Yes your "a, b, c" is exactly true. But the calling mechanism for a mobile to mobile call is actually quite different, let me explain:
Nimbuzz allows you to call from your mobile phone at local rate to other Nimbuzz users on their mobile. You don't pay anything to Nimbuzz, you pay the local rate to your mobile provider. The receiving mobile party also pays local rate to their operator.
Result: No international roaming anymore.
And as the actual call is made via GSM, the quality is perfect.
So we don't use the data network for the mobile voice leg, the data network is only used for call setup. Therefore no Wifi, UMTS or EDGE connection is required. Plain GPRS is sufficient. And it works without exception of any operator.
But Nimbuzz also allows you to make calls from mobile to PC users, whether they are Nimbuzz, MSN or GTalk users. Then the calling procedure is similar to the above with the exception of the receiving leg. This of course is VoIP and there are no cost at all for the receiver.
I expect that this explanation really does answer your question. We will take action to improve the information on this subject on our website.
Other relevant information on this subject:
(1) If you have a domestic (and not an international) mobile to mobile call, you are automatically directly connected to the other party, not using the Nimbuzz accesspount at all. Thereby avoiding the need for 2 local calls on either side (2) Using Nimbuzz mobile, you always pay local rate(supported in 35 countries, check website) provided that you actually make the call when you are in your home country (e.g. US). Otherwise your operator will charge you for calling to a US number (the Nimbuzz US accessnumber). But this is nothing new a presume...
