What the above say

Claro sought TechTudo after the story was aired. In the face of consumer protests, the operator sent the following note:

"Claro informs that only the data traffic proactively used by the customer is charged or deducted from the franchise. Therefore, there is no charge if you disable the smartphone connection. "

In a statement, Oi claims to take steps to ensure that the consumer is not affected by data traffic, which is considered to be "inherent" to 4G. Look:

"This small involuntary data traffic, observed even when the user deactivates the data option on their handset, is an inherent feature of 4G technology. Oi has internal mechanisms to handle this traffic, preventing the customer from being harmed in any way. "

Vivo acknowledges that charging can occur on both Android phones and iPhones. Check out the company's clarification:

"Daily internet charging can happen in 4G terminals, or with the 4G function enabled. This is due to the specificity of most smartphones that, even after the mobile network is deactivated, does not end the consumption in its entirety, maintaining a small exchange of traffic (bytes) of control between the terminal and the network of the operator. In 3G mode, when the terminals have the mobile data option disabled, the connection is completely disabled, with no data traffic between the network and the client terminal. Vivo, since the beginning of the year, has discarded the first 100 Kb / s of all customers, regardless of whether the device is 3G or 4G. "
