Taking my IPhone from USA to Costa Rica and want to only use it for Wi-Fi how?

Check with your cellular provider to see if your phone will incur charges just by being on. If no, you avoid charges by simply not making or receiving any calls and only use then phone when it is connected to the Internet via Wi-Fi.

You can go to settings, cellular and turn OFF Cellular Data. (Alternatively, you could technically just turn off Data Roaming)

However, your phone would still receive phone calls in the scenario. If your phone rings, EVEN IF YOU DO NOT ANSWER, you will be charged when the call goes to voicemail. You will be charged minutes while the caller is hearing your outgoing message, and also while they are leaving a message.

Only way to fully avoid this would be to remote the SIM card. If you have a Verizon iPhone or a model that will not work in Costa Rica, then you would not have to worry about that because it won't get a signal.

Before you leave, be sure to download, activate, and TEST the VONAGE app. It's free. It will allow you to make calls back to the USA for free over Wi-Fi. That's my main mode of calling home when I'm there.
