I was outdoors one day and saw a weird symbol on my phone. My dual sim phone was showing this symbol:
Normally it'd just show up as volte/4g/5g.
Looking further, this is actually telling you that sim 2 had no network connection, BUT it's piggybacking from sim 1.
From what I've read, Auto Data switching must be turned on.
Didn't know about this until recently!
