Software Unlock

Both DoCoMo and Softbank have a few phones that can be software (sw) unlocked. This removes the need for a hypersim, but is only available on select models.

DoCoMo SW Unlock
The DoCoMo SW unlock is only available on NEC models. While the normal stuff are still useless, you will no longer need to worry about using a hypersim or CPRing, since a software unlocked phone doesn't have a hypersim.

Softbank SW Unlock
The Softbank SW unlock is only available on older Sharps, some Toshibas, and a few Samsungs. The older Sharps could have all features unlocked, along with a few of the early Samsungs. Nowadays however, they are completely locked down and the few phones that can be SW unlocked have the same restriction as DoCoMo phones with an SW unlock. haha
