Dan's Samsung Galaxy S21 Ultra keeps defaulting to cellular preferred, instead of WiFi preferred. But instead, he's missing calls and texts as a result. He uses T-Mobile. The cellular is a bit sketchy in his area, so he'd rather use WiFi Calling. But the phone won't let him. Leo says that if he gets out of range of the WiFi, it'll immediately go to cellular. Dan says it stays that way, though, when he's back home. Try rebooting the phone. Often that fixes the problem.
Vicky has a problem that she can't have a cellphone conversation unless she goes outside. It works for a few minutes and then begins to break up unless she goes outside. She's also having buffering issues with her TV streaming. Could they be related? Leo says they could be. Modern cellphones have a WiFi calling feature, where the phone routes the cell phone call through the internet. You can disable it in your phone settings. But that doesn't solve your buffering problem, and that points to a bandwidth issue. What Vicky needs to do is find out what her bandwidth speeds are.
Andrew wants to know how different Spectrum mobile is from Verizon. Leo says that Spectrum Mobile uses WiFi calling when users are home, but when users are out and about, Spectrum is just an MVNO that uses Verizon's network. The tricky part is a handoff from WiFi to the cellular network. But other than that, if one can save money on it, then why not? The only real negative is that some people may not have internet access with their routers. So, a phone could join a network and not be able to take or make calls because it's on a dead connection.
Robert bought the Alcatel A621 Pixi Glory phone. What he hates is, he keeps getting upgrades to his phone and he's starting to run out of space. Leo says that upgrades are supposed to upgrade in place, overwriting the operating systems, not maintaining multiple ones. Leo says that there isn't a huge amount of storage because it's a cheaper Android device. Eventually, he won't be able to do anything because he will run out of space.
Tom bought an unlocked Samsung Galaxy S9 while he was travelling and now that he's back, it won't support WiFi calling. Leo says that Verizon supports VoLTE, so contact Verizon and ask them to turn on HD Voice. Tom can also turn it on with the MyVerizon app or the Verizon Account page.
Leo was down in Marina Del Rey this week, and got to ride around Marina Del Rey on an electric bike for rent. When you're done with them, you just leave them where you go. Leo says it was pretty cool and the cost wasn't that bad. Johnny Jet says that some cities are starting to limit or even ban them because they get left everywhere and can be a hazard. He was in San Diego and saw them lying around everywhere.
Gary has a Motorola G5 plus mobile phone with T-Mobile and after his phone updated, his WiFi calling option won't connect. Leo says the culprit is that the update broke that feature, and it is only a matter of time before Motorola puts out a fix. Leo says that his router may also have an issue with it. He may need to log into the router through the browser and reenable port forwarding or open port option with UDP enabled.
Milan has a OnePlus 6, but his carrier, AT&T, doesn't support voice-over Wi-Fi with it. Leo suggests a microcell, or femtocell, and tell them he's moving to another carrier if they don't give it to him. Another option is to use an app like WhatsApp or Google Voice to do it. According to the chatroom, it has to be an AT&T branded OS to support that feature.
Here's a list of the phones AT&T supports with that feature. (Thanks ScooterX)
Neil traded up his iPhone 8 Plus to the iPhone X, and he wants to know if Wi-Fi calling is a good idea. Should he turn it on? Leo says that the cell carriers would like him to use it if they support it. It doesn't use their towers, eliminating congestion, and they can still charge him for usage. Would it be of any benefit to Neil? Leo says not really. Quality will vary and if he has a poor connection, that could be an issue.
Tina wants to know if Verizon has improved their call quality. She left because it was so bad. Leo says that thanks to VoLTE, (Voice over LTE), the call quality has improved remarkably. Additionally, some carriers also support Wi-Fi calling, which has fantastic call audio quality. Most carriers offer two week trials where if you don't like the service, you can return the phone and cancel. So give Verizon another try. The quality has improved.
