Unreliable!

That is so unreliable app, I don’t recommend. When you need the connection most, it doesn’t work. No any prior warnings! The latest example is that the UAE was included in the list of supported countries just 2 weeks ago, no when i arrive i found out that UAE is no more supported!

Cannot contact support

New iPhone and I can’t download a new esim. My profile says eSIM installed but it is not installed. On the contact support page I can get through the steps but after downloading a screenshot there is no option to send.

Worst app ever

Tried to install esim and got stuck. Tried to contact support. App has dark patterns all over so you can never reach support. Lost my $20 purchase
