In theory I understand this, but, does that mean these Global SIM companies have their own cell switch, both in the outgoing and incoming countries, and do the tricks that way? Or is it a full, say, Manx telecom SIM? Still doesn't explain (to me) why it is free to roam in countries Manx Telecom charges for.
