Hi ​@cjd007, 

 

Thanks for getting in touch I’m sorry to hear you’re having issues with call delay, I know how disruptive that can be.

From what you’ve described (calls starting normally, then developing a delay/people talking over each other), this is typically related to VoLTE (4G Calling) switching, network registration, or signal handover issues, rather than a location-specific fault.

Let’s go through some steps to help stabilise your calls on your iPhone 16e:

📱 1. Check VoLTE / 4G Calling is enabled

• Go to Settings → Mobile Service → iD Mobile SIM
• Tap Voice & Data
• Make sure 4G or 5G with VoLTE enabled is selected

If VoLTE is off or unstable, calls can fall back to 3G/2G and cause delay issues like you’re experiencing.

📶 2. Toggle Airplane Mode (network refresh)

• Turn Airplane Mode ON for 10–15 seconds
• Turn it back OFF

This forces a fresh network registration and often clears call delay issues.

🔄 3. Reset network settings (you’ve not mentioned this yet)

• Go to Settings → General → Transfer or Reset iPhone
• Tap Reset → Reset Network Settings

📡 4. Check signal stability during calls

Even if signal bars look fine, call delay can happen if:

• The phone is switching between 4G/5G frequently
• Indoor coverage is weak and fluctuating

Try testing calls with 5G turned off temporarily:

• Settings → Mobile Service → Voice & Data → select 4G

Thank you for quick reply.

My Voice & Data setting only shows : 5G Auto (currently ticked) , 5G On or 4G

I have previously tried airplane mode toggle and network reset,

I will try 4G

I’ve not experienced this on other networks (O2, Vodafone) is this specific to ID/Three? 

Thanks,,

Chris

Thanks for your reply. I have switched off 5G and it seems to have fixed it. Calls just on 4G work fine.

Not a great solution when I’m paying for a top end latest phone and a 5G service. 

I’m hoping that another response will come from ID mobile with the option to terminate the contract if it’s something they can’t fix.

Hi ​@cjd007, 

thank you for the update. I’m glad to hear that switching to 4G has improved the calling issue.

That said, I completely understand your frustration, especially when you are paying for a premium handset and a 5G service and would naturally expect to use those features without issue.

At this stage, switching to 4G helps confirm that the issue appears to be related specifically to the 5G connection in your area or how the device is interacting with the network. This information is helpful for further investigation.

This could mean that 5G in your area is not very good.

Thank you for looking at this.

I experienced the issue in many locations when travelling in the UK.

The coverage checker shows there is no 5g service in my area, so I wouldn’t have expected any change by switching 5G off my phone. Maybe, there is a very weak 5G coverage and the phone is trying to switch unsuccessfully. 

Either way, it feels like there is something wrong somewhere and I’d really like to get it solved.
