There are a number of ways to carry a cell phone. Let's first consider whether or not you're the type who likes to both make and/or take calls while out riding and those who don't.

FOR THOSE WHO LIKE TO MAKE AND/OR TAKE CALLS

1. Put your cell phone in your jersey pocket, belt or waistband clip, or pants pocket.
2. If there's rain in the weather forecast, put it in a ziplock bag and put it in your jersey pocket.
3. If not #1, put it in front basket or bag.

FOR THOSE WHO DON'T ACTIVELY USE CELL PHONES WHILE RIDING

1. Turn cell phone off.
2. Put cell phone into a ziplock bag.
3. Put bagged cell phone into bag or storage area of choice. (e.g. seat bag, handlebar bag, backpack, messenger bag, camelbak trunk bag, panier,etc)


All of these are possibilities. When I ride, I regard the cell phone as a tool for safety or emergency purposes. I put mine in a ziplock bag and put that into a trunk bag on most of the rides I take. For others, I put it into a holster and clip it to my belt or waistband. When I'm not riding, I either carry it in the holster or I leave it on my desk at my home.
