It’s not clear if eSIMs are compatible.

I’m a T-Mobile Postpaid customer using an iPhone 11 Pro Max running the latest version of iOS, but I am unable to have the app get past the device authentication step. After the privacy statement, I see “Device Authentication Error.” Is this application unable to detect my eSIM? I’m using my physical SIM card slot for an international cellular account, so I can’t use Zenkey unless it is compatible with iPhone eSIM cards. Unfortunately, I was unable to certify in any of the documentation or FAQs whether or not this is the case. Is it possible? Seems like a glaring error, if not.

fail on initial login

So I'm supposed to be able to use my T-Mobile login, since there's the partnership, but it returns an error and just says to call the carrier. HUGE FAIL. Uninstalling useless-out-the-door garbage. If I WANTED to call and sit on hold to wait for someone else to do the exact same thing I should be able to do myself because I'm not computer illiterate, I would have done that. Now I've wasted my time trying to use a useless app, but this review is time well spent to warn others not to waste their time on this trash. YOU ARE THE WEAKEST LINK. GOODBYE.
