I actively have 2 sim cards, under Calls and Messages, I can select either sim card but with Mobile Data, I only have sim 1 available and sim 2 says "Off"
I used to not have this kind of problem before and I badly need the second sim card for additional mobile data.
Unfortunately that is not the case. The signal just dropped when the screenshot was taken. Aside from that, there is no problem with Calls and Messages on Sim 2, just the mobile data. It simply says Off as the second option whereas it used to say the second provider. So no, the signal on the screenshot is irrelevant
