    This is the list one the Smarty website and your phone is not showing as being supported by Smarty currently.

    I can see that it is supported on some networks. Worth checking that page regularly to check if it has been added. That said, it is not a cast-iron guarantee that it will work - others on the forum have complained about some phones not working on wifi calling despite being on the list.

        Well, that's what the printed list says, but I guess you wouldn't know for sure until you tried it with your sim.

        Unless you know a friend/family member who has one, that could be a problem I suppose.

    Unfortunately Defiant1337, SMARTY Mobile and their parent Three UK are woefully slow/inefficient at keeping lists of compatible devices up-to-date. 

    Nevertheless, if Three UK are selling this handset on contract, it's safe to assume it'll work with VoLTE (4G Calling). Likewise for WiFi Calling service - useful if you've got a poor signal indoors at home.

    Three UK are currently turning OFF their 3G network across the UK - works are scheduled for completion by end of 2024. Without 3G your handset must be capable of 4G Calling (VoLTE), otherwise you won't be able to make/receive calls on your mobile phone. VoLTE and WiFi Calling go hand-in-hand, as they both rely on your mobile network operator's IMS back-end technology.

      My phone does say its connected (icon of phone and wifi) but people complain of really bad call quality to the point I have to spend most of the call repeating myself and shouting, before this I had an iphone 13 pro max and calls over wifi were fine

        Maybe you can tweak the IP settings on your Wi-Fi router to improve the call quality over Wi-Fi Defiant1337.

        I rely on the WiFi Calling service at home, living in a mobile not-spot. Call quality can be variable sometimes, and I've found just changing position slightly can have a dramatic impact.

        With so many using IP telephony these days, without necessarily using properly optimised setting on their VoIP networks, call quality could suffer.

        Finally, I can't help feeling Samsung are more interested in the photographic capabilities of their premium handsets, which means call quality plays second-fiddle. My daughter and wife use Galaxy S10 handsets, which are more than good enough for pictures, et cetera, yet deliver an excellent call quality.

        Have Samsung lost their way - smartphones still needs to make telephone calls?
