Why would u give out ur fone for any reason at all, it's a private property that contains informations about your whole world. Aside my wife no one dare ask me for my phone.
