Apple announced on Tuesday (15) the new Apple Watch Series 6 and Apple Watch SE, and there is a surprise: for the first time, models with cellular connectivity (LTE) will be compatible with the 700 MHz frequency used in Brazil (band 28), something that was not available in past generations.
In Brazil, the bands used in 4G are 1 (2,100 MHz), 3 (1,800 MHz), 5 (850 MHz), 7 (2,600 MHz) and 28 (700 MHz APT). All of them are available on the Apple Watch Series 6 and Apple Watch SE for the European and Asian market, which must also be sold in the national territory (models A2375, A2376, A2355 and A2356).
The 700 MHz band is important for having higher signal penetration and allows better operation indoors. At the same time, lower frequencies deliver lower speeds, in addition to serving fewer users connected to the same tower.
US Apple Watch does not work with 700 MHz
Whoever buys the new Apple Watch Series 6 or Apple Watch SE in the United States, Canada and Mexico will be without connectivity with the 700 MHz band and will be served by 3G and 4G on other frequencies. The same occurs with the North American iPhone 11, iPhone 11 Pro and iPhone 11 Pro Max.
In practice, it is impossible to say that the product will not work in Brazil, since Apple Watches from previous generations did not support the band 28 and were marketed and used in the country. The operators Claro, TIM and Vivo also operate with other frequencies, while Oi and other virtual mobile operators (MVNOs) do not offer the connectivity service for the smartwatch.
Due to its higher signal penetration, the frequency of 700 MHz is used exclusively by some operators on roads or small towns, which reduces costs in the implementation of the network. Anyone using an American Apple Watch in a location like this will be without 4G connectivity service.
However, those who stay in the big cities need not worry so much: the other bands continue to work and will not be turned off anytime soon, since the operators act with aggregation of frequencies to deliver greater speed in 4G.
