WiFi calling not available

[keith1]

My 3 sim does not have WIFI calling anymore? it did have but not now. I have 2 sims in my phone one from 3 and one from tescos mobile. the Tescos does have WIFI calling. I have tried Airplane mode, rebooting phone/router etc.and still no good! I have a Redmi note 13 pro plus with all the latest updates As I have a very poor signal at home this makes my 3 sim virtually useless.

Hi @keith1,

Sorry for any  misunderstanding there, when I had read "I have tried Airplane mode, rebooting phone/router etc.and still no good!" It wasn't particularly clear if you had tried what I described or were simply toggling Airplane mode on and off quickly to refresh your SIM's connection.

I follow that the Tesco SIM is working for Wi-Fi calling, but we ideally need to clear up if the issue is the SIM, phone, Wi-Fi, or your Three number's provisioning on the network. Tesco don't use Three's core network, so although it's certainly helpful info, it doesn't pinpoint the issue.

• The recent SIM swap means the SIM is unlikely to be the cause. Just to confirm you had the same number swapped onto a new SIM, or did you try a completely new SIM and number?
• If you have any old, spare or can borrow a compatible phone from a friend or family member it would be helpful to check if the same issue happens in another phone with your SIM?
• Likewise, have you been able to test against other Wi-Fi networks, or only your home Wi-Fi?

Let me know if you're able to test any of the above, or if you're not able to test again just let me know here regardless. Once we've got this info together with the other info you've already shared I'll check how we can get this looked into further.

Thanks,
Jonathan
