Hi:
In fact I bought it and returned it in one day as it did not have the WIFI calling feature. So, I may not be able to help you in that way.
Thanks

Same problem here. Will we ever see OTA update?
Nvmkpk:
I have not checked first hand, but my understanding is that the setting to toggle Wi-Fi calling on/off would be visible only on EE/T-Mobile USA software SW variants, and it's not possible to use the feature on an unlocked phone with EE/T-Mobile SIM-card.
Does this mean wifi calling will work on an unlocked (unbranded) Lumia 640 with T-Mobile USA sim card?
Hi armagon,
I obtained my Lumia 640 from EE in the UK on 20th May 2015, and it came with Windows Phone 8.1 Update 2 "out of the box" and also featued WiFi calling.
My current version is 8.10.15145.156 and I currently have no updates available.
Should I now expect to receive a further update to the latest release please?
Thanks!
