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

Hi @Christo_3322266 

Have you checked to see if your phone is supported for VoLTE on their network?

Here is some info I have found with regards to this:-

If you can't make regular or WhatsApp phone calls,it could be due to several issues, including network problems, app glitches, or device settings.Here's a breakdown of potential causes and solutions:

1. Network Connectivity:

• Check your signal: Ensure you have a strong and stable cellular signal or a reliable Wi-Fi connection.
• Restart your modem/router: A simple restart can sometimes resolve network issues.
• Check for outages: If you're in a specific area, your mobile network provider might be experiencing temporary outages. 

2. WhatsApp Issues:

• Update WhatsApp: Make sure you're using the latest version of the app. 
• Restart your phone: This can help clear temporary glitches. 
• Force quit and reopen WhatsApp: This can sometimes resolve app-specific problems. 
• Check WhatsApp permissions: Ensure WhatsApp has the necessary permissions for microphone, camera, and audio access. 
• Check your phone's settings: Ensure that WhatsApp isn't blocked by your phone's firewall or security settings. 
• Check your microphone, camera, and speakers: If you're on a computer, make sure these devices are working correctly. 
• Contact WhatsApp support: If the problem persists, reach out to WhatsApp Help Center for further assistance. 

3. Device Issues:

• Check for software updates: Ensure your phone's operating system is up to date. 
• Restart your phone: A simple restart can resolve temporary glitches. 
• Check for device settings: Verify that Airplane mode is not enabled and that your phone isn't blocking calls from unknown or private numbers. 
• Check your SIM card: Ensure your SIM card is properly inserted and not damaged. 
• Reset network settings: This can help resolve issues related to network configuration. 

4. Other Potential Issues:

• Conflicting apps: Make sure another app isn't using your microphone, camera, or audio. 
• Battery saver mode: Turn off battery saver mode, as it might be restricting certain functions. 
• Check your account: Ensure you have an active account with your mobile service provider and that your bill is paid up. 
• Contact your carrier: If you're still having trouble, contact your mobile service provider for further assistance. 

Good luck x x

@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?
