HTC Corporation is the Taiwanese manufacturer responsible for a number of extremely popular smartphones and tablets. It was founded in 1997 and remains headquartered in New Taipei City, Taiwan. From its humble beginnings to being name “Device Manufacturer of the year, 2011” by the GSM association, HTC has grown to be one of the leading contenders in the smartphone market. HTC started out designing and making mobile phones and PDAs based on the Windows Mobile Operating System, then selling them to companies who were willing to pay for customised products. However in 2009 they began releasing their own models using the Android OS. Peter Chou and Cher Wang founded HTC back in 1997 as a manufacturer of notebook computers. It was a year later when they began designing some of the world’s first wireless, and often touchscreen, hand held devices. HTC is now ranked in the top 100 of the Interbrand “Best Global Brand Report, 2011”. They are widely credited with creating the first ever windows and Android mobile phones. In 2009 they launched the brand tagline “quietly brilliant” and also unveiled its first ever global advertising campaign. In 2010 HTC sold 24.6 million handsets and its revenue for last year topped 6.75 billion dollars. As a company, HTC have done amazingly well in recent times. They are one of the most popular phone brands on the market today, with many of their leading phones also being amongst the most popular that we unlock. One of their best masterstrokes has to be offering Beats Audio technology built into their phones, which has really caught the imagination of a new audience. HTC phones are very reliable at telling us when they are locked. If you are unsure, simply insert a non-accepted SIM card (one that isn't from the original network) and if the phone prompts you with a Network Locked message, you can be sure the phone is locked. Unlike other handsets that can have various different types of locks placed on them, HTC will only ever have the one. This means that HTC phones only require 1 unlock code, which can be used to remove the lock stopping you from using the SIM card you want to use.
