It is not today that Brazilian operators agree with exclusive products to offer unlimited services. We have, in this case, Claro that offers (not very clearly) unlimited data for access to Facebook and Twitter. This means that if you access these two social networks, the data will not be discounted from your franchise.
In these same molds, TIM launched last week the Whatsapp ControlThat's exactly what you're thinking. With a partnership signed with the product, TIM offers unlimited data to customers of this plan for use in Whatsapp. You can send videos, photos, voice messages, text and anything you want through the app, without taking it out of your data package. The most interesting thing about this is that the service continues to work even after you blow up your data franchise.
In addition to unlimited Whatsapp, the plan has 300 MB of internet franchise, unlimited torpedoes for any operator (even without credits) and more R$ 10.00 credit to be used as you wish. All this for the promotional value of R$ 29.90 which, after 20 February 2015, will pass to R$ 34.90.
It is worth remembering that the 300 MB franchise is for routine internet use, such as reading emails, searching, accessing social networks, etc. After its consumption, the mobile internet stops working, leaving only Whatsapp as an exclusive service. If you need more internet, you can choose 10 MB per R daily packages$ 0.75 on the day you use, or by renewing the 300 MB package per R$ 14,90.
We can note that this is the end of unlimited internet with reduced speed in Brazilian operators. After Vivo, Claro and Oi announced the data cut by reaching the limit of the plan, it was time for TIM to renew its services.
