iPhone Downgrade from 13.3 to 13.1.3

[cavi]

Hello,

I bought new Apple Watch S5 with cellular connectivity in the US. Since I'm located outside the US, I was told that I need the European model in order to activate the cellular feature.
I tried to contact apple for a replacement, but no answer yet (they told me that I can return the watch to the Apple store in the US, but I'm not located in the US...).
I understood that although I have the US model (A2095), I can activate the cellular feature with iOS 13.1.3. My iPhone is running 13.3. My question is how can I downgrade to iOS 13.1.3 from iOS 13.3?

Thanks a lot =]

iOS version doesn’t matter. Cellular won’t work.

I understand, but there’re people who (claim) that they succeed by running 13.1.3. How? I don’t know, but I want to try

You can’t downgrade.

iOS 13.1.3 is no longer being signed by Apple, there is no way to downgrade.

The only way to “downgrade” at this point is to purchase old stock (new phones) until you *maybe* get a device with an old software version on it.

Other than that it is not possible.

It would be infinitely cheaper to sell the watch for what you can sell it for, buy a compatible model, and cut your losses.
