How to stop nuisance calls to your mobile phone

With landlines becoming a relic of the past, the telemarketers have wheedled their way into our personal devices – and then some. These days, about 54% of mobile users find themselves of the receiving end of marketing calls at some point.

So how can we stop unwanted calls? And how do telemarketers and charities get hold of our mobile numbers in the first place? These are especially urgent questions in the era of COVID-19, as  research suggests that nuisance calls and texts

have risen during pandemic-related lockdowns.

How to stop telemarketing calls

1. Join the Do Not Call Register.

Registering your mobile number on the Do Not Call Register will stop most of the calls. Sign up at or phone 1300 792 958.

2. Mind your Ts & Cs

Nothing is for free! Check the fine print on online forms, competitions & contracts so you know what you are giving permission for.

3. Use a blocking App

Use a number blocking app or your smartphone’s number blocking feature to stop telemarketers’ calls getting through.

4. Learn to say no

Politely and firmly ask for your name to be removed from the call list. You can also ask to end the call whenever you want.

Telemarketers have to comply. 

5. Make a complaint

If the calls continue, complain directly to the company or charity. If you think a telemarketer has broken the rules, report it to the ACMA at donotcall.gov.au or 1300 792 958.

How do businesses get my mobile number?

Businesses can buy your number from companies that specialise in selling data. How did those companies get your data? You likely gave them access to it when you ticked ‘yes’ and agreed to the terms and conditions on a website or online competition.

Or sometimes marketers use random number generators and automatic dialing systems to track you down.

(In both these cases companies must first “wash” the data to remove any numbers on the Do Not Call Register, so if you’re registered you shouldn’t receive cold calls from companies you’ve never heard of.) And then other times you might hear from a company you have an existing relationship with.

How you give telemarketers permission to call – without even realising it

Businesses are allowed to contact you if you’ve given them permission either explicitly or implicitly – what’s known in the

business as ‘express’ and ‘inferred’ consent. It’s a bit like the difference between making a friend on Facebook

and in real life. On Facebook, you send a friend request and the person accepts. This is express consent – you’ve clearly asked and they’ve clearly answered yes.

In real life, you might meet someone at a party, have coffee a few times and then invite them to your birthday BBQ – you haven’t ever explicitly asked them to be your friend, but your interactions indicate that you might want them to be. This is inferred consent:

you have an existing relationship with them, so it’s reasonable to assume that they want to hear from you.

In the telemarketing world, inferred consent happens when you have an existing business relationship with a company: they can contact you to let you know about deals and products you might be interested in.

“But the entity still has to be contacting you in relation to that relationship,” says Jeremy Fenton, executive manager of unsolicited communications and cyber security at the Australian Communications and Media Authority (ACMA).


“So, if you have an account with a bank, it’s not necessarily okay for them to be contacting you selling, for example, insurance services. There is a direct consideration of the existing relationship and how the marketing contact relates to that existing relationship.” The problem is that you can give ‘express’ consent without knowing it. You might’ve filled out a form or entered a competition and ticked ‘yes’ to accept the terms and conditions, thereby giving permission for your number to be used for telemarketing – and perhaps even to be shared with or sold to other companies.  Calls from businesses are the most common type of telemarketing calls or texts received on mobile phones, so you should be aware when you’re agreeing to let them do it.

Unless otherwise specified, express consent lasts for three months from the date you consented, though in some cases it could last indefinitely.

The Do not call register

With around 11 million numbers on the Do Not Call Register – over four million of which are mobiles – it’s clear that Australians don’t like being pestered by businesses. Nevertheless, only 14% of mobile numbers were listed on the

register as of 2016, although the take-up for mobile numbers is significantly outpacing the take-up for landlines.

If you’re being swamped by calls, the Do Not Call Register is your first step. “It’s fast, free and confidential, dential,” says Fenton. “This will stop a majority of commercial calls.” Either visit or call 1300 792 958 to add your number

to the register. It’ll take up to 30 days for your registration to take effect. You’ll only need to register once – the registration is

indefinite. There’s no guarantee that this will stop every unwanted call, but it should significantly reduce them.

When does ‘Do Not Call’ mean ‘Do Not Call’?

Getting called after you’re joined the Do Not Call Register can make you wonder if it was worth the effort. Just when you thought you were in the clear, along comes another ‘chugger’ (charity mugger) from a marketing agency asking you to donate – calling, no doubt, just as you’ve sat down to dinner.

While the Do Not Call Register is a useful tool, it’s not a cure-all. “Some people … don’t necessarily understand that if they give

permission, telemarketers can actually call their number, even though it’s on the Do Not Call Register,” Fenton says. “And

sometimes people don’t really understand that they have given permission.”

Exemptions to the Do Not Call Register

Even if you’re on the Do Not Call Register, you can still be contacted by:

* registered charities

* opinion pollsters

* government bodies

* social researchers

* educational organisations.

These types of callers are allowed to bypass the Register, but they

do need to comply with the , which stipulates: Telecommunications (Telemarketing and Research Calls) Industry Standard 2017, when a telemarketer or researcher can call you what information they have to give you at the start of the call

the information they have to give you if you request it that they must terminate the call if you ask.

Nearly half of all major charities are members of the Fundraising Institute of Australia (FIA), which has its own code of conduct that purports to protect vulnerable consumers and claims to set a higher bar than the industry standard.

The self-regulatory code only came into effect on 1 January 2018, so at the time of publishing it’s difficult to say whether it will be effective, especially since it was drafted with very little consumer consultation. If you think an FIA member is breaching the code, you can complain directly to the charity, or to the FIA at: members@fia.org.au or 1300 889 670.

What to say to telemarketers

If you simply hang up on a telemarketer, your number could stay on their call list, so you may be hassled again. Some charities also obtain lists of current donors from other charities or professional fundraising companies, so if you donate to one you may start receiving calls from others. The best way to ensure they don’t keep calling is to ask them to remove your number from their list. ‘Polite but firm” should be your mantra when talking to telemarketers. The magic words are: “I want to be removed from your calling list” . They’re obliged to do so, and to terminate the call if you request it.

“I get lots of free ‘gifts’ in the mail from charities I’ve never even heard of, but I get no calls whatsoever, even from the ones I donate to regularly. Want to know the secret? When they call, ask them not to – that’s all I did,” says CHOICE.Community member Jessica.

“For charities that I donate to regularly, I specifically ask to be taken off their call list and warn them that if they phone me again I will cancel my donation. I never hear from them again. If other charities call, I ask not to be called and tell them I will not donate to charities hat call me. I can’t remember the last time a charity called me.”

Some professional fundraising companies represent multiple charities. If the fundraising company is an FIA member, you can ask them to remove your number from all their campaigns – they’re obliged to honour that request.

How to complain about unsolicited calls

Our research has found that 88% of people wish there was more they could do to stop unsolicited calls. There is – but you  have to take action. “Consumers have the power. They can give permission, and they can take it away,” says Fenton. “It doesn’t matter if the permission is direct or indirect – consumers have the power to take their permission away.”

If you tell a business you don’t want to receive telemarketing calls from them, they’re required to stop calling you – the consent ends then and there. (See ‘What to say to telemarketers’ for tips.)

If they do keep calling, contact the company or charity directly to complain. If that doesn’t work, bring out the big guns: complain to the ACMA.

Hiya- Caller ID & Block

In addition to blocking calls or messages and blacklisting numbers, it includes features like calls or messages and blacklisting numbers, it includes features like reverse phone number lookup and caller ID security protection.

Robo Shield

Although a new entry in the market among spam blocking apps for iPhone, Robo Shield has quickly distinguished itself as a highly effective tool for blocking unwanted calls. This app uniquely comes as part of a larger package of desirable privacy and security tools you may already be considering or may already be paying for individually. Here’s how Robo Shield fares in our review: App Store ratings/reviews: 5 points Customer service: 5 points Quality of features: 5 points Price: 4 points SPAM KILLING SCORE: 19/20 (95%)

You can send those calls directly to voicemail and not have to worry about picking up the phone.

True Caller

Truecaller commands a lot of respect in the phone spam blocking industry, and with good reason. It’s one of the largest and most used pam blocking apps in the world. It’s also one of the few options on our list with a 100 percent free subscription tier that is also effective at blocking spam calls on iPhones. Here’s how Truecaller fares in our review: App Store ratings/reviews: 5 points Customer service: 5 points Quality of features: 4 points Price: 5 points SPAM KILLING SCORE: 19/20 (95%)

Truecaller ratings and customer service This service has more than 200,000 user ratings on the App Store. Even with that many, it’s managed to retain a very respectable 4.5-star rating. Its ability to sustain such a high score speaks to the immense effectiveness of its tool and to its solid customer service. Truecaller is promising because: It is one of the only apps that we see responding not just to critical star reviews, but positive ones as well The company is constantly delivering helpful tips and responses in its App Store review section, even for those who have had a positive experience with the app Truecaller features On Truecaller’s features list, you’ll find: Caller ID (free) Spam call blocking (free) Profile creation (free) Extensive and detailed call history (free) Who Viewed My Profile (premium) Contact requests Incognito mode (premium) Call recording (premium) You’ll {nd that this app is absolutely over|owing with features. In some ways, that’s to its own detriment.

In fact, we gave Truecaller a slightly lower rating because most of the premium features feel somewhat gimmicky and unnecessary.

For example, the premium service comes with social-media-like features that let you see who viewed your Truecaller pro{le or allow you to get a gold-colored caller ID symbol that only appears for other Truecaller users. Thankfully, the core features (call blocking, caller ID) are all free and work extremely well. If the ad-supported model is not to your liking, the premium options do remove ads. Premium also adds a call recording feature, although that’s a feature you could get free with other apps.

 

Android devices and iPhones come with built-in features for blocking specific phone numbers, while mobile carriers offer their own blocking tools.
