I put my trust now in TravelSim.

If anyone can explain the business model behind these free roaming SIMs i'll be happy to learn something.

It is readily apparent. The roaming is NOT free. The bill for the call shows up on your home or office or customer's bill when they call you. These costs are MUCH higher than making a call to a cell phone with a regular lst world SIM. The costs imposed to call a LIctenstein SIM, were so high that many LD carriers in the U.S. refused to route calls to a Lichtenstein (ergo United Mobile SIM because they had to deal w. outraged customers when they got their bill.
The Estonian SIMS, while imposing high costs upon callers, aren't quite as outrageous as Lichtenstein was. Estonia only double most other countries instead of triple or quadruple.

Bottom line - your friends and clients are paying big bucks so you can get "free" calls.
