Once planes are far away from telephone towers, mobile phones tend to send out stronger signals in order to connect with the closest possible one.
It is true that they do this by using frequencies, but they don’t necessarily put a stop to communications between pilots and ground staff.
Instead, the signal can cause a high pitched beeping sound which pilots pick up in their headphones.
While it might not put a stop to important instructions, it can certainly be irritating.
