Good morning,
all these products of United-Mobile and their successors were technologically excellent, but at the end of the day they had to pay their bills....
United Mobile shifted the customer base from Mobilkom Liechtenstein to Jersey Telecom after some "discussions" on terms and conditions. The Liechtenstein Authority had reduced the interconnection fees, which made this business model possible.
But Jersey Telecom disconnected the service, after unpaid bills.
Free Time Telecom (supported by "white label mobile") for example offered 3 IMSI on one SIM-card, one number from Germany, one from Liechtenstein and one from the U.S. The vendor of the german mobile number (Telogic) went bankrupt, which was absolutely not under control of Achilles Rupf et.al. at all, but soon they had some internal "disputes" and from one day to another the services went offline, without any prior notice to the customers.
So pressing thumbs, that Naka will continue. But be prepared, if not.
Only recharge the needed amount, have a backup solution (another provider with another SIM-card) ready and give the secondary number to your important contacts.
The business case of roaming-sim-cards is complicated. They have to find enough customers, which bring them continuous revenue. The playing kids, the nerds and the "I want to play with it, if it doen't cost too much for me) don't bring the basis for prosperous life.
But this is a fundamental problem of most roaming cards.
