SMS over Wifi Calling

Hey everyone. I have some fantastic news to share on a network functionality customers have been asking about for a while. We’re excited to confirm that we’re now expanding the Wifi Calling capability to also work with SMS. This means customers who are using Wifi Calling will also be able to send and receive text messages over a wifi network if they are using a compatible device.

 

What devices and when?
The service launched on select handsets on 10th January 2022 and we’ve been monitoring the stability first before announcing it here on the Community. Right now the service is only available on the Samsung Galaxy S20 family – the regular S20, S20 Plus and S20 Ultra.

We will be rolling out capability to more handsets but cannot confirm exact dates at this time.

How do I activate the feature?
Customers with a compatible device will need to have the Wifi and 4G Calling service provisioned on their account and will need to update their device to the latest software version.

Note that the update for the S20 family of devices will come in the form of a ‘System configuration update’. Your device will notify you when the update is available, and you will be asked to apply the update. The device will then restart, and the update will be applied. At this point, SMS over Wifi Calling should now work as expected.

Why can’t all current Wifi Calling handsets support SMS over Wifi Calling?
Each device that supports Wifi Calling today will need to receive a software update in order for SMS over Wifi Calling to work. There are some handsets we support today that are now too old to receive software updates and therefor will not become compatible with SMS over Wifi Calling. Newer devices will receive updates, but it will take time for the manufacturers to develop and release the software, for which we have no further details or ETA – but we’ll continue to work closely with manufacturers to help implement this.

I’ll update this thread as and when new devices become compatible with SMS over Wifi Calling.

Can we get an updated list of confirmed working devices @Chris_K ?

Anecdotally there seem to be more phones, and different manufacturers, than the original post but no confirmation?

Hi Chris,

I have moved home into a one bar signal area (December 2022).  I have linked my iphone8 calling to the O2 network by wifi to my router and that is fully working.  My problem is that I do not receive SMS messages, or at best hours to days later.   Is this because my iphone is rather old and hence non-compatible with wifi?  Software updates are not a problem.  Looking forward to your reply (much appreciated)!  Andy

No, sorry

I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
Please select the post that helped you best and mark as the solution. This helps other members in resolving their issues faster. Thank you.
