The Policia Nacional has issued a fraud warning over scammers posing as internet company DIGI and telling customers their routers needed replacing.

The callers claim that DIGI previously sent the customer a notification through its app but that the message has since disappeared.

Police said this explanation is a warning sign designed to prevent the victim from checking whether the communication is genuine.

Another major red flag is that the caller does not know the customer’s name.

‘If you are a DIGI customer, they know your name and surname,’ the force warned as part of its #NoPiques anti-fraud campaign.

How to recognise the scam

Fraudsters frequently impersonate internet or mobile providers to obtain personal information, banking details, account passwords or security codes.

They may also attempt to arrange a fake technician’s visit, persuade the victim to install remote-access software or use the promised router replacement to obtain a payment.

Anyone receiving such a call should avoid confirming personal information, clicking links or providing passwords, bank details or SMS verification codes.

Do not rely on a telephone number or website supplied by the caller.

Instead, end the conversation and contact DIGI independently through the telephone number displayed on its official website, app or an existing bill.

The Policia Nacional stressed that DIGI communicates with its customers through its recognised official channels.

Customers should also be suspicious of callers creating urgency, claiming an immediate equipment change is necessary or warning that service will be disconnected unless instructions are followed.
