He didnвЂ™t come up with the tune and load it on his phone, the phone came with the tune and he added the words and claimed it as his own.

Instead of coming up with a jingle for his tile business he added some words to go along with his favorite pre-loaded ringtone on his phone. Early on, mercenaries are chomped and/or stomped by a huge Spinosaurus (this sequelвЂ™s largest, most intimidating species).

Two men disappear from the deck of a boat (implied deaths, blood stains). So, before giving it to Udesky Kirby customized it to his favorite ring tone, hence why it rings with that tone while Udesky is at the demolition range.ДЄlso a side aspect to this theory, Paul Kirby is a cheap lying bastard. When their plane crashes and they become stranded, they discover the islands native inhabitants are smarter, faster, fiercer and more brutal than imagined. Intense action violence ranges from a plane crash to people being traumatized by angry dinosaurs. If this is the case it makes sense heвЂ™d give it to Udesky since heвЂ™s in charge of putting together the supplies for the trip, packing, testing, etc, and since Udesky is doing back and forth communication with Kirby while getting ready why not use the Sat phone as a means for communication on his end. So, Paul Kirby bought this phone specifically for the rescue trip. He was tired, thirsty, and hungry, but this tough guy seemed to be in decent shape for having survived a plane crash and a few days in the Arizona wilderness, ArizonaвЂ™s Department of Public Safety wrote in a press. HereвЂ™s how it goes, Paul Kirby wouldnвЂ™t have had any reason to have a satellite phone for regular daily life, no real reason to carry it around regularly since a standard cell phone would be fine for use in the continental US. The pup fled the area again when the helicopter landed, but crew members used water to lure him back and get a leash on him. This is not a canon explanation by any means and is just a work around I came up with in my head.
