What Are Unlocked Cell Phones?
In order to understand what the unlocked cell phones are, let’s take a quick look on the technology behind making that phone call or sending an SMS. You can look at the cell phones as some sort of mini radio transmitters; in fact, this is exactly what they are – when turned on, the mobile phone will transmit radio signals that are “caught” by the nearest base station and when you try to reach another cell phone user, your cell phone signal will be transferred via relays to the recipient’s cell phone.
Of course, most of us don’t really care much about the technical details – we want cell phones with great features that are reasonably priced; well, this is what most locked cell phones are: in order to keep the prices low, many of the mobile carriers offer brand new and popular cell phones at very reasonable price and quite often for free. What is the catch then? In most cases you will have to sign a contract, with two years being the norm, and the cell phone that you get can be used only with the provider that you have signed with; the unlocked cell phones, on the other hand, can be used with any provider, but they sell at full retail price and that makes them more expensive.
In many cases the locked cell phones are good for both sides – the mobile carriers can attract hundreds of thousands of new customers by offering new and popular phones on promotion, while the customers themselves can get the latest phone for next to nothing, instead of paying hundreds of dollars. Of course, not everybody is happy: once you sign a two year contract, you are pretty much tied up because of the early termination clauses. Owning a cell phone that works only with a specific provider is quite inconvenient as well: the unlocked cell phones will work pretty much in any part of the World, as long as there is an open network available; if you have a locked phone and you do not wish to renew your contract after its expiration, then you cannot use it at all unless you manage to unlock it.
