Does anybody reading this know how to get someone from Apple to get the answer for us. I am sure there are many users with the exact same problem we have. Is it now only possible by way of a carrier bundle over the air or embedded in the SIM?


My carrier has no clue and says the old code should work on 4S, but obviuosly it doesn't.


Apple where are you?

Unfortunately it appears you are correct. Something has changed with iOS5 that prevents the maintenance codes from overriding settings on factory unlocked iPhones that use unsupported carrier networks, because the code does work on the iPhone 4s that is bound to an official carrier.


It used to be possible to upload the ipcc file to the iPhone directly, but this is no longer allowed, so it seems until your carrier has a carrier settings file that can be pushed over air we're going to be out of luck.


I can think of one other way to get the ipcc file onto the iPhone, but this method surely be frowned upon by Apple, and currently isn't an available option for most anyway.

Yep, same problem for me too. I'm on BASE too and my old iPhone 4 worked fine but not my iPhone 4S.

I called BASE and they are aware of the problem. They suggested I try *5005*86*+32486191933# but this didn't work.

I have version 5.0.1 (9A405). Which release will we have to wait for to get this fixed?


On a side note, why am I not allowed to have Visual Voicemail?
