I bought NP2 the day it was launched. I had been facing this captioned issue for the past 6 months. It was more frequent in Dec ,2023 and also very often subsequently. Suddenly the signal goes off and shows Emergency calls only, I need to toggle airplane mode on and off continuously and then the signal comes back. Worst part is when my family tries to reach me, when my office contacts me, this is really annoying. I complained many times , raised tickets but to no avail. This is an attempt atleast through the community personnel i would be reached to the concerned team and this issue will be solved.
