Question

What do I do if my SIM card is blocked if I got it from an overseas carrier?

Community Answer

When it says your SIM card is blocked, it most likely means that your phone is locked and you need to call your carrier to have it unlocked. See Method 2.

Question

If I'm traveling to Israel, how can I switch from airplane mode to Wi-Fi without being charged for any data downloads or messages received in between the few seconds to a minute it connects with Wi-Fi?

Community Answer

You can still access Wi-Fi with your data turned off. Just turn off your cellular data on your device.

How can I call the United States when traveling to Israel?

If your phone is from the US, you usually don't need to add a number before the phone number you're calling.

Question

If I connect to the wi-fi on a cruise ship using my mobile phone, will I get charged for using email?

Community Answer

You absolutely won't. You only get charged by your mobile carrier for data transferred over their network. Data transferred over WiFi does not count against your mobile data cap, because it's not transferred over your mobile carrier's network.

Only if you have network connectivity while you are roaming internationally, for which you might need to add the international roaming pack.
