Cell phone companies in the United States and around the world are only two types of networks: Code Division Multiple Access (CDMA) and Global System for Mobile Communications (GSM). Though each technology transmits voice and data, they do so in different ways, making a compatible phone, if you do not the right plan. Therefore, you can not take a CDMA phone and use it on GSM or vice versa. GSM phones can be taken for use in other countries (as a frequency compatible - please come back later in dual band / Tri-Band / Quad-phones band).
Verizon, Sprint, Cricket, Alltel, U.S. Cellular, Cellular South all work with CDMA networks. Will find a phone that is called "CDMA" in the description. If the description says works for Verizon phone works only on the Verizon network, and the same for Sprint, Alltel, U.S. Cellular, Cellular South, Metro PCS, Cricket, etc.
AT & T, T-Mobile, Fido, Vodafone, Orange, Rogers Wireless and many other GSM Global Supplier operate worldwide in a GSM network. If the phone is specifically stated that "guaranteed to work with AT & T, for example, the phone is currently "locked" and only works with AT & T and even T-Mobile and so on. These phones generally can not be easily released for use with any GSM carrier uses a SIM card for an amount low (ranging from $ 8 - $ 20) and opportunity to unlock the phone depending on the model of phone you buy.

If states phone "Unlocked" in the title or description that you can take your SIM card into your existing GSM phone and put it in another phone GSM unlocked. If the description states: unlocked, you can use on any GSM network worldwide. Only phones GSM can be unlocked So please get the word mobile in the description. In addition, you must ensure that frequencies supported by your phone is compatible with your mobile phone provider today. Here are some of the most popular companies operating frequencies. You may just want to make a quick search on Google to see what the frequency of a specific phone / carrier operates to ensure that you most of the reception with the phone.
Then my Verizon / Alltel / Sprint / U.S. Cellular / Cell Phone South is unlocked?
No, sorry ... All companies above operate on CDMA networks and therefore can not be unlocked. Note that phones GSM can be unlocked. Some CDMA phones are compatible with dual SIM card to use internationally, but for the most part CDMA phones can be unlocked.
Power AT & T / Cingular / T-Mobile / Rogers phone is unlocked?
Yes! Although for the most part. Most GSM phones can be unlocked. All companies mentioned above operate in GSM ntworks. All these suppliers wireless service, providing an activation of the SIM card. If you have an AT & T phone and want to use your current service plan with another phone AT & T, all you have to do is take the SIM card and place of the AT & T and the phone can use the phone Freel. If your phone uses a GSM SIM card can be unlocked. Locking a phone is one way companies to prevent their customers to switch to phones with other carriers. Once a carrier has determined that I will not let you go easily. Carriers also have deals with manufacturers of large cell phone to make calls some of them exclusive and pay $ $ $ To try to prevent people from easily being able to use their phones in other networks.
