Not the world but yes this idea is going to change your attention on other cellular because it give more than full network yes .
I have been using it more than 5 year and did not have any complain about it.
The best thing is that you can get idea network any were which is the most recommended things of the user also the customer service is good.
The worst thing is only that its recharge pack is slightly greater or nearly equal but it is an average if they reduces it will be more suitable network if we talk about the site it is also an average like other no difference seems.
