Truth –

Although SIM swap farud is a serious threat and have affected many and yes it can drain your bank account but just pressing “1” can’t do it.

One need to place a Network Jammer in your physical neighborhood, rather in your house to bring your network down to Zero unless it’s some real Celluar service provider or natural problem.

Plus, just by pressing “1” one can’t access your phone.

News Paper Asian Age reports

“MUMBAI: Mumbai has seen a rise of around 3,000 complaints against ‘SIM-swap’ fraud in the first four months of the year, which involves a caller acquiring details related to a debit or credit card to steal money. The figure of cases from January to April this year came to about 20,351 cases, whereas last year’s corresponding figure was 17,724. The police is working on sending notices to telecom companies to put up better firewalls, which can stop the cases of SIM swaps.

Explaining the scamsters’ modus operandi, an official from the cyber police said, “The scam is operated at three levels.

At the first level, the mastermind targets the victims and gets hold of their phone details from the company.

At the second level, the accused collects bank details and identity proof of the victim.

Then at the third level, the accused executes the plan, and sends messages of various fake transactions of the bank, giving victims the impression that their card has been misused. Following this, the accused calls the victim impersonating the mobile company employee, and get details like the Personal Identification Number (PIN) and Card Verification Value (CVV).”

According to the data procured by The Asian Age, the numbers of cases of SIM swaps have gone up quite significantly showing a rise in the trend. In the whole of 2017, about 31,674 such cases were registered. In this type of scam, a criminal registers an existing number of a cellular company’s client on a new SIM card.”

It’s all about CVV printed on backside of your card or giving out your OTP which you shouldn’t in any case. Through phishing mails or calls pretending to be from Banks etc, they try to get your personal info with which they can get a new SIM card issued which was has your number and start getting OTPs. Yes, as soon as the company issue another SIM card, your mobile’s network will become Zero “No Service” as your SIM card won’t be active anymore.
