Last week, we explained that the A1920 and A1921 models (iPhones XS and XS Max, respectively), sold in the United States, do not support the band 28 (700MHz APT) of 4G / LTE. Does this mean that they will not work here in Brazil, that they will not be able to connect to Brazilian 4G networks? Not quite. They will work, yes, since much of the current 4G signal uses the band 7 (of 2,600MHz).
It so happens that, with the release of band 28 (thanks to the death of the analogue signal from TVs), this frequency of 700MHz APT started to be used also by some operators, in order to expand and improve the coverage of the 4G network in our country. The trend that bandwidth 28 usage increases and the problem is: as the American XS and Xs Max iPhones do not support this frequency, it may be that in some cities or regions you may not be able to get the best 4G signal. Therefore, the most recommended (for those who can, of course) purchase the model A2097 (XS) or the A2101 (XS Max), sold in European and Asian countries.
Apple itself has already confirmed that the models A2097 and A2101 will be the ones sold here in Brazil, since the specifications page of the iPhones XS and XS Max contains precisely such models.
And the iPhone XR?
All that we talked about related to the iPhones XS and XS Max. But what about the iPhone XR? Does the 6.1 ? model that will be launched by Apple at the end of October follow this same path? Yes.
On the page that lists the countries and the respective models of iPhones that will be marketed in each of them, we still have no mention of the iPhone XR. However, on the phone's specification page, Apple lists the model A2105 which is different from the model listed on the American page, the A1984.
This scenario was already almost certain, but now it is confirmed. Obviously, just like the iPhones XS and XS Max, the iPhone XR purchased in the USA will work in Brazil, but it will have this limitation of connecting to 4G networks when a certain operator works only on the frequency of 700MHz APT (band 28) in a given city or regal.
it is good to note that no operator will simply stop supporting band 7 (of 2,600MHz) in the short term. A lot of money was invested to build the Brazilian 4G and, currently, the expansion of band 28 (700MHz APT) is "in its initial phase". Although it is more interesting because it offers greater signal penetration (overcoming obstacles such as walls and improving indoor coverage) and because it has a greater reach, nothing in this technology market happens overnight. No wonder that the 2G / EDGE signal is still operational today.
Of course, the best of all worlds will have a device that supports two bands, so you don?t have to worry about it. But, again: purchasing an iPhone XS, XS Max or XR in the USA does not mean that you will not connect to 4G networks here in Brazil. And, regardless of that, have full warranty in Brazil and can even exchange it for a national model in case of defect, who knows.
