US mobile phone operator Verizon finally started selling the iPhone, providing Apple fans with an option with respect to carrier.

Until the availability of the Verizon iPhone, network provider AT&T had been enjoying exclusive rights to sell the iPhone since it was launched in 2007.

Apple decided to launch the iPhone via Verizon following frequent complaints regarding AT&T’s allegedly poor network service.

With an intention to attract more and more customers, Verizon has announced numerous incentives, including an unlimited data plan with a price tag of $30 per month. AT&T is offering just 2GB of data per month for $25.

When asked about AT&T’s ability to allow customers to make calls and surf the web at the same time, Verizon said, “The ability to simultaneously use voice and data might matter to some people, but the majority of customers would prefer to be able to make a phone call.”

Verizon is expected to sell as many as two million quarters this quarter. But, AT&T claimed that it was unconcerned about the increasing competition.
