The second way is to set your phone to forward all calls (aka unconditional call forwarding) to a US number before you leave.
There is also a 3rd way:
- Cancel all call/voicemail forwarding (using the call forwarding menu or dialling ##002#)
You will then have a choice of either rejecting the call (by pressing the END/NO button), or letting it ring until the caller hangs up. There will be no charge to either yourself or the caller for either option.
