Why Is The Roaming Free?

Remember that most countries charge a premium for you to call a mobile number in that country. If the retail premium you pay to call a mobile number in X is cheaper than wholesale premium the carrier in Y charges X to roam in Y, then a SIM from X can roam in Y and the carrier can pocket a small profit from the difference in the prices. The key to understanding the situation is that wholesale roaming rates are much cheaper than the carriers have let on to anyone.
