depending on whare you take it in a certified place it can be up to 45 dollars if u do it yourself oreder your unlock code only it can be up to 25 to 30 dollars

Have you tried removing the SIM and even try airplane mode

Okay i see what you need to do is connect your phone to the web and download it

bu not sucess

your security code is 9999

If your Softbank 740SC is UNLOCKED, you should have no problem with this 3G/GSM phone.
If the phone was bought as a pre-paid/subsidised unit, then it would be locked and, if you are the original owner with proof of purchase, you can try requesting the Network Unlock Code from the original service and phone provider.

to unlock the phone get the code from the service provider or from online site....
