[Q] How to change my voicemail number?
Any one knows how to change my VM automatic Dial number? When I flashed using Odin, it shows that it's unknown, however If I try to add it it asks me to contact my phone provider... which has nothing to do, since they only provide the SIM card,
What's strange is that, if I install any ROM then the phone will work fine and recognize all service numbers that it should, it only happens if the original fw is installed.
P.S My phone is a Samsung Galaxy Ace S5830L, but it's the same as the rest of the Ace's.
