All of us rely on smartphones these days and they have become an integral part of our life. You can
not imagine leading a normal without smartphones as all of us use our smartphones for multiple
purposes.
Smartphones are basically high-end mobile devices that are built on a mobile computing platform.
These smartphones have advanced features and functions and they offer abundant connectivity options
as compared to other feature phones. When smartphones were introduced, they were basically devices
that combined functions of a personal digital assistant (PDA) along with a mobile phone.
But smartphones have evolved and become highly sophisticated devices and they boast of features like
high speed internet browsing, personal music player, advanced digital and video camera along with
GPS navigation ability. Most of the smartphones these days have a touch screen interface, high
resolution screens and web browsers that offer high-speed data access though Wi-Fi and mobile
broadband.
Most of the smartphones used around the world these days are based on mobile operating systems (OS)
like Google's Android, Apple's iOS, Microsoft Windows Phone, Nokia Symbian and RIM BlackBerry
OS. The biggest difference in smartphones used these days over old smartphones is that they offer huge
amount of storage and they can easily get multiple OS software upgrades without facing any problem.
Smartphones use GSM technology and many GSM network operators lock their GSM phones so that
these GSM smartphones can be used only in a particular network operator or country. But you can get
unlock GSM phones easily and most of the GSM phones can be used on different GSM networks after
they are unlocked.
The easiest way to unlock GSM phones is to enter a code that has been provided by a network operator.
But other way to unlock GSM phones include installing a software or attaching GSM phones to a
computer or though hardware devices. Another way to unlock GSM phones is by getting over the air
updates by a network operator.
Some phone manufacturers allow GSM phones to be unlocked by a code that helps to remove all locks
from GSM phones. This code is usually referred to as the master code, network code key, or multi lock
code. A locked GSM phone would display a message if a restricted SIM is inserted and need an unlock
code. After entering a valid unblocking code, GSM phones can be unlocked and used with a different
network operator. An unlocking code is first verified by GSM phone and generated by a network
operator. After GSM phones have been unlocked they can be used effortlessly with various network
operators.
