Unlocked Cell Phone

The hunt for no contract cell phones for sale usually means that buyers are actually looking to purchase unlocked used cell phones. Typically, when a mobile phone is purchased the owner signs up with a new wireless carriers plan and receives a reduced rate or a free phone with the contract. Even if the phone becomes deactivated whenever it is placed back into service, or reactivated, it remains on that specific carriers network. Obviously, it works to the advantage of the wireless carriers to have their customers purchase locked cell phones as this is their way of keeping the customers 'locked' into their wireless service. Purchasing a GSM unlocked used cell phone means you just have to change the GSM SIM card in order to change the carrier service. Then the mobile phone would instantly access the new network service. CDMA mobile users can get unlocked phones, but, don't usually do it because they specifically wanted the network they chose. Places that have no contract cell phones for sale will typically offer both CDMA and GSM from providers such as Verizon Cell Phones, Boost Mobile, Alltel, Sprint, Nextel, AT&T / Cingular, T-Mobile, Ntelos, Cricket and Others.
The greatest benefit to the unlocked mobile phone is NO CONTRACT and you actually own the phone rather than 'leasing' it. Among the brands of unlocked used cell phones available are Audiovox, Apple, Dash, Bluetooth, HTC/MDA, I-mate, LG InfoComm, iPhone, Nokia, Motorola, RIM BlackBerry, Palm/Treo, Pantech, Panasonic, SideKick, Samsung and Siemens.
