Unlock your Sewon cellphone
Sewon - Creating mobile life
Is your cell phone locked to Sprint, NEXTEL, Cingular or T-mobile carrier network? Cell phone companies when you buy a phone from your provider will "lock" your phone, so it can only be used on their wireless network. Not very good when you want to switch providers, but maintain the same phone.
You may download software to generate the unlocking code. Software is available on some websites for free and some pay websites that also offer support if things go wrong.
Getting your GSM Sewon cell unlocked without spending a dime is possible too. Just find a free unlock calculator that generates a free unlock code for your model and enter the code it gives you into the phone.
But if you need to unlock loads of phones you probably will need some professional unlocking kit services.
