Disable iPhone Cell Antennae

Solution 1:

Put your iPhone in airplane mode then switch wifi on.

Solution 2:

Three methods will work:

• AirPlane mode and then enable Wi-Fi
• Pull the SIM chip
• Disable cellular data in the settings app.

These are listed in the most true to your initial intent of not having the antenna operating. I like the middle one as a good tradeoff between not talking with cell towers but maintaining GPS capabilities to tag pictures and use the map with tiles present from WiFi. The battery drain on the second two are more than the first, but still pretty usable in general on the later iOS versions.

Clearly, you can't pull a SIM if you have a phone without one, but the other options work with all iPhone models.

Solution 3:

The best way to do so is to turn on Airplane mode. This will turn off all cellular and data sercices, but you can then turn Wi-Fi back on.

You will have Wi-Fi and your phone will not connect to the cellular network until you turn off Airplane mode again
