What To Look Out For

Similar to identifying fake Facebook competitions, there are some simple things to be on the lookout for when it comes to spotting mobile phone scams.

The scam is really to trick you into calling back and when you do call back, you may be enticed into listening for longer and the longer you stay on, the more it’ll cost you

The main thing is to recognise the phone number that is ringing you. Restricted numbers may not be everyone’s cup of tea, but they’re generally safe enough to answer. Numbers in your contact list are a given. It’s when an unknown foreign number rings that you need to be wary.

Most smartphones nowadays are able to identify where a call is originating from, simply by tracking the number against international dialling codes. You can also tell a call from a foreign number, as it will start with a “+” symbol at the start.

Ultimately, it’s down to being careful about what calls you answer and call back. If you are unsure of why you’re receiving a random call from a Moscow number, it’s best to ignore it. You didn’t enter the Russian Lotto so how could you have won it?

Increase Security on your Mobile

While keeping an eye on who is ringing you will protect against mobile phone scams, we’re all human. Mistakes can be made. Your smartphone likely has some call blocking options on your smartphone to instantly reject calls from selected numbers or all calls from unknown numbers. If you do catch a rouge call from an odd number, just jot down that number for blocking later on.But there’s also a host of applications available for smartphones that allow you to call block automatically.

After some research, we came across Mr Number, an application available on both Google Play and iTunes. It allows you to block unwanted calls and SMS messages if you want to. However, you can also block individual numbers, if you want to avoid calls from the mother in law or block all calls from a particular country to make sure you’re fully covered against scams from a particular country.

The iOS version also has a slick feature, where you can automatically add a number to your block list as it is ringing you. Mr Number also has a database of previous mobile phone scam numbers, which will automatically be blocked upon installation of the app. You can also block any pesky spam messages that might be getting. And best of all, it’s free.
