The Nokia Lumia 1020 Windows Phone 8 smartphone has encountered a price increase on Amazon.com for consumers wanting to sign a two-year contract with mobile carrier AT&T.

Amazon spiked the price of the Lumia 1020 up to $149.99 with a two-year contract. The price is valid for both an individual plan and family plan. In addition, the $149.99 price tag is eligible for new and current AT&T customers.

Current AT&T customers can pay the $149.99 price tag if they are upgrading their device or adding a new line of service to their account.

Amazon's "Without a Service Plan" price for the Lumia 1020 is $699.

According to Amazon, the buyer of the Lumia 1020 will be charged a "pro-rated Early Termination Fee" if the discounted Windows Phone 8 smartphone is canceled after the 14-day return period.

On AT&T's official website, the Lumia 1020 will cost the consumer an additional $50. The $199.99 price tag is available when the consumer signs a two-year contract with AT&T.

The official online Microsoft Store can also be purchased off-contract from AT&T for $610. At a physical Microsoft Store, the Lumia 1020 can be bought for $199 when signing a two-year contract with AT&T.
