Well, I found that Brasil has a digital CRNM for foreigners. I can't speak to android but for the iPhone, it's basically impossible to install - because you have to have your AppleID set up to be Brasilian.
My AppleID is US based and I have a number of subscriptions. If I change my account to Brasil I lose all my subscriptions. Now, I've been told I can create another AppleID and base it in Brasil, so I would have to log in and out between accounts every time I wanted to use the digital CRNM. I suppose that wouldn't be too bad, but just seems like an unnecessary hassle.
Why on earth would Brasil make a digital CRNM for foreigners and only restrict it to be used by Brasilian based accounts. The whole reason you have a CRNM is that you are a foreigner. Chances are you're already going to have a whole history of purchases, etc. with your existing mobile phone. Me thinks this is just an Apple issue, where they want you to pay with a Brasilian bank account or credit card or some such nonsense - but the CRNM app is free, so who knows.
If anyone else has any other ideas on how to easily get this working, I'd like to hear it, but for me at least it isn't worth the hassle of having and maintaining 2 AppleIDs.
LOL… that was my rant for today!
