Anyone has any idea why my phone always prefers B40, which sucks because I am in that zone where B40 cannot work due to signal degradation but my phone loves to latch and lock to it in clear weather conditions. As soon as it rains, B40 degrades so much that my phone automatically jumps to B3 and the Internet is working well. I have Jio behaving like this btw. I use another phone, which doesn’t support B40 and Jio works flawlessly. So my theory is Jio should really signal phones better to switch away from B40 at less than optimal signal quality. B40 is feasible only for the ones closest to the tower.
