My daughter will be heading to South Africa to study abroad for 4 months. We don't want additional charges. What settings do I need to change on the phone to ensure that we are not being charged at all? Is turning on Airplane Mode enough?
She is still interested in texting and possibly calling. We've heard she could do that by using certain apps on wifi only. Is this true? Are there apps you recommend?
Data roaming off and airplane mode on. Wifi can be turned back on. (So can Bluetooth). She could still call and text you over Wifi. She might want local service as well, which may mean swapping SIM cards.
