Ive just bought an S7 a few hours ago. Its coming up Voicemail Number Unknown, when i click it already has 901 in it i cant change it to anything else to change it back to 901. Ive cleared the phone data and cache and it goes untill i restart the phone and it appears again. Ive tried dialing 1750 and 1760 but when i do it just beeps a few times and disconnects the call.

So if you dial 901 it says "unknown number"?
Have you still got old iPhone?

I changed the voicemail number to 123 and saved it. Then I changed it back to 901 and saved it and it seemed to do the trick. This is on a Samsung s9+.

That fixed it for me too. I changed it to 123, clicked OK, then changed it back to 901 and clicked OK again.

There had been a voicemail from "Private Number" but when I listened to it, it was just a muffled voice with background noise.
