Hi there ​@Milo123, sorry to hear that. How long have you had issues for? What phone do you have?

Thanks,

Tyler

Since I joined IDmobile  iPhone 16 

I have WiFi on but doesn’t work with WiFi calling I’ve got 2 bars of signal but still can’t call out or receive calls 

I just get text telling me I had missed call with the number that called or voicemail 

which has been annoying as been waiting for call from Doctor  so I just phone up and see if the doctor has phone me yet !!!!!

Hi ​@Milo123  can you try the following troubleshooting as recommended by Apple?

1. Disable Wi-Fi Assist (if enabled):

• Go to Settings > Cellular
• Scroll down and turn off Wi-Fi Assist
• This prevents the phone from switching to weak cellular networks automatically, which can interfere with Wi-Fi calling in low/no coverage areas.

2. Toggle Wi-Fi Calling Off and Back On:

• Go to Settings > Phone > Wi-Fi Calling
• Turn Wi-Fi Calling off, wait 10 seconds, then turn it back on

3. Check Date & Time Settings:

• Go to Settings > General > Date & Time
• Ensure Set Automatically is enabled
• Incorrect time sync may cause call routing issues over Wi-Fi.

4. Confirm VoLTE and Carrier Settings:

• Go to Settings > Cellular > Cellular Data Options > Voice & Data
• Make sure VoLTE is enabled (if supported by your carrier)
• Some networks require VoLTE to properly route Wi-Fi calls.

5. Reinstall iOS via Finder/iTunes (optional advanced step):

If the issue persists, doing a clean install of iOS 18.5 via Finder (Mac) or iTunes (PC) may help resolve potential update-related software issues.

Please let us know how you get on.

Can’t find VoLTE on my iPhone think I’ve done all the other things mentioned

ill let you know how I get on 

Hi I’ve tried all the things suggested but still can’t make or receive calls 

only way I know some one phone is when I get a text saying missed call 

am disabled and need my phone to be working 100%

Hi ​@Milo123 

I’d recommend trying the above from ​@WelshPaul, that can fix a lot of common issues.

Please let us know how you get on.

Hi I’ve done what ​@WelshPaul  has suggested but still the same 

if I switch off my wi-fi I can make a call not sure about receiving as no one phoned 

at home am always contacted to WiFi 

I was suppose get a call from ID technical but as I told the lady am not receiving calls either !! 
looks like I’ll have to get in contact with the place I got the phone etc from 

If you’re able to make a call after switching off Wi-Fi, it sounds like your ISP or router is having an issue with Wi-Fi calling.

I don’t have WiFi calling on or dial assist ? 
WiFi was working fine with my other provider EE and my partner is having the same issues as me and worked fine before he was with 3 

my son phone works perfect in the house his with EE 

You mentioned in your above replies that you have it enabled?
 

Wi-Fi calling isn’t standardised across networks, as they all operate differently. They often use different ports and protocols. However, it’s rare for Wi-Fi calling to fail to work. I’ve only seen it fail a handful of times, often due to people using old routers or business-grade internet connections with strict firewall policies. 

Make sure Wi-Fi calling is off:

Settings > Apps > Phone > Wi-Fi Calling > Off

This one should be on by default:

Settings > Apps > Phone > Dial Assist > On

Check you have signal and try making a call. Mobile number should start 07 and a landline 01 or 02. 

Morning. I think resetting network settings has fixed my problem I can make and receive calls so can my partner 

thanks so much for your help everyone 

Hi think spoke too soon  sitting here working and just get a text  saying phone voicemail I had an important call that went straight to VM. ? 

Hey there ​@Milo123, are you still having issues please?

Thanks,

Tyler
