Mobile operator Three Ireland has said that it blocked more than 26 million suspected scam calls and intercepted over 455,000 fraudulent SMS messages in 2025.

So far in 2026, Three said its fraud team has already blocked over 4 million scam calls and intercepted more than 650,000 fraudulent text messages.

The company said the figures reflect a broader, industry-wide challenge, with fraudsters continuously evolving their tactics to target customers through both phone calls and text messages.

With fraud activity typically increasing during the summer months, Three Ireland is urging customers to remain vigilant.

On a single day alone, Friday 8 May, more than 27,000 scam calls were blocked on Three's network alone, while over 5,000 suspicious calls were flagged to customers with a "possible scam" warning.

The company said there is a growing shift towards more sophisticated call-based and social engineering scams, where fraudsters attempt to manipulate customers into sharing sensitive information in real time.

"While we intercept large volumes of suspicious activity, vigilance remains key," said Tom Kinsella, Chief Consumer Officer at Three Ireland.

"Customers should always be cautious of unexpected calls or messages and never share personal or account information, including one-time security codes," Mr Kinsella said.
