Delay on voice during calls after a few minutes.

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
