Not worth the hassle
Wow evey step of the way trying to get the esim activated there were issues. And you cannot activaye early as you can only activate upon arrival. Better of buying a physical sim at the airport

We’re sorry to hear about your experience and appreciate your feedback.
Our eSIMs are designed to activate upon arrival to ensure full validity during your travel period. While most activations are smooth, we regret that you faced issues along the way.
We’re continuously working to improve the activation experience and appreciate you sharing your thoughts.

Some of the worst customer service - more than 24hours for esim activation!
Some of the worst customer service. Purchased an esim and it took more than 24hours for them to sort out the activation. Every time I message or call them, it's the standard reply that their team is working on it and will be done in the next 2-3hours. Keeps repeating the same thing over and over again! Can't even bloody cancel my order as they just ignored my request and continue to ask me to wait.
