They very much hide which roaming packages auto-activate IMMEDIATELY without asking the moment you purchase it. It's not roaming once you touch the new country...it's roaming from the moment the payment is completed. And of course buying at the airport once landed it's a pain. Terrible behavior for any roaming packages. It only shows the specifics if you tap the minuscule 'i' icon. It should be in a red text warning forefront.

This app has helpful features but has lots of technical issues. Sometimes it does even open. Sometimes it doesn't even send otp msg. Lots of other issues. I have been trying to log in since yesterday but still not successful. The oyp they sent me keeps saying its wrong. After severals atteps it asked me to try again after 24 hours.

The application works really poorly-it is sometimes impossible to run it for many hours, even days, as it crashes already at the level of start screen. Also, it requires one time password each time you log, quite unnecessary in my opinion.
