Yes, surprised there have been so few comments. Thanks. Further responses & clarifications.

"How the billing system recognizes the card without the PIN?"

Two methods:

1. You can dial in and choose to have the # remembered with a menu option
2. They have online forms where you enter #s you want to use

"Do you mean DID based callback?"

I believe this is it, but you must register your #, actually up to 3 numbers. Like method 2 above.

"What exactly? You can use CBW with a mobile phone..."

What I meant was that MCI, Enjoyprepaid, Onesuite, for instance, will not allow NON-US numbers to be registered for pinless dialing.

"Pinless dialing?"

Yes, pinless dialing.

As to my wife, she forgot. Not the first time, either, but I can forgive and understand that. I forget things, too..... my keys, my glasses, my credit card, etc.

"Do you want to program in the Riiing SIM, or the phone's memory a "single dial" entry like +1234YourCBWDID#something#+1567YourDestinationNumb er?
I'm afraid it's simply impossible with callback"

TRUE. I can program the single dial (CBW entry). I can't USE the entries in my phone book to dial the final destination # AFTER the callback. Think we need tone generators for that WITHOUT dialing.
