I just placed an order a T410 with Mobile Broadband Gobi 2000 GPS 3G.
I selected Open SIM card for Verizon
May I ask if this card support GSM (e.g. able to use GPRS, EDGE and 3G)? Is it unlock and could be use with any GSM carriers around the globe? (I am frequent traveller and have to switch the mobile number quite often)
Thanks for the information, I appreciated!
[Update]: I just called the Technical support to ask about this and the technician told me that, I cannot use other SIM card than Verizon one. This means I have to stick with Verizon Open SIM forever???? Is it true???

Strange thing is that the answer was from Lenovo Tech Support, not from Verizon.
And when I reconfirmed his statement, he still insisted that, this Gobi does not work with any other carriers but Verizon!!!
What kind of supports that lacks a basic information on their own product, do you think???
Any other users of this card can confirm this card unlcoked???

The Gobi 2000 supports EV-DO/CDMA as well as GSM/EDGE/UMTS. Given that feature set, it would be rather stupid to lock it to one provider. But then, you never know...
As a rule of thumb, tech support is clueless. I don't understand why you are surprised about that.

The GOBI hardware supports both CDMA/EV-DO and GSM/UTMS/HSPA carrier networks, but the issue is that corresponding laptop client software is needed to configure and authenticate the laptop to your account on the carrier's network. CDMA networks do not use SIM cards; they rely on an identifier number "burned into" the adapter (ESN/MEID). While it's technically possible to use another carrier network, the only CDMA network in the USA that will work with the ThinkPad's GOBI card is Verizon, not Sprint. I assume this is contractual between Lenovo and Verizon.
The phrase "Open SIM" means that the ThinkPad has an empty GSM SIM slot. If you ordered the laptop with the AT&T option, as I did, it would have come with an AT&T SIM card, which is easily removeable (under the battery). This SIM can be activated with a data plan. You could also obtain a SIM from AT&T, download their Windows client, and use the adapter with AT&T if you prefer. Note that when the AT&T SIM is installed, the Verizon option won't appear, and when the AT&T SIM is removed, the Verizon client option re-appears and the AT&T option disappears. There is nothing else in the laptop's "build" preventing you from using either carrier, regardless of how you ordered it.
I have no idea if other countries' wireless carriers support the GOBI adapter in the ThinkPad. Keep in mind that you cannot simply insert any carrier's SIM and expect it to work. It isn't a cell phone. You also need to have subscribed or prepaid to a DATA plan with the carrier, and that carrier has to have a GOBI Windows software client to install on the ThinkPad.

Thank you for your very useful piece of information.
In fact, I am using Swisscom SIM card with full 3G package as I often roam around European for Corp. Project Sales.
Regardless the name it's called, technical restriction (from within the hardware) is the only barrier to my daily usage. If the card does not support GSM natively (we know it does now, thanked to your info) and/or work with GSM, I hardly have no other option but to change the order, and that takes age to my works.
Anyway, thank again for the info.

I don't quite understand your reply, jamesnb, but here is some further clarification of my post:

You can also use Windows to manage WAN data cards connections, no other software required.

This is how I connect. I just installed the Lenovo Gobi 2000 drivers which installs the card as a network card. When the SIM is enabled on the network, you can connect.
You can 'pay as you go' with ATT - which if you only occasionally do a trip is a cheap way to get internet rather than paying $60/month as I used to:
