Why Unlocked Cell Phones Are Better

In sync with the progression of cellular phones within the last thirty years have been the cellular networks that give them their name, despite the fact that there have been many concerns regarding cell phone networks – from coverage and service to unlocked cell phones and contracts – few individuals 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 currently being the two largest providers. What a cell phone user is actually 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 often known as cell sites or base stations situated at fixed geographical locations over a wide area. The range of an specific base station where a cell phone can reliably connect differs depending on several factors, including the size and power of the station, along with geographical features and other environmental factors. The range of each tower comprises what is known as a cell.

Therefore, a cellular network is really a series of strategically positioned 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 get connected to the network and maintain a signal, even when moving between various cells. Verizon and AT&T have both managed to erect a cellular network that covers about 95% of the population within the continental US.

Once connected to the network, a signal or call could be forwarded to any other device that has been programmed (through a service provider contract) to the network. Moreover, cell phone 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.

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

This can be based on many factors unique to each company’s contract and terms of services, as pertains to the user’s needs and financial capabilities. However, the geographical solidarity of a cell network is arguably more vital, depending on where the user lives. In certain, more remote regions of the country, not all companies have any installations physically situated nearby, and therefore lack coverage.
