Sounds like an interesting academic exercise but one of little practical
value. You can buy unlocked 900/1800 phones for less than $30. That phone
might be of more value to someone who is interested in Verizon's GSM roaming
but who doesn't want to pay for the stupid device they now make you buy to
get it.

The stupid device is that dual mode phone. If you have Verizon and they are
sending a SIM, that's great. The point is that Verizon used to just send a
SIM. Last I heard they had changed their policy and required you to buy that
GSM/CDMA phone. All the customer needs is a SIM. He can buy a GSM phone
anywhere. If Verizon has changed their policy and now will send just the
SIM, that's a move for the better.

They'd probably want the ESN or something else you can't provide without
the phone in your hand.

You can get more with a kind word and a 2x4 than just a kind word.
If you give them the ESN, they will probably switch your service over to the
CDMA side of that phone and your old CDMA phone will stop working. Before
they came out with the dual mode (CDMA/GSM) phone, they would just send you
the SIM and tell you to turn off your CDMA phone when using GSM. Now they
have tried to idiot-proof the system by using just one device. Really,
Verizon's GSM roaming system is very good. Why they thought they had to do
it with just one device is beyond me. I wouldn't give them the ESN if you
can avoid it.
I once saw a break-down of VZW's roaming vs other carriers' and it all
depended on where you were going. Some places they were more than the
others', some places they were less. And, I didn't say their reps were
experts on GSM roaming. Most Verizon customers don't even know they have a
GSM roaming capability. And the dual-mode phone is just stupid; every bit as
stupid as the dual-mode Iridium/GSM phones were.
However, one thing I will add is that right now I wouldn't do much
international roaming with ANY of the US carriers' plans. They are all
rip-offs when compared with some of the prepaid international SIMs like UM,
O9 & TravelSIM. If you want to save money on international roaming, before
you go check out www.prepaidgsm.net.
It's a "feature" of Verizon's customer account system. I call it a
"misfeature"; it'd be a bug except that it's clearly intentional.
The way it works, if you have an ESN corresponding to a GSM/CDMA phone,
then the system automatically sets you to have Global Roaming service and
wants the serial number of the SIM card. If you then change the ESN to a
CDMA-only phone, then the system deletes Global Roaming and the SIM card
serial number.
That's why you can't change your ESN between an A840 and a V710 (say if
you're going into a known analog-only area) via the web page. You have to
get a customer service representative to do it. Fortunately, the need for
analog is diminishing all the time.
For similar reasons, customers can not switch between EVDO and non-EVDO
phones on the web page.
Telus Mobility in Canada also offers the A840, but you can buy just the
SIM card. Telus' account system does recognize customers who have both a
SIM card and a CDMA-only phone.
For what it's worth, Verizon's SIM cards are from Vodafone Netherlands,
and Telus' SIM cards are from Viking in Iceland. Neither company's SIM
card will register in North America. You can not put a Verizon SIM card
into a North American band GSM phone and expect to roam on Cingular or
T-Mobile.

For what it's worth, you can get new Verizon SIMs on eBay for about $25.

That's probably because the phone wasn't in their records as being sold at
a subsidy cost.
I got my A840 under a New Every Two deal. At the time Verizon told me
that they won't give me the GSM subsidy unlock code until after the two
years passes.
