I have been very happy with Mint in the USA but as I note in a reply thread below, it is useless for international travel. Use an ESIM app instead. On my latest trip to Europe it worked for about 5 minutes upon landing and then I got kicked off the network and it never worked again. Simultaneously, my login in the Mint app was invalidated... and I cannot login now via any channel. I use a password manager so it is not user error. I'm back home now but the login issue persists and I have a ticket open for it. I can get only get into my account if I follow this path:

• go to mintmobile.com and hit login
• click send password
• receive one-time verification code by SMS and enter that
• when prompted I enter my one-password from my Authenticator
• when prompted I pick a new password and press enter

Once I do that I drop into my account, authenticated. If I log out again, the new credentials never work.

I have to wonder if I tripped some sort of fraud control in Europe.
