Hi if the samsung u700 mobile is locked with optus network provider then you can't use it with 3 network sim until you unlock it .You can easily unlock your phone using sites like Unlocking4U.com they are rendering unlock code for all mobile models at reliable cost .You first check that whether the code is available for your country and network provider .If yes then pay for it and unlock your phone then freely use it with any GSM sim .
