Scam Alert: Impersonation of M1 Staff

We have received reports of phishing scams involving individuals impersonating M1 staff. These scammers would claim that victims have signed up for device contracts, and direct victims to a fake WhatsApp chatbot which displays a fraudulent M1 contract. Subsequently, victims would be asked to provide banking details and to transfer funds to the scammer’s account.

 

Stay Safe:

  • M1 and government agencies will never ask for your banking details, passwords, or to install apps from unofficial sources.
  • M1 uses WhatsApp for selected services and customer interactions. Our official business account is marked with a “Meta Verified” blue checkmark next to the name. This verification ensures you are engaging with the legitimate M1 account, not a scammer.
  • Do not transfer money or hand over valuables to unknown individuals.
  • Verify all suspicious communications before responding.

 

What You Can Do:

  • Enable notifications on the My M1+ App to receive scam alerts
  • Call ScamShield at 1799 or the Police hotline at 1800-255-0000 if in doubt.

Scam Alert: Calls and WhatsApp Impersonation of M1 Customer Service

We have been alerted to scam attempts involving Voice calls, WhatsApp calls and messages impersonating M1 Customer Service. Scammers may even use fake contracts or pressure individuals with threats of high monthly charges.

Please note:

  • M1 does not send contracts via WhatsApp.
  • Service termination is only processed through our official hotline at 1627.
  • Any requests via WhatsApp are fraudulent.
  • Legitimate incoming M1 calls will only display these caller IDs: 1622, 1627, 1623 or 1693. 

Do not click suspicious links, open unknown attachments, or share your personal details with unverified sources. Stay alert when handling emails, SMSes, or calls from unknown contacts.

We’ve been alerted that some customers have received phone calls from scammers impersonating M1 staff. These scammers would ask for the customers’ credit card or banking details on the pretext that their mobile lines will be suspended due to non-payment.

Please note that M1 does not call our customers to request for credit card or banking details, and we strongly urge customers to be vigilant against such phone scams.  M1 customers can access the status of their bill payments and pay their outstanding balances through the M1+App.

2 Jan 2024: We’ve been alerted to a “M1 customer reward program” on social media where customers can win phones or gift cards by answering a questionnaire. This programme is not conducted by M1, and we strongly urge our customers not to participate as it is possibly an unlawful attempt to phish for their personal information.

We have been alerted that there is a website impersonating the M1 login page. This is likely an attempt to phish for our customers’ login details and other personal information. Customers are encouraged to log onto their M1 account through this main page (https://www.m1.com.sg/), and to exercise caution of links sent through emails, SMS or posted online as some links may be fraudulent and lead to malicious websites.

Description:

As part of Infocomm Media Development Authority’s efforts to strengthen protection against scams, registration with the Singapore SMS Sender ID Registry (“SSIR”) will be mandatory for all organisations that use SMS Sender IDs. With effect from 31 January 2023, under SSIR, all non-registered alphanumeric Sender IDs and SMS will be marked as “Likely-SCAM” when sent to Singapore mobile users. This functions similarly to a “spam filter and spam bin”.

We urge customers to remain vigilant against ongoing scams and look out for our SMS advisory to alert customers on the “Likely-SCAM” SMSes they may receive.
