AT&T is making vigorous moves to attract new subscribers as it extends AT&T Next installments to 30 months for easy repayment options.

AT&T, the second largest wireless carrier in the U.S., is announcing a slew of attractive offers to bring new subscribers on its network. In its latest press brief Tuesday, AT&T added a new option to repay the device's cost through its Next installment plan, called the Next 24. AT&T subscribers will be now able to pay off the cost of their phones in 30 easy monthly installments. This extension allows more time with less monthly payments and also offers early upgrades.

According to AT&T, consumers get an option to trade in their device and upgrade to a new handset after 24 monthly installments under Next 24. The advantage is that customers get a lower monthly fee but at the cost of waiting two years before upgrading to any new eligible handset. Customers can also take advantage of AT&T Mobile Share Value plans with AT&T Next to get monthly discounts on access charge. It offers a discount of $25 per month on plans 10GB or higher or $15 per month for plans less than 10GB.

"Customer response to AT&T Next has been great. With a variety of payment options, they can choose the device and plan that fits their budget," David Christopher, AT&T's chief marketing officer, said in the press release. "AT&T Next gives customers flexible pricing options at an incredible value on a reliable network that keeps them connected."

For those who wish to upgrade early, AT&T Next 12 and Next 18 give better options. Under the Next 12 plan, customers can repay the device of the cost in 20 monthly installments and upgrade after 12 months. The Next 18 plan offers a 24-month repayment option with upgrade facility after 18 payments.

In a long-running competition to steal customers from other carriers, AT&T is throwing a treat to new joiners. If customers port their existing number to AT&T and choose any Next plan, the carrier will waive off $150 from three bills after 45 days.

The new AT&T Next 24 plan goes into effect starting Nov. 9.
