Any smartphone that uses SIM card has the potential to be
unlocked. A SIM card stands for subscriber identity module. It contains all the
encrypted and personal information about the smartphone user. All smartphones,
which have SIM cards, will operate on the GSM phone network. This means these
smartphones could be unlocked and used on another GSM phone network.
It is possible for smartphone users to unlock some models;
many people prefer to purchase unlocked phones. The main reason behind this is
most of the users don’t know how to unlock phones and there are detailed
instructions for unlocking smartphone on the Internet in which some models
require complex procedures to unlock. And if the procedure is not followed properly
then the phone will be hard-locked or dead and not used further.
Many service providers require consumers to sign a service
contract, which is usually for two years and if the user breaches the contract
then it will be quite costly for the consumer. Another option is, purchase the
unlocked version and insert the SIM of pervious smartphone into it. This will
also prove beneficial for those users who frequently travel abroad because it
can be used on many other worldwide service provider networks. International
roaming is quite expensive and purchasing a SIM card of local service provider
is better option.
Smartphone users who break phones frequently are also advised
to purchase unlocked smartphone and also for those users who purchase new
models more frequently have to pay a service fee to the service provider for
switching the information to a new phone. Users who purchase unlocked phones can only switch the SIM card between phones without
paying any fee to the service provider.
Unlocked smartphones are better than locked smartphones and
offers a variety of advantages, including the freedom to select the network
service provider of our choice and ability to use in overseas without incurring
costly roaming charges. The consumer will have to pay more for unlocked
smartphone rather than locked smartphone but the freedom of choosing the
network provider of your choice justifies the money spent.
