Malicious / Nuisance Calls & Texts.

Nuisance Communications - Scam Calls and Text Messages

Nuisance calls and texts are in one word, frustrating. They can lead to unnecessary stress and anxiety, especially if you have fallen victim to these fraudulent communications. Tesco Mobile is fully committed to doing everything within our power, to implement interventions to protect you from these nuisance communications. You may already have noticed a decline in such scam calls or texts, as a number of interventions have been implemented across the industry. We will continually work with the authorities, government bodies including regulatory taskforces and Irish service providers to protect our customers from fraudulent communications.

SENDERID REGISTRY

ComReg has launched an SMS Sender ID Registry to help prevent scam SMS messages. Only alphanumeric Sender IDs must be registered e.g., TescoMobile. Only those SENDERID registered will be delivered to customers.

Tesco Mobile will only send you SMS messages using the following SENDERID's:

TescoMobile or TMVoicemail

From 3 July 2025, unregistered SMS Sender IDs will be modified to 'Likely Scam' to alert the recipient to be cautious of the content of those SMS text messages.

From 3 October 2025, SMS text messages from unregistered SMS Sender IDs will be blocked and those messages will not reach the recipient.

Prevalent scams:

Phishing is where scammers trick you into giving sensitive or commercial information or performing harmful actions through deceptive emails, messages, or websites.
SMShing is when scammers send SMS (text) messages and it looks like it is from a legitimate company, such as a delivery service. It tries to trick people into giving away personal information or clicking on links which could install malicious software (malware) on your phone.
Vishing is when scammers try to trick people into giving away personal or financial information over the phone. They might pretend to be from a bank or government agency to get your passwords, credit card numbers, or social security info.
Number spoofing is when scammers call you, and they display an Irish number (caller ID) so that you think it is a legitimate call, coming from a trusted Irish number.

Top Tips

Be vigilant and never give out your personal details.
Report to the Gardai. The making of malicious and nuisance calls is a criminal offence.
Don't click on any links, unless you are certain of the source. If you have any doubts, contact the company directly.
Be wary of receiving multiple calls or missed calls from the same unfamiliar number. Do not call back any number that you do not recognise or where no voicemail message was left.
Check messages and links for spelling errors or incorrect details.
