No. Verizon is CDMA. They don't use SIM cards. The phone you have has dual-radios so it can run on GSM or CDMA.

The Blackberry Bold is CDMA compatible, not the sim card. That phone will work with GSM or CDMA because it has a dual radio chip. The sim card is for GSM. You can't use a sim card to connect to Verizon towers.

If you are planning on taking the sim out of the Bold and putting it in an AT&T (GSM) iPhone to access Verizon, it will not work. It will not work even if you get a factory unlocked GSM iPhone. They don't have a CDMA chip and they only work with GSM carriers. If this worked, people would have been unlocking AT&T iPhones to use Verizon long ago. There is no such thing as a Verizon sim card.

You need to use a Verizon (CDMA) iPhone to connect to Verizon.

Ehhhh, Verizon does use SIM cards for their network. Just on the LTE Android phones though. :)

The verizon "SIM" is for world mode, meaning you can roam in most countries (the cost will kill you).
If you are not a world traveler, then the sim does absolutely nothing for you. You could take it out and not see a single difference in service here in the US.

Nope, the Verizon LTE SIM card is for use in the good ole USA and is specific to the new 4G devices they offer. Just had one replaced on the wife's Thunderbolt to solve a reception problem. They work just like the GSM SIMs and can be placed in any Verizon 4G phone and immediately work.

Thanks, that's good information. I didn't know the Thunderbolt had that option. However, this won't make any difference to the OP. He wants to get an AT&T iPhone 4 and use it with Verizon. The iPhone 4 is not LTE-compatible, so it's still currently impossible to use Verizon on an AT&T iPhone.

The OP's question was about a SIM in a blackberry bold- which is not a LTE device - a technology that currently only has a couple of phones that work on it.
Prior to LTE, Verizon had/has phones- like the blackberry bold- that have regular SIM cards in them that were for World Mode, enabling international roaming. That is what the OP has in his phone. It is NOT for LTE, and while it can roam in the US, since it is made to roam on any GSM network, it actually has no bearing on his current Verizon service in the US.
Your assertion that the Verizon LTE SIM works in the US is correct, but it's irrelevant to his question, since his SIM is GSM, and not LTE.

Fully aware of that, but another poster (Europa) stated that they don't use SIM cards, which is what that post was in reference to. To be correct, the statement should be that none of the 3G phones use SIM cards for US transmission. That is why I specifically stated LTE and the phone type that supports it. :)
they currently have 4 phones out (I think) that are LTE. Any CDMA phone with a SIM is a world phone and the GSM freq's are for overseas use. I don't think they are compatible with US freq's, at least mine weren't.

Yep, best bet (if he already owns the AT&T iPhone) is to sell it and take the proceeds and put towards a CDMA Verizon iPhone (preferably off contract since the new one is just around the corner).

I think everyone has this correct. The SIM cards in VZW's 3G phones are for global use only. Outside the US, these SIM cards will allow you to roam on GSM networks in other countries where VZW has roaming agreements. As stated, that roaming use will cost you a pretty penny.

All VZW 4G devices require a SIM card for use on the VZW network right here in the US. Even the CDMA authentication on these dual mode devices requires the LTE SIM (meaning a 4G dual mode device cannot work on the 3G CDMA network with that SIM card). The 4 4G Smartphones along with all the 4G data devices work this way.

With SIM cards being new to the VZW subscribers, the nice thing about them, is you're able to move that SIM card from one device to another. (something Europeans have been accustomed to for awhile with unlicked phones) As an example, I have the vZW 4G Mifi device and also have a 4G LTE data dongle. I only have one account (which means one SIM) and I can move that SIM between these two devices, depending on what I want to use.
