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.
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.
No they don’t. GSM is all over the place with frequency, but it never goes down to 118-137 MHz which is where air traffic sits. It’s just that mobile phones will increase transmission power to reach cell towers and that can produce that annoying disturbance. Phone won’t mess up instruments, just annoy people trying to talk and get your ass safely from the ground.
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.

I don’t think it’s an issue anymore though.

Mine had it disabled by default, but still available for emergency calls, and the option to enable it.
Mine has it disabled, but available if I want to enable it (with a security warning.)
