Unlocked cell phones are those that are not tied down to a carrier’s network. It will typically work with a variety of service providers.
Most smart phones and cell phones are tied to a single service provider like Verizon wireless, Sprint, AT&T or T-Mobile. Even if you buy the phone from anywhere, you may still have to stick with a particular carrier. For example, if you buy iPhone from any store, you will still have to operate with AT&T’service. Such phones are called as locked phones.
For many reasons, purchasing a locked phone makes sense. The service provider may provide attractive discounts and deals to the phone locked into their service.
But many others may not like being tied down to a single network as in the case of locked phones. For people traveling abroad frequently it does not make sense to carry the same network while traveling as it will cost the earth to make a roaming call. In such a case they would prefer to access local networks while staying abroad and in this case, unlocked cell phones make better sense.
Some people may also not like to sign lengthy contracts with service providers as they are on the move all the time. Unlocked cell phones are better suited to their needs.
So you might consider trying to unlock your cell phone. Some smart phones and cell phones can be unlocked but they require external help. Once you have bought a locked cell phone it is in the interest of the service provider to keep it locked so they make unlocking a difficult process.
Some phones can be unlocked by altering their software but others may require tweaking their hardware. You can ask your service provider to unlock your phone but it is less likely that they will oblige especially if you are still under contract. Now the alternative is to ask a third party to unlock it for you typically for a small fee. But if your phone gets damaged they are under no obligation to replace it.
Take note that it does not make sense to unlock your phone until the present contract period with an existing service provider is completed or you will end up paying for whatever service you do not use.
Unlocked Cell Phones are useful to those who like to change service providers often and those who travel most of the time.
