Cell phones have become a remote detonator of choice for terrorist groups the world over. Explosions can be triggered from a distance by calling or texting the number of the phone

Texting has nothing to do with it. Calling the number is what sets it off.

Anything that sends a signal to the speaker/ringer on the phone will trigger something that’s attached to it. Some phones can be set to make a special sound when getting a text message. The bomb, of course, does not care whether it was a text message or an incoming call that caused the phone to sound.

The ring tone sets it off which can be from text message or a call.
