A cell signal can set off an IED. Especially when you're dealing with blasting caps

Cell phones dont set off blasting caps. Blasting caps use less than stable materials, however static is more of a concern than cell phones.
The blasting circuit can behave like an antenna, much like the antenna for a radio, and can convert electromagnetic waves into electrical current. If sufficient energy is created, the detonator(s) can function. A number of factors need to be considered: the length and arrangement of the detonator and extension wires and their relative angle to the waves (efficiency as an antenna); the power of the transmitting device; the distance between the transmitting device and the blasting circuit; and the frequency that is used by the transmitting device.
The AM and FM radios in cars are receivers and do not constitute a hazard. Cellular phones pose a unique problem in that when they are turned on but not in use, they are interrogated several times per hour by a cell transmitter to determine whether they are within the range of the cell and if they are on. A cell phone that is turned on replies and this may pose a hazard.
Accidents have been attributed to transmitters being too close to the blasting circuit.

Blasting caps placed outside before the explosives (even overnight) would have a very very high chance of being duds by the time you place the explosives. Anyone even slightly trained in explosives would know that.
