There is no better deal than getting something for free! So if you've always wanted the next best smartphone but didn't have the cash to shell out for the most high-tech phone there is, you're in luck.

You can actually get some of the latest models from some of the biggest names in the mobile industry right from Amazon and AT&T.

Of course, the incredibly sweet price tag of $0 depends on the type of contract you sign up for with AT&T, and most of the time, the "free" phone actually only refers to what you pay upfront, and you will eventually pay for the unit in easy-to-manage installments for the duration of your contract. The deals are still pretty tempting, and it may be the perfect opportunity to get your hands on the touchscreen smartphone you've always wanted.

Here are the best deals from Amazon.com where you can get a free phone (plus applicable taxes on full price of the unit and other fees) by signing up for a 2-year contract or AT&T Next (12, 18, and 24):

Samsung Galaxy Note 4 (32GB)

The Samsung Galaxy Note 4 is great for those who like to carry their office around, literally, in their pocket. The screen is comfortably large enough to read, yet not as big as a bulky tablet. The S-Pen also allows you to write notes and scribble quick doodles while on the go. It comes in Charcoal Black or Frosted White.

LG G3 (32GB)

The sleek, metallic look of LG's G3 line makes it elegant and comfortable to hold in your hand. The latest model also boasts an HD (2560 x 1440) screen, superb camera, and a Guest Mode that allows you to let others use your phone to make calls or send SMS, without compromising your more confidential information. It is available in Metallic Black and Silk White.

Nokia Lumia 1520 (16GB)

Nokia has always been known for their no-nonsense, durable phones. This smartphone is no exception. Running on Windows Phone 8, the Nokia Lumia 1520 is one of the few smartphones to natively offer Windows Office to view and edit documents right in the palm of your hand, making it a perfect mobile workstation. It is available in Black.

For all the deals and contracts listed above, the prices do not include local sales tax and other carrier-specific fees. The offer is also good for a Samsung Galaxy S5 (16GB), Samsung Galaxy S4 Active (16GB), BlackBerry Q10, HTC One M8, among others.  For more information, check out the official listing of Amazon and AT&T for everything you need to know about these phones and others in their $0 promotion.
