Despite some uncertainty surrounding its release, T-Mobile is now the first U.S. carrier to offer the Google Nexus 9 tablet for sale.

The nation's fourth-largest wireless service provider began selling the tablet Friday, December 12 through its Underground store. Interested buyers can now pick up a Nexus 9 for $600 or a payment plan that includes $0 down and monthly payments of $25 over two years.

"T-Mobile is the first U.S. carrier to offer the LTE Nexus 9 tablet -- and is the ONLY place Nexus 9 customers can get the best tablet plan in wireless this holiday season," reads a company press release. "Just $10 a month enables you to add a tablet and match the data on your Simple Choice voice plan-up to 5 GB a month-for use specifically on your tablet. And all T-Mobile tablets can get you Free Data for Life, giving you 200 MB of free data a month for the life of the device as long as you use it with T-Mobile."

The HTC-manufactured Nexus 9 features an 8.9-inch IPS LCD display with a 2048 x 1536 resolution, 2GB RAM and an NVIDIA Tegra K1 Dual Denver processor. The Nexus 9's rear-facing camera can take stills at 8 megapixels and record 1080p video, while the front-facing shooter takes pictures at 1.6 megapixels and video at 720p.

The Nexus 9 release comes just after T-Mobile announced a new Simple Choice family plan that allows consumers to purchase unlimited 4G LTE data for two lines for $100 per month. Additional lines can be added for an extra $40.

"People are saying loud and clear that they hate the confusion and complexity of the carriers' shared data plans, and they should," said T-Mobile president and CEO John Legere. "These plans are purpose-built to do one thing -- take money from your pocket and put it into theirs. They threaten you with punishing overage penalties unless you police your own family's data usage or up your data bucket and spend more every month.

The Nexus 9's release also precedes a T-Mobile "Uncarrier 8.0" event Tuesday, Dec. 16. Although details on what the carrier will unleash are still scant, it's worth betting that T-Mobile will once again try and shake up the wireless industry.

The maverick carrier has already done away with industry-standard contracts, upgrade restraints, and a number of other industry standards in an attempt to lure consumers away from AT&T, Verizon, and Sprint.
