APN settings on dual nano sim iphone (model A2412)?
I have a dual nano sim iPhone 12 Pro max (model A2412), and want to see / change the data APN settings, but the instructions from the single sim model don't work. I receive calls and texts perfectly fine on both lines but my data isn't working and I want to see if there's any issue with the settings.
How do I access the APN settings on this model?
