Unable to set conditional call forwarding using MMI codes on iPhone with iOS 26

I use a 3rd party answering service when I am unavailable. I cannot set my conditional call forwarding using the MMI codes (61,62,67)


Please let me know if there is a solution to this as I use the service everyday.


Thanks

David

Not all countries and not all carriers support those codes. Contact your carrier and ask how to set up call forwarding.


For example we use Spusu and Lebara MVNOs. The latter accepts MMI codes and I can forward to voicemail number, but the former sets up forwarding in their app, and voicemail does not have a number.
