We'd have to wait for Stu to comment on the instructions, for the practical side of the answer

I believe that despite the IoM number, it's based on TIM identities for Italy and for most of the world roaming, then a US ID as well from one of those regional networks with roaming on both the mains and others

subject to correction, something like that anyway

The dual sim has 3 profiles. Global roaming covers most of the world, USA roaming covers the USA and prime roaming covers Italy. The network used it Italy is Telecom Italia / Tim.

Easyroam,

When the SIM is in Italian mode is it direct dial or callback?

Italy also uses a callblack system

Call black? Freudian slip perhaps? I like that!

Why Italy?

Don't get me wrong but here in the United States we often judge people by their area codes...I've always wanted my 212 area code back when it was unceremoniously taken away from me 24 years ago in the first wave of area code splits (before they saw the sense of overlays!)...now I'm stuck with a second class 718 area code and my mobile phone in the US is a thiird class 917.....

So why would geosim have to go to a small town like Witchita Falls Texas and assign all their USA number in the 940 area code? I wonder what people are going to think about me when I give out this code.:)

I woud have to think that most folks in the US would not care about the area code assigned to an international sim, since they will be forwarding their local number (mobile, home, work, etc. ) to it. At least for me, I do not have a reason to give out the DID. So, any US number that works is fine.

My father used to say "Why wish for a loaf of bread when you can wish for the whole grocery store?"

If you are looking for snob appeal - why wish for a 212 number that can be anything from Harlem to the Bowery. Wish for a 213 number with the old BR2 exchange. That was (is) the exchange used in Beverly Hills for those that wanted a "local" LA rated exchange. (You pd. a lot extra for that privilege.) The regular BH exchange CR3 was (is?) outside the LA local calling area. It is also now in a diff. area code - 310 with "downscale" areas like Holmby Hills and Westwood.
There are now so many area codes, no one can possibly know where any of them are. In the U.S., a vast majority of people now pay nothing extra for long distance.
