eli5: Why is there a -no mobile phone- sign at gas stations?

Question

There are always signs that show the ban of cigarettes, matches and phones at gas stations. I can imagine fire being dangerous around gas, but you can’t possibly blow up a gas station with a mobile phone, can you?

I first started noticing them pop up after there was a rash of cellphones spontaneously catching fire on planes. I imagine they’re mostly safe these days
