No. The only Verizon Wireless phones that use SIM cards are Global Phones. SIM cards are only used for the GSM technology. Verizon Wireless runs off of the CDMA technology. So... if you switch the SIM card, the phone still won't work because it has nothing to do with the CDMA and that's what Verizon Wireless works off of. HOWEVER, you can activate a Verizon Wireless phone on an existing account by dialing *228 pressing SEND then choosing option 3.
How do sim cards become faulty?
There are three different ways a SIM card can become faulty:
1. The card is physically damaged. By being cracked, dropped in water etc.
2. The data on the card can be corrupted. This can be caused by shutting down the phone at the wrong time. Some phones will also destroy the card if you enter too many bad passwords.
3. The card itself is fine, but there is a problem with the phone company's record of the SIM card. This can happen when "porting" a phone number from one carrier to another. It could also be "blacklisted" due to unpaid bills.

Theoretically, is's a simply matter of swapping the SIM car. However - if the handset is 'tied' to Virgin mobile, you'' need to have the handset 'unlocked'. Most phones are already sold unlocked, due to changes in the rules for mobile companies - however - 'older handsets may have been purchased before the rules changed.
Swap the SIM card - if your phone shows the A. T. & T. logo, and/or you're able to make calls (or send texts) - then your phone is already unlocked.

Can I put a sim card from one carrier into an unlocked phone from a different carrier?
Theoretically yes but you should make sure the unlocked phone you are transferring your SIM card into also supports the same cellular providers operating frequency. Its like this, every GSM cellular service provider operates in one or two of these possible frequencies 850/900/1800/1900 MHz. This will depends on the carrier and the country in which service provider operates, its usually 850/1900 in North America and 900/1800 in Europe and Asia. Most of the phones sold in the USA/Canada work in the North American frequency and not in other, so make sure your new unlocked phone works in the particular frequency for your provider.
Usually you open up the back of your phone and your sim card is being held in a holder, sometimes you may have to remove the battery if it's in the way. You take that sim card out and put in your new one. Sometimes phones take a minute or two to load with the new sim card. If you do that, it should load the sim cards information and regular phone number, unless it is a sim card from a different service provider, which in that case it may not work and show errors.
AnswerIf your phone has one, turn off the power, remove the battery and typically the sim card is behind the battery. Often a clip or slide holds the sim card in place so you may need to examine it to figure out how to remove the sim card. YOU TAKE IT OUT AND PUT A DIFFERENT ONE IN!
