AT&T currently offers the 50% price discount on the HTC One smart phone with free shipping until June 30. The AT&T $100 price deal on the HTC One comes ahead of rival wireless carrier Verizon's July 2013 release on the Taiwanese smart phone.

However, the customers need to sign up a two-year agreement under the AT&T network. The customers who wish to acquire the in-store price discount must trade in as well their old phone which should be at least 3 years old or newer.

Even though AT&T is not considered as an affordable US wireless provider, the company can offer the most excellent network and LTE coverage in the subscriber's surrounding vicinity. At AT&T, consumers have the option of purchasing unlocked or international devices without a contract like the HTC One Developer Edition.

Other smart phones included in AT&T's limited 50% price discount are Samsung Galaxy S4, Samsung Galaxy S4 Active, LG Optimus G Pro, BlackBerry Z10 and Apple's iPhone 5 and iPhone 4S. With Verizon's fast approaching release on the HTC One, the smart phone price drop at AT&T is considered as the company's strategy in competing with the rival carrier as well as other retailers offering low-priced deals on devices.

AT&T joins Walmart and Best Buy in offering huge price discounts on smart phones. Retailer Walmart offers the iPhone 5 with a price of $129 and the iPhone 4S costs $39 on a 2-year agreement signed with a major carrier while Best Buy recently offered the iPhone 5 with a $50 discount as well as price discounts on some Android devices.

Based on one analyst's sales check report, HTC One is the third most well-liked smart phone in the US with or without a contract. The Taiwanese company's device is reportedly underneath the Apple iPhone 5 and Samsung Galaxy S4, the two technology giants, who continues to dominate the smart phone market competition.
