getting 'call failed' whenever answering incoming call, and nothing happens when I call out.

[Christo_3322266]

This is urgent! I cannot receive or make calls. 

Any incoming call I get, when I answer it I immediately get call failed on my iphone.

Has been like this since yesterday. Neither can I use Whatsapp for incoming or outgoing calls.

I can text successfully.

I'm going on holiday on Saturday morning and I need to be able to contact my son whilst I am away.

I am 4G and voLTE enabled.

Can you please advise?

Thank you,

Chris

@Christo_3322266 Did you start by doing a Network Status check to look for any local problems?

Can you check the phone with another sim from a friend/family member?
