Question: Hello, we will be traveling in Australia this July. Can we call from a US-based cell phone to a US-based cell phone while in Australia?
If one of your cell phone numbers is (212) 555-1234, dial 0011-1-212-555-1234 to call the cell phone. You can also dial the call as +1-212-555-1234 (some phones can dial a plus symbol).
Be aware that this call will be expensive. You will be incurring the cost of an international call from Australia to the US when you dial out from the first phone and an additional international roaming call from the US to Australia as the second phone receives the call. Be sure to check your international and roaming rates before making these calls.
