Unlocked iPhone
Apple was the first company to launch the iPhone in the market. The pre hype created about the iPhone had many people waiting eagerly to buy the iPhone as soon as it would be available in the market. The day arrived and the people rushed to get their sets as they were dazzled by the unlimited functions that they would get on the iPhone. The consumers were quite happy with all the facilities that could get on the iPhone and it was said that no other device could provide this type of unlimited facilities in a sleek and compact device.
But the initial happiness of the consumers was washed off and the shine of the apple iPhone decreased when they came face to face with the truth that the iPhone could function only with the help of the AT&T carrier service as Apple had a tie up with the carrier company and so the phone was locked and the consumers could not use the SIM card of other carrier services to operate their phones. If they wanted that the iPhone should have the email facility and the voice mail along with other facilities they had to sign a contract of two years with the AT&T Company.
Advent of Predam iPhone
The locked iPhone was a great set back for the company as most of the people were reluctant to sign a contract of two years with the carrier company and pay more than what they would pay by using the prepaid SIM card of other companies. Moreover the discount facility was not allowed by the AT&T Company this brought down the sale of the iPhone. Within a short period the predam or the unlocked iPhone was introduced in the market which had all the facilities of the iPhone excluding the compulsion of the carrier service.
Advantages of unlocked iPhone
The main advantage of the unlocked iPhone is the facility of using the SIM card which the user already possesses. This way he will be able to save the extra money that he has to spend on buying a new SIM card. If you are an avid traveler or a person who has to visit places overseas then the unlocked iPhone is more convenient as you can use the carrier service that is available at the place of your visit. The value of the unlocked iPhone increases and it can be easily sold to any person who wants to buy a second hand iPhone.
