Sometimes you want to keep your phone number private for a call and then switch it back again. You can do this by going through the phone settings, but it's a real pain because it's so deeply buried. This app enables you to quickly show or hide your Caller ID at the touch of a button.
This app works by using common network commands (where supported by the carrier). These MMI commands can be edited in the app so that you're able to set the right one for your carrier and country.
In the UK use *31# to hide and #31# to show (defaults).
In the US try *67 to hide and *82 to show.
If your code is not listed (or you can help other users by adding to this list), please email me.
This app works well on Android 2.2 with many phones/carriers. However, an update in Android 2.3 means that some MMI codes aren't dialled properly. I will try to fix this. If you want to get the fix as soon as it becomes available, install the app and tick 'allow automatic updating'.
Your feedback is appreciated (by email if you'd like a reply), so if you have any suggestions or requests, please let me know.
