This explaines the sometimes big differencen rates to some of these numbers.

United Mobile is a virtual operator on FL1, which is part of Telekom Austria, and a partner of Vodafone. CallKey depends on Manx Telecom, part of O2/Telefonica. 09 Mobile is rumoured to use Swisscom roaming agreements. Sunsim is an mvno on e-plus, owned by KPN. I don't know which network Travelsim lives on, but if it is EMT, this is owned by TeliaSonera

Whilst some practices have been less than competitive, I don't think the mechanisms are as you describe. The former monopolies are not in a cartel to drive out the free roaming cards, or shove tariffs upwards to reach them.

Perhaps T-mobile should take the view that if it can't beat them, join them. It's overdue that they and Orange make some moves on cheaper roaming.

And, off-topic, I don't understand why you have made your callback system so complicated. No hardware is needed at all, and lower tariffs exist on a couple of other Betamax brands.
