DMA launches TPS Protect to put an end to nuisance calls

The DMA has launched a new mobile app to help consumers avoid nuisance and scam calls, called TPS Protect. Developed in partnership with First Orion, the app offers an easier way for consumers to avoid unwanted calls, register their mobile number with the Telephone Preference Service (TPS) and quickly register complaints about nuisance or scam calls. Available on Android [link TBC] and Apple [link TBC] handsets, users can benefit from the app as soon as it's downloaded, completely free. New users will also receive a free 60 day trial of the additional paid-for features available.

How does it work?

TPS Protect is an app that rates incoming calls with a trust score from 1 to 5, indicating whether the caller is a scammer with criminal intentions or someone you can trust. This is called the Trust Score and it will be displayed for incoming calls, so that if the user receives a call with a low Trust Score they can simply reject the call.

TPS Protect also provides a category for the call too, so even if it's a mid-level Trust Score, users can decide whether they want to pick up the call from a Charity or Financial Services company. The aim is to provide as much information to the user as simply as we can, so they can make an informed choice. The data is always updating too, every 6 minutes in fact, so we can provide up to the minute protection and start to protect consumers quickly if a new scam appears (for example).

What's a Trust Score?

The TPS Protect app's Trust Score is an indicator created to help users work out who is calling and whether they should pick up or not. The information provided by users helps TPS Protect to better understand whether callers are legitimate businesses, nuisance callers or scammers, allocating an appropriate score according to all the information available. Once enabled on their phone, users can immediately start to see the Trust Score for any incoming call, enabling them to decide whether they want to pick up or not.

Users are able to set their Trust Score from 1 to 5, enabling them to control the overall level of protection they receive. A score of 5 is the highest level of protection, sending all telemarketing and scam calls to voicemail that have a trust score lower than 5, only allowing telemarketers that have received very few complaints and your approved list to ring your phone. A score of 3 will allow calls from most call centres, sending to voicemail those with a score of 1 and 2 which indicates many customer complaints. A score of 1 will allow all calls, including those from suspected scammers.

How much does it cost?

It's free to download for Android and Apple devices and users will always be able to see 'Trust Scores' for incoming calls, look-up, report and file complaints for nuisance or scam call numbers. For an additional 99p per month, once their free trial expires, users can effectively block any unwanted calls by diverting them direct to voicemail, with greater call filtering customisation, and the ability to create a custom Approved List and Blocked List.
