With more than 100 million users, Truecaller offers its services in more than 200 countries.

The company in a statement said, "India is the number one market with more than half the users in the country."

Now the company is looking to entirely replace the native dial pad app on Android devices with significant improvements that make the experience faster, smarter, and more convenient.

"The new Truedialer app includes a more intuitive app design, expanded search, and improved dual SIM support across more than 500 Android devices, allowing millions of handset customers to easily switch SIM cards in order to access the best rates for calling and data traffic," the statement said.

"Supporting Dual SIM devices is not a matter of choice for us, it's a central part of the phone experience for our users," said Nami Zarringhalam, co-founder and Chief Strategy Officer at Truecaller.

"With every new release, we are taking one step closer to making Truedialer a complete replacement of your default dialer and we look forward to expanding our relationships with OEMs and operators to meet the growing demands of our users globally," he added.
