iPhone: Turn Off Phone Network and Data But Keep WiFi On

When you are traveling to a place where your carrier would charge exorbitant prices for data, text, or minutes you may want to disable all phone, text, and data on your iPhone. But you also want to keep Wi-Fi working. It’s a really simple, two-step process, all under Settings.

1. Turn on Airplane Mode. This will turn off phone, data, text, and Wi-Fi.
2. Turn on Wi-Fi. Your phone, data, and text services will remain disabled. But you can still iMessage when you’re connected to Wi-Fi.
