- Using Free Zone you can access many internet services free of cost(no charge for data).

- Available on most internet-enabled mobile phones on default Browser(no 3rd party browser)

- You can use Free Zone even if you haven’t subscribed to a data plan with your operator.

- Before you are charged, you will see a notification page. If you don’t already have a data plan, you will be given the opportunity to sign up for one.

- Whenever it is Green, you can surf free of cost, when it turns Red billing will start ie, your data plan comes in picture there.

- Viewing mail attachment is charged.

- No charge for Google search, even you can go to the website shown on the search page without being charged. But if you clicked on any link there, then pricing will come in picture.

example : if you click on a search link to a Wikipedia article, you won’t pay anything. But if you click on a link within the article, you will be charged for the data costs incurred loading that link. Also, you will be warned before being charged.
