The Benefits Of Unlocked Cell Phones

In sync with the development of mobile devices over the past thirty years have been the cellular networks that give them their name, even though there have been many issues regarding cell phone networks – from coverage and service to unlocked cell phones and contracts – not enough people completely understand exactly what a cell phone network is, or how it works. Excluding people that have unlocked cell phones, anyone using a mobile device most likely has a contract with a cell phone service provider, big companies like Verizon or AT&T being the two largest providers. What a cell phone user is basically paying for with their contract to these providers is the use of the cellular network they have established across the country – and abroad.

The network itself is just a network of fixed location transceivers called cell sites or base stations positioned at fixed geographical locations over a wide area. The range associated with a specific base station at which a cell phone can reliably connect differs depending upon many factors, such as the size and power of the station, as well as geographical features and other environmental factors. The range of each tower comprises what is referred to as a cell.

Therefore, a cellular network is really a series of strategically placed towers whose overlapping range of coverage is knit together, so that as long as a user is within range of at least one tower, they can connect to the network and maintain a signal, even when passing between various cells. Verizon and AT&T have both managed to erect a cellular network that covers about 95% of the population in the continental US.

Once connected to the network, a signal or call could be forwarded to any other device that’s been programmed (through a service provider contract) to the network. Moreover, cellphone signals received by cell sites can also be run from the cell tower through hard lines to reach standard telephones wired into a building or home.

When a cell phone is purchased together with a cellular service provider, the device is automatically programmed to be used with that company’s cellular network. For example, iPhone users are contracted to AT&T, and therefore all their calls are routed through AT&Ts network of base stations and cell sites. Unlocked cell phones are phones which have not been pre-programmed for virtually any particular network, allowing users to choose whichever cellular network works best for them.

This is often determined by a number of factors unique to each company’s contract and terms of services, as relates to the user’s needs and financial capabilities. However, the geographical solidarity of the cell network is arguably more important, based on where the user lives. In certain, more remote regions of the country, not all service providers have any installations physically situated nearby, and for that reason lack coverage.
