There is no specific instructions because each use-case & user experience is different based on network provider, SIM type (physical SIM or eSIM), user location (what country or state), Kompakt model (Global or NAM), as well as what previous phone a user is switching from- whether it’s Android based or an iPhone (or something completely different). There’s just too many variables.
Additionally, sometimes, there’s something that’s happening ‘under the hood’ and our team needs to look at the phone logs.
That said, we are working on a separate page with the most common cases, to make this process smoother.
In the meantime, you can check out this post that another user posted about the steps they took:
