I am an iPhone neophyte and am getting ready to head to PDC in 5 weeks. With my Verizon Blackberry, I simply added the international data plan and I was all set. Now I'm with Sprint and I have to pay by the kb. I've searched google and played with my phone and I see several settings, but I'm not sure which one to choose. I want to use the wifi at the resort and possibly have my phone work for emergency incoming calls from the US.
Any help with these options:
Airplane Mode - I don't think this allows WiFi
Data Roaming - My phone is defaulted to off and I think that should keep me from incurring data charges in Mexico, right?
Voice Roaming - keep on?
Cellular Data - this is the one that has me confused.
If I leave Cellular Data and Voice Roaming ON, but turn Data roaming OFF, would I be able to make/receive calls and texts but not incur data charges?
Thanks for the help - I don't want to come home to a huge cell phone bill!!!!!
