Recently I noticed my phone does not show the 'Yes optus' & 'VolTE' icons on the left side of the networking bars, and there is a 'no service' on the left of the bars. But strangely, the 4G sign is there, calling has no problem, sending & receiving messages are fine, browsing internet is fine, downloading is ok.
have you experienced the same issue? I'm using HUAWEI P30PRO.
Not sure why you posted this 3 times.
P30 pro is a dual sim phone.
Meaning you can put in 2 different sim cards at the same time.
So what your seeing is the second sim card slot not activate as you only have 1 sim.
