My device is Samsung galaxy A15 5g make and model is SM-A156E/DS and I'm trying to activate my voicemail on my phone and it is keeping asking add voicemail number and when I try to add my mobile number it just stays there but call are not going to voicemail and the voicemail is not activated yet. I need the voicemail because I do night shift if some calls me they can leave a voice not to my number so that I can check if that call is important or not. Let me know how to activate voicemail on my device. Need the response fast and quick resolution.
