WiFi calling

[#1]

Am I supposed to make changes in the router to enable wifi calling from my mobile?

I'm on giffgaff, they use O2 & the signal here ME10 1DB is very poor. I've enabled wifi calling on the android phone but it has made no difference, I read somewhere else that I may have to alter the settings in the router to make it work, the router is a Hub1.

Advice please

Would it be any better on EE?

@bertmay (1) I don't know where you read about 'making changes on your router', but wherever it was, was wrong.

                  (2) Changing phone network providers will make no difference to the quality of your WiFi calling signal.

Both the above comments are based on my understanding of the technology - someone with more knowledge may wish to prove me wrong. 😉

@jab1 I think @bertmay meant his normal phone signal was bad.

WiFi calling certainly works for me (I just tested it calling my landline) using GiffGaff and PlusNet (FTTC with Hub2).

Note I am using an iPhone and when you turn this feature on you can see it at the top of the screen.

No idea about Android though so this may suggest a problem with @bertmay phone ?

Note that I don't normally use it; I just turned it on and it worked.

That's what I thought about point 1

The o2 coverage here is poor with giffgaff.

Just looked at EE coverage map & it is supposed to by better & allows wifi calling, as it seems most do now.

I get the wifi symbol at the top as well, Motorola g14

@HPsauce I too use an iPhone (12) and have had WiFi calling enabled for a few years (with Smarty and now iD, both on the 3 network), and have had no issues.

@bertmay  From your posting history you've been with Plusnet for many years so you may still have the Broadband Member centre Firewall enabled in your account. It's on the add-ons tab in the member centre, I think it has been removed or defaults to off for newer customers. It must be set to low or off. Higher settings block the IPSEC protocol used for wi-fi calling. The firewall is a throwback to the days of dial up modems and is not needed any more when routers with their own firewalls are used.

Worth checking, it does catch users out sometimes.

Which which Android version are you on ?
Even though the network supports WiFi calling it is dependent on the phone and android version being "supported".
Some older phones don't play well with WiFi
calling. I had an issue with WiFi calling on EE with an older android 10 phone. Updated to a newer phone android 15 and all worked well.

Here’s the situation with Wi-Fi Calling for the Motorola Moto G14 on giffgaff UK:
📶 1. Giffgaff UK Wi-Fi Calling Support
Giffgaff does support Wi-Fi Calling and VoLTE (4G calling) for compatible phones if both the phone and firmware are supported.
help.giffgaff.com
Giffgaff’s published compatibility list currently does not list Motorola phones (including the Moto G14) as supported yet — it shows only a placeholder entry and mentions awaiting firmware availability for Motorola devices. �
help.giffgaff.com
Community reports also suggest that Motorola phones on giffgaff often lack the Wi-Fi Calling option in settings, likely due to this lack of carrier provisioning / firmware support — even if the hardware could support it. �
community.giffgaff.com
📱 2. Moto G14 Technical Capability
The Moto G14 runs Android (originally Android 13) and has VoLTE support according to some carrier specs. However, Wi-Fi Calling isn’t clearly indicated by Motorola for all variants/carriers. �
devicesupport.three.co.uk
Motorola documentation explains that Wi-Fi Calling availability depends on carrier support and provisioning — if your carrier hasn’t enabled it for your phone build, the menu and functionality won’t appear. �
en-us.support.motorola.com
✅ What This Means for You on Giffgaff UK
Right now, the Moto G14 likely will not show or support Wi-Fi Calling with a giffgaff SIM because giffgaff has not confirmed firmware support for Motorola devices.
You might see the VoLTE setting (so normal 4G calls may work), but the Wi-Fi Calling toggle may be missing or greyed out. �
community.giffgaff.com
This isn’t a fault of the SIM or phone alone — carrier provisioning/firmware is required for the feature to appear and function on Android phones. �
en-us.support.motorola.com
📍 Tip
If you need Wi-Fi Calling reliably, you could consider using a network that officially supports VoWiFi on Motorola devices (e.g., EE or O2 directly), as those often have clearer carrier-firmware support — but this depends on your exact phone model/region.

Works OK on unchanged Hub 2 router with Moto g06 phone (Android 15) and Tesco Mobile (O2 carrier). Also, this is a PAYG phone.
It's my default phone mode when at home, as carrier signal from base station is very variable.

(my bold)

OT, and things may have changed (IDK), but be aware that iD seem to have more than their share of SIM fraud and number hijacking, leading to identity fraud etc. - e.g.  iD mobile vulnerabilities

[#11]

Thanks for the 'warning', @RobPN , but I (A) know a number of people on iD, and none have reported issues, and (B) I've been around long enough to be aware of what could happen. In any case, my phone is primarily used as a phone - very little sensitive data is stored on it.

[#12]

Fair enough @jab1 

I first became aware of how easy it is/was to 'change ownership' of an iD mobile number without the legitimate owner being aware after a friend told me a year or so ago that it had happened to him.  He only became aware when the police / action fraud investigated after some financial losses, including a loan being taken out in his name, had occurred. The iD SIM was his secondary number which is why he wasn't aware for a while that it had been hijacked.

[#13]

The unasked question here is does the mobile service provider facilitate WiFi calling?  This is neither an ISP service or mobile phone carrier question.

Plusnet mobile used EE as the network carrier.

Plusnet mobile users could not use WiFi calling.  Native EE users can use WiFi calling.
