This time our friends from United Mobile have put a lot of efforts to hide their identity.
That NAKA AG in Buchs (coincidentially located just next to Liechtenstein) is registered with the Swiss company register as a branch (see
http://www.moneyhouse.ch/u/a/naka_ag....073.864-2.htm) of NAKA AG located in Sirnach (Thurgau) (see:
http://www.moneyhouse.ch/u/naka_ag_C....026.773-4.htm). NAKA AG is managed and officially owned by two nominees, namely by a lady called
Antia Eugster and
Christoph Reuss, both employees of an escrow agent company called Thalmann Treuhand AG.
Against this background and given the track record of the people behind United Mobile and the also failed attempt of at least one of them (Cornelis Swart) with FreeTimeTelecom you should definitely think twice before getting a Swiss Mobile SIM card. I'm surprised to see that Swiss (the airline) are giving their name for this product.
