In my country, 2G phones could interfere with radios with that da-dada-da-dada sound. I know people who have personally had that happen to them while trying to land airliners and it made listening to ATC more difficult.
I don’t think it’s an issue anymore though.
That's because phones and airplanes were operating on the same frequency. They don't do that anymore... in part because there's a dozen phones on every flight that haven't been put in airplane mode.
Definitely not an issue in the US anymore. T-Mobile is the last carrier to support 2G and they're shutting that down in April this year. I think most Android phones explicitly disable 2G now too because it's not secure.
Mine has it disabled, but available if I want to enable it (with a security warning.)
Mine had it disabled by default, but still available for emergency calls, and the option to enable it.
