We both work for O2 so have o2 sims. She does however have a tesco sim card in the second slot so if it's network dependent then I guess her Tesco sim is giving the option for wifi calling even though the signal provider is o2 🤔 ... View more

It uses WiFi to make phones without having to use 3rd party apps like WhatsApp or Messenger. Alot of my family don't have smart phones. ... View more

Yeah they told me the same. They did say they would send a £25 voucher that I actually received just now. ... View more

I pre ordered the S7 plus which was supposed to come at 12pm today. I phoned Samsung and they said there was a problem with the System. They said to expect it between now and Monday. They also said they will refund the postage and send a £25 voucher. Really disappointed but nothing we can do about it. ... View more

Nice TV Band 😁   Sounds like you have a very good up yourself. Again thanks for giving me a insight into what I could do to sort this issue. Its unfortunate Samsung doesn't have this quick switch option on their devices when others do.    I do have a Smart Things hub coming soon as we Switched to Bulb Energy through the Samsung Members app so I might see if I can hook then up through this or get some more expensive bulbs that do run through a hub.    Have a great weekend Brother.      ...

Hello Band of Brothers,    Thank you very much for the reply. I kind of thought there wasn't a option on my Ultra to switch as I can usually find a setting even if it's hidden away. I think you understand what I'm going to explain.  I bought some Smart Bulbs which don't require a hub to run but for them to work via the app that you install to control them the device you use must be on the 2.4hz connection.  When I tried to pair with the bulbs it recognised that my phone was on 5.0hz so thought I would try my tablet (again no option on my S6 to switch between frequency) but that was also on 5.0hz  I'm with Plusnet so I logged into my router and found what devices were on what connection. My Nvidia Shield & Samsung TV were on 2.4hz (think because the are connected via ethernet). The rest of our devices (Ultra, A71, Tab S6, Tab S4 and few devices we still have but don't use anymore) were all on 5.0 I spent a good hour see if I could manually swap my Ultra over to 2.4hz but the was just no way to do it. Google didn't help and I haven't heard back from Plusnet.  The only thing I could do (which you didn't recommend) was to turn the 5.0hz off totally thus reconnecting all our devices to 2.4hz. Doing this did allow me to configure the bulbs but it was a real mission.  We don't seem to have noticed any difference on our devices (maybe a slightly slower connection) being on 2.4hz so I guess this kind of solved my problem. Maybe I'll look into getting a proper hub which would take all of this manual connection out of the equation.  Anyway if you can think of another work around that springs to mind the please let me know.  Have a great weekend.    ...
