I've got an N900 on the T-Mobile data-only plan (Total Internet, $40/month). I don't have a voice plan (I'm using SIP instead).

Is there anyway to disable the contact/phone apps menu prompts for calling via a phone plan? (I'd also like to disable SMS as well as I use Google Voice for SMS via e-mail.)

It's especially frustrating as the phone will default to the voice plan if I'm trying to return a DID-inbound SIP call.

Basically, I'd like the contacts/phone app to provide e-mail/SIP/etc, but not to include the voice-plan relevant options.

Any ideas?
