Episode 1831

Alac from Irvine, CA

Alac has a Samsung Galaxy S10, and when he tries to use maps, it drops the data connection. But only in cellular, not on wifi. Leo says that location data is done in three different ways ... GPS, WiFi triangulation, and cellular triangulation. It's possible the settings in the phone have it looking for a wifi connection due to wifi calling. Turn that option off, and see if it works. Also, look to see if those apps have "allow cellular data" enabled. It'll be in the app settings.

Dan from Atascadero, CA

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.

Cell Reception

Episode 1779

Vicky from San Diego, CA

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.

What's the Difference Between Spectrum and Verizon Cellular?

Verizon

Episode 1755

Andrew from Los Angeles, CA

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.

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.
