The Communications Regulator ComReg has issued a warning about romance fraud ahead of St Valentine’s Day.
The regulator said the scams typically involve fraudsters creating fake identities to form emotional connections initially through dating apps, before making contact directly by texts or calls.
The ultimate goal is to trick victims into sending money or financial information.
Once trust is gained, the fraudsters create reasons to ask for money.
"These scams can have significant financial and emotional impacts," ComReg said.
"They often originate from overseas but also occur domestically," the regulator added.
According to ComReg, the full extent of these scams is unclear, as many victims hesitate to report them to Gardaí.
Consumers are being urged to be cautious of calls or texts urging them to act in haste.
People should also be wary of texts from unknown numbers, avoid clicking on suspicious links and never share personal information.
"If you suspect you have provided financial information to a scam or experienced identity theft, contact your bank immediately to seek advice and potentially hold your account," ComReg said.
"Report the incident to any Garda station, where your report will be treated confidentially," it added.
