The Nokia Lumia 521 has finally made its way to T-Mobile online.

T-Mobile is offering the Lumia 521 for one full payment of $149.99.

Customers, however, do have the option of putting a down payment of $29.99 and make $5 monthly payments for the next 24 months.

After choosing the method of payment, customers have to choose among three data plans, each with unlimited talk and text. The first data plan includes 500MB of high-speed data, while the second plan offers 2GB on top of the 500MB. The final data plan option is the Unlimited Nationwide 4G, a recommended choice by T-Mobile. Prices for the data plans vary, as the 500MB starts at $50, 2GB for $60 and $70 for the Unlimited Nationwide 4G, per month, respectively.

T-Mobile is also waiving the $35 activation free with the purchase of the Simple Choice Plan: Unlimited Talk and Text.

Additional services with each data plan include call forwarding, call hold, call waiting, caller ID, conference calling, and customer care.

The new Windows Phone 8 smartphone, exclusive to T-Mobile, has been available since May 11 at Microsoft Retail Stores for $149, Walmart, and even a showcase for HSN late last month, although for $0.95 more than Microsoft's offer.

The Lumia 521, which is 4G enabled, has a 4-inch touchscreen and 5-megapixel camera with 720p HD video recording. When it comes to memory, the smartphone has 8GB of internal storage with 512MB of RAM. A microSD card slot is available for up to 64GB of additional storage. The battery capacity for the Windows Phone 8 smartphone is 1,430mAh.
