Telecom giant Vodafone Idea has recently started sending warning against picking up any calls from unknown international numbers. The company issued the warning through SMSes to its users which is different from the usual approach of issuing warnings with the help of automated calls. Considering that the company is sending this message out to all the Vodafone Idea customers, it is likely that there is some threat associated with these calls. It is also possible that the company may already have received a number of complaints regarding such calls that it is issuing a widespread warning.
According to a report by TelecomTalk, the message sent out by the company to its users reads, “While receiving an international call, if an Indian number or no number us displayed on your phone, please inform on toll-free number 1800-110-420 or 1963.” We also received a similar message from the company which stated, “Priye Grahak, Antarrashtriya call receive karte samay yadi phone per bhartiya ya NO number display ho toh iski jankari tollfree nos 1800110420 ya 1963 per dein”. It is likely that the company is planning to crowd-source the suspicious mobile numbers and then block them from their end but the company has not revealed any details about any such plan.

The report also noted that the two helpline numbers mentioned in the message are the lines that TRAI introduced last year. These helplines are introduced to make the process of reporting suspicious calls and messages directly to the regulator. It is possible that the person or set of people behind these calls are using VoIP-based technology to make these calls.
It is worth noting that these warnings are nothing new and telecom operators have time and again issued warning against any unknown numbers because it is difficult to identify and trace the culprits that are using VoIP-based software to make such calls. Users should practice caution and install caller ID-based apps such as Trucecaller to ensure that they can find who is calling before picking up the call.
