Why is my mobile phone locked to DoCoMo Japan?
If your phone is locked to Docomo in Japan, it means your phone is under contract..But still you can use another service providers sim by unlocking your phone…
You can unlock your phone by contacting the service provider or using online services…Online services are recommended as you can unlock your phone from anywhere in the world….I can suggest you Mobileunlocker.com where you need to mention your phone model…They provide you with unlock codes and free instructions to unlock your phone…
When you buy a cell phone it will be offered at a discounted price by DoCoMo Japan. They “lock” your cell phone to DoCoMo Japan in order to tie you in to their service and recouperate their costs. This means that you cannot use the SIM card of another network, and if you try to do so the phone will display “Phone Restricted”, “Contact Service Provider”, “Enter Unlock Code” or a similar message. Unlocking the phone removes this lock, allowing you to use your on any GSM wireless network anywhere in the world.
