Iphone 6 plus was working fine now can't get any signal

[pashtun]

Had the iPhone 6plus couple of days now was working great up. It's now not getting any signal and constantly searching for network. It's also making a weird sound when it vibrates. Have I got a faulty unit. I have no signal so cannot call Vodafone can someone please help.
