The cell phones of 4 chips are the newest sensation among lovers of next-generation cell phones. This phone carries the 4 chips simultaneously, i.e. it is possible to have a chip of each carrier (let's say TIM, Vivo, Claro and Oi) operating at the same time on your mobile. This could mean a great savings because in addition the bonus and promotions that each carrier offers, in addition to free or cheaper calls to mobiles in the same carrier, you're probably not more pay a high cell phone bill. That's the big advantage, besides the guarantee coverage, of course. The downside is that the battery tends to last less, because they are 4 chips activated at the same time. Another disadvantage is that there are only 4 cellular chips to Chinese brands, proven to be more fragile and without warranty. But if you bet at this novelty, to avoid problems of sending products coming directly from China buy with a seller in Brazil that already have these products in stock, as registered sellers on eBay.
