From a sim card set of instructions that I was working with today: For iPhone customers: Please install APN after inserting sim card. Open the following website with Safari-Browser: *.*.com.

That isn't just working. It looks like iPhone users have an extra configuration step when using this particular sim card.

I’ve never seen that before and am interested. Can you post a link to those instructions?

Sure thing. https://imgur.com/a/GsLYW6W The specific instructions for iPhone users are at the very bottom.

Thanks! Very interesting. I suspect this has something to do with the network arrangements of simcard-korea. That’s not standard for iphones with ‘normal’ in-country sims. I change my sim every few months and it ‘just works’ without any extra steps.

I think the app is just for you to check your data usage. Things will work without it. Just insert the SIM card and reboot.

The link at the bottom has a profile that sets the APN - it might work without it if you reboot tbh but without being in Korea and having the SIM I can’t verify that. It isn’t the app that he’s talking about.

Didn’t see that. Viewed image on phone and didn’t scroll.

I think it depends on the carrier whether APNs are required. Can be automatically set nowadays with iOS 16 according to https://support.apple.com/en-us/HT201699

I don’t think I’ve _ever_ had to manually set my APN though. I’m now more confused after seeing your link!
