In the last decade, mobile phones have stopped being juts a device for voice calls but have become a gadget for data communications. First, there was SMS or Short Message Service, a service that allowed people to send alphanumeric messages to mobile phones using the GSM network. Now the mobile phones have been packed with so many features including full keyboards, multi-media support capacity, internet connectivity and other mobile applications.

Palm Inc. was among the first to introduce Smart phones with emailing and internet connectivity and full keyboards that made it easy to use the mobile phone as an extension of one's office. Today, the Treo Smart Phones from Palm Inc. are among the top choices of business executives and other professionals because of the mobile applications that allow people to use their phones for a variety of purposes. All high technology features of the Treo Smart phones would be for naught if it weren't for its ease of use. The latest Treo Smart Phones with Windows OS are even more easy to use than the first Smart phones introduced years ago. The Windows OS also allow the Treo Smart phones to handle Windows documents better allowing you to work seamlessly between your PC and your mobile phone. Both the Windows OS and the Palm OS also make the Treo phones among the fastest mobiles in the market, allowing for a great computing experience and a seamless internet connection. One of the most popular PDA phones from Treo is the Treo 650.

If you bought a Treo 650 Smartphone locked to a specific GSM provider and you prefer to use with another service provider, then there is a way to unlock your mobile phone. You can even do it remotely without the need to ship your mobile phone to the unlocking company. There are remote unlock codes that you can get from websites and you can just use the code to unlock the phone at home.

The first step you should do is to sync all your data with your PC. The phone comes with a hot sync cable for this purpose. This is important because you might delete some information from your phone without meaning to. This will save you the hassles of losing any important data.

After you have complete backed-up your data, you can already start unlocking your phone. Insert a SIM from a different service provider in your mobile phone. When you turn the Treo 650 on, a message saying ?SIM NOT ALLOWED? will be displayed on the phone's screen. Just click OK and use the stylus to enter the code that was provided to you by the ?unlocking company?. To enter the code press * # * # (CODE provided by the unlocking company) #. After you have entered the code, the message ?SIM LOCK REMOVED? should appear on your screen. You are now free to use any SIM from other service providers and even use foreign pre-paid cards on your phone when you travel to other countries.

There are also unlocking processes that include the use of software. Usually, you will be provided by a step-by-step guide on how to unlock your phone when you acquire an unlocking code. The whole process should take less than 5 minutes.
