There is debate of sorts going on that many 5G mobile phones being rolled out these days may not work the moment your network provider rolls out a 5G network in your area.
Well, there is good news. The n78 band which is also referred to as the 3500 MHz or the 3.5 GHz band, and is also known as the C-band 5G is the most popular 5G band. This popularity stems from the fact that it offers good speed, great coverage and to top that, it also is most commonly available.
It is certain that Telecom operators in India will roll out this band.
OnePlus 9 series, Mi mobile phones etc. in India supports either of these bands – n41, n77, n78. In other words, the moment your network provider rolls out a 5G network in your area; your Device can access it! This is confirmed by The Indian Express in detail.
