VoLTE and Wi-Fi calling

[Mikep100]

Hi everybody

I have a Note11 (great phone) but I am having problems with VoLTE and Wi-Fi calling

I am with giffgaff, an MVNO of O2

The claim that all users can utilise VoLTE and Wi-Fi calling and their list of compatible devices states ....

• Xiaomi Devices:
• All devices with a Snapdragon chipset.

My phone gives no option for either VoLTE or Wi-Fi calling

giffgaff say "It’s up to Redmi to release the update to enable their phones to work with giffgaff’s implementation of WiFi calling."

My specs

Any help please ?

1. Enter the string * # * # 86583 # * # * in the field for dialing numbers, a message will appear after the last character, which must end with DISABLE. If ENABLE, we repeat the string again. This will allow VoLTE because this menu is hidden by default.

2. Enter the string * # * # 869434 # * # * as above, again the message with DISABLE must appear at the end. We have enabled VoWIFI.

Thanks for the rapid reply
Checking is turned off for bot but sill no option for VoLTE or Wi-Fi calling

And have you toggled the VOLTE and VOWIFI switches in the SIM settings?

Not available I am afraid

Then you probably activated the switches incorrectly. Try again.
Or your SIM does not support it.

 

[Mikep100]

I have tried it several times so far

from giffgaff's list of supported devices at https://www.giffgaff.com/help/articles/wifi-calling

• Xiaomi Devices:
• All devices with a Snapdragon chipset

Are they incorrect ?

 

[gogocar62]

If you entered the above codes in the dialer, do you see this message?

 

[Mikep100]

Definitely - as in post 3, in both cases the check disabled message appeared.

and to check, I enabled them and then disabled them again

 

[Mikep100]

There is a suggestion from giffgaff that Redmi (Xiaomi) have to update my software/firmware

 

[Mikep100]

Update

The giffgaff sim in my wife's iPhone 12 Pro is now using both VoLTE and Wi-Fi calling

So the problem seems to be with Redmi Note 11's implementation of VoLTE and Wi-Fi calling

Update 2
Just used my giffgaff sim in an old iPhone XR and it is happily using Wi-Fi calling

 

[Mikep100]

I have, incidentally, just noticed that I am on Android 13. I have tried to upgrade but phone says it is on latest version
So why has it not upgraded to 14 ????

This device will be EOL in early 2025 and will not have A14.

 

[Mikep100]

?????????????????????
Are you telling me that the "current model" mobile phone that I bought is now a brick after less than 2 years ????
Way to go Xiaomi. I now know not to trust their update promises
.............. and still it won't handle VoLTE

Oh well back to Motorola

 

[NOSS8]

 

[Mikep100]

Sadly, not what they told me at the time. Mine was shipped with 12, with a promise of 2 updates

 

[Mikep100]

Still no ideas as to why the Note 11 can't use VoLTE ?
