Systmyze
Got the solution, in my case the culprit was the “Validity Expired Second SIM” inside my NP1. I wondered before the update there was no such problem.
Anyway, here is the trick, In the “SIMs” settings,
1. I have to enable the second sim (which was auto disabled after the recent update, I don’t know why).
2. then selected “Get started” from the “Set your SIM preferences”.
3. Tap “Next” > select “Mobile data” > selected the working sim > Done
Now, “Internet Data” is working & showing up but the second SIM is still disabled by the phone.
