Software required for iPhone 6

[wpalascak]

The visible mobile app requires ios 15.4 or greater. My iPhone 6 says it’s software is up to date but is only iOS 12.5.7. How do I overcome this hurdle?

I think the only way around it is to buy a new phone.

You can utilize the website for all your needs. The app is only required to make eSIM transfers seem less. There isn’t anything that the app does that you can do online. The website is formatted perfect for mobile use. You don’t have access to any additional features in the app.

I don't think it's possible to activate a SIM card using the website. I believe it can only be activated using the app.
