Sometimes the interference seen on those maps does affect phones, sometimes it doesn't.
Coincidentally there's a huge region of GPS (at least) interference this week over the New Mexico area, from a military test. My guess is that people on the ground won't be affected, unless maybe they're very close to White Sands Missile Range between 18:30 and 22:30 GMT.
