Given that the app is highly popular in India (Truecaller: More than 1 millions Indians are using the phone directory app), the company has partnered with Innoz for SMS search.
The syntax is very simple:
SMS TRACE <10 Digit Mobile No> to 55444. Eg Trace 1234567890.
The SMS is charged at Rs. 1/query.
The user will then get an immediate response with all details including the name, service provider and service region.
Truecaller is a collaborative global phone directory app that has been in existence since 2009. The Swedish app has quickly gained popularity in countries where public phone directory data is scarce or non-existing. In March this year, it announced that it had more than 13 million users worldwide who were conducting over half a billion name and number searches each month.
One could search the global directory online and also use the mobile apps across all platforms to figure out who is calling from an unknown number. The mobile app also lets you block certain numbers.
The app uploads users’ phone books (with permission) and makes them part of its crowd-sourced database which caused privacy concerns.
In May, Truecaller had opened up its to a select group of “handpicked” developers in a means to monetize its database.
The popularity of using SMS services like 55444 to provide Internet based services is growing. Just last week MakemyTrip teamed up with txtWeb to offer customers the ability to book bus tickets by SMS and also the Indian Railways also launched SMS based ticket booking.
How to: Unlist Yourself from Truecaller
Given that Truecaller uploads the phone books automatically it is a cause of worry for many. The likelihood of your number being listed on Truecaller is very high because many users have chosen to share their phone book with it. So if you are someone who is concerned with privacy we recommend unlisting yourself by going to the Truecaller website and entering your phone number which will remove it from the directories instantly and permanently.
