This app doesn’t work unless you (presumable) own a Turkish phone number. It oddly can’t be used after downloading from Apple Store (even though that itself connects to your identity/apple ID, normally, and your selected payment method). You are asked to register, same as on Mobilet website. And this can only be done after putting in a verification code that, however, never arrives. Take it from me, I’ve tried. And tried again. Various devices, browsers, this app. No luck. I read about the same result in the only other review here. They mentioned RU number; my number is CZ, the EU. And on Trip Advisor someone from Tel Aviv had the same story to tell. I’ve already emailed their support, and the venue’s info email. If they either fix the issue or advise an alternative solution, I’ll be happy to edit this review.
