Priced in GBP, expensive SMS, postpaid version for business users only.
Useful info: USSD codes for uncompatible phones are provided :)

It appears that incoming is FREE in each of the countries (only about 70) you can use. I entered several and they all came up w. "free". Outgoing seems reasonable enuf when compared w. others. They claim to have a real VM system. And, unlike other companies that have appeared here over the last several months but never have seemed to get their act together - they seem for real.

Incoming calls aren't always free: you can try entering Malta or Malaysia to take a look...

And of course USA and Canada 0.59 GBP (I guess Snidely, it's because you're an American and you don't need such a roaming solution at home :) )
And Cuba and India :cold: :P - look by yourself!
