Cell Phone Use

I have question that I was hoping someone can clear up for me. I was watching the show on sun network and notice that cell phones were being used during tourment times. I was under the inpression that no team member is allowed to use cell phone or radios to talk about fishing. I was just wondering because it sure would be nice to use to the talk to my other team members when we are all split up wading different areas. If someone would clear this up I would apprecate it.

Teams may use phones or 2 way radios to communicate with each other, but not other teams
