Old thread, new update. Did La Zona with a new Verizon iphone for the first time. Outgoing calls will show an "Out of Area" message to the receipient. Out of Area implies out of the U.S.. For those of you calling a S.O. or Boss, this could raise issues. As soon as you're back on the San Ysidro side, it will go back to regular roam and not show the "Out of Area" message. I always carry an emergency back-up pay-per-minute phone, so I tested it to myself.
Also, iphone had significantly better receiption from my last smart phone. No issues from inside the Cascadas, Rizo de Oro, or on Revolucion as I've experienced in the past.
Hope this helps?
