A First-Time Smartphone User's Guide to Scams
New to smartphones, mobile money or banking apps? Five simple habits prevent most scam losses. A plain guide for first-time users and the family members helping them.

A smartphone opens up a lot: video calls with family, mobile money, banking, news, shopping. It also brings scam messages and calls that can be confusing if you are new to it all. You do not need to be an expert. These five habits prevent most scam losses, and they are easy to remember.
The five habits
1. Your PIN and codes are yours alone
Never tell anyone your PIN, password, or the codes sent to your phone by text. Not the bank, not the network, not a relative on a new number. Real staff never ask for them.
2. If it is unexpected, check it yourself
If a message or call says there is a problem, a prize or an emergency, do not use the number or link it gives. Call the organization using the number on your card or bill, or call your relative on the number you already have saved.
3. Do not rush
Scammers push you to act quickly: "today", "now", "or your account will be closed". When you feel rushed, stop. A real problem will still be there tomorrow.
4. Only install apps from the official store
Use the app store that came with your phone. Do not install apps from links in messages, and never install an app because a caller asked you to.
5. Ask someone you trust
If anything feels strange, show it to a family member or friend before you do anything. Asking is always the right choice.
Write the five habits on a card and keep it with your phone until they feel natural.
