The much awaited and promised voice calling feature has finally been rolled out by mobile messaging service ********. But this feature will be accessible to only select users in the country and will be available on an invite basis. The invite-only basis basically means that users will get a call through ******** from someone who already has the feature updated. The feature is also restricted to Android only and you will need the updated 2.11.508 version to access the app. He further informed that a person who has got this feature working needs to call another person to perhaps tag team it further. “Its like an invite thing, where a person with the call feature needs to “call” another person who wants to start using the feature,” he said.
