forwarding voicemail with *004* results in "Call forwarding Connection problem or invalid MMI code"
On my old Android phone and plan, I used to be able to forward my AT&T voicemail to Google Voice with the MMI code *004*1234567890# (replace 1234567890 with my google voice number), now, with my new plan, the same code results in an error. "Call forwarding Connection problem or invalid MMI code"
Searchin online for this error yeilds people having to call AT&T customer service to unlock their Voicemail Conditional Call Forwarding. I tried calling but was on hold for an hour and gave up. Is there a solution that doesn't involve trying to get a human on the line?
