I'm traveling overseas and I wish I had a regular iPod touch so that I can just use WiFi to check emails without paying a roaming fee. I have an iPhone with an AT&T sim card. I was wondering if I could remove the sim card and turn it into an iPod touch without having to pay a roaming fee? Does the phone still know it belongs to me even without the sim card?
You can use your iPhone's Wi-Fi without a SIM card, no matter where you are.
If you still want to be able to make calls, but avoid celluar data (data roaming) you can choose to disable just this feature.
You can get further information from Apple's support website at iPhone and iPad: Using cellular networks while in another country.
If you do not have an international data plan, turn off Cellular Data and/or Data Roaming to avoid data roaming charges:
- iPhone: Tap Settings > General > Network
- iPad: Tap Settings > Cellular Data
When data roaming and cellular data are off, you should not see a cellular-network indicator in the status bar.
