I'm traveling to Tanzania next week with my Iphone 4s. I plan to use just the WiFi but would like to have access to phone only if there's an emergency. I've been reading the posts about travel and am confused as to how to limit roaming costs.
- Do I turn both Cellular Data and Data Roaming off?
- Do I go use Airplane Mode with Wifi on?
- Also will I be able to make a phone call in Tanzania if there's an emergency?
Sorry about repeating a common question.
