[BoroParmo]

Hi there,

Recently my calls have started going straight to voicemail and instead of a call Ive been recieving a message saying the contact called but didnt leave a message, does anyone know why this is, Ive looked at al the call settings and disabled anything that should be causing this and it stil hasnt helped

If anyone can help I would be greatful

Thanks

How good or bad is your network coverage? it'll be wise to contact your carrier/network regarding this, perhaps even getting a brand new SIM card.

Its pretty good, I always have signal its just I wasnt sure wether this might be a phone problem or a network problem but thanks for replying

Settings > about phone > status > signal strength

My phone is going straight to voicemail. I saw the response that suggetsed checking signal strength and this reads "-97 dBm 43 asu"... Unfortunately I have no idea what this means and si still have a problem! Please advise, someone!!

I believe the Qualcomm chipset that governs LTE + phone calls can go bad. It did in mine.
