}FAQ
Common questions
When should travellers install the eSIM?
Before departure, while they are still connected at home, so the plan is ready when they land.
Which phones support eSIM?
The traveller’s phone must support eSIM and be unlocked. A compatibility reminder in your checkout avoids most support questions.
Can we add other products later?
Yes. Every Avunzo product uses the same authentication, conventions and booking lifecycle, so adding a product does not mean starting a new integration.
Can we apply our own markup?
Yes. You set your own markups and present results in your own customer or agent experience.
