Smartphones are at the top of the consumer dream of many Brazilians. There are currently around 230 million active devices in Brazil — according to data from a survey by the Fundação Getúlio Vargas — which means more than one unit per inhabitant. Even so, with technology advancing, it is imperative that people always want a newer model. At the same time, prices are rising and the dream of a new device is becoming distant. This opens the door to a dangerous modality: devices not approved by the National Telecommunications Agency (Anatel). That's why it's important, when buying, to look for a certified device. qs15
At first glance, they may seem advantageous because they have lower prices. However, they are a big trap. Not just for the consumer, but for the entire communication system in the country. Cell phones and smartphones are the most visible edge of the problem, but this also applies to modems, tablets, trackers, baby monitors, notebooks, wireless microphones, wireless mice and a host of other devices.
What are the risks? 6u2u4d

A cell phone – or any other device – certified by Anatel guarantees that you, the consumer, are safe. When it comes to a device certified by Anatel, it means that the product meets all quality requirements and, especially, health protection. Imagine that a device that does not meet these same criteria may not only be incompatible with Brazilian networks, but may also put your health at risk.
Since 2018, the program Cool Cell Phone Anatel has a computerized system that aims to identify non-certified devices and, in this way, prevent them from being used in the cellular network. Devices used before this date remain active, but cannot change their number. Hence the importance of making sure that your device is certified by Anatel.
While prices may be more affordable, the risks of losses are incalculable. Pirate cell phones leave the consumer unprotected, as they have no guarantee. So if there are any technical issues, there are no official channels to turn to.
As already mentioned, another major risk concerns health. To be approved by Anatel, the device must use materials and radiofrequency transmitters that meet international quality standards that, consequently, protect the health of the consumer. To give you an idea, non-certified devices do not undergo tests that assess electrical safety and limits for exposure to magnetic fields and may even interfere with the proper functioning of the telephone network. It is good to that irregular devices can expose the to inadequate levels of radiation as well.
How to know if the device is certified? 4u2633
It is very important that, at the time of purchase, you demand not only the invoice, but also that the purchased product has the Anatel approval seal. The Anatel seal is your only guarantee that what you are buying is equipment that complies with all the standards established in Brazil.

Current rules state that, in order to be used in the country, the device must be homologated. This is also true for any equipment that uses radio frequency — which goes far beyond smartphones, including cordless phones, modems, tablets, trackers, baby monitors, notebooks, wireless microphones, wireless mice and a range of things that are part of our day by day.
Device without certification, what to do? 6203n
If by chance you acquire or come across a device not approved by Anatel, the Consumer Defense Code protects you. Having purchased the product with an invoice, it is possible to return the irregular device.
If the device is not new, you can check the IMEI to find out if it is theft or if there is any other type of irregularity, such as not having Anatel approval or having been tampered with. To make a query, you need to access the Anatel website.
