Can I enable call forwarding on my existing American cellphone after I travel out of the country?
Since your American cellphone will most likely not have coverage in the foreign country that you are traveling to, it may become impossible to enable call forwarding after boarding the plane. Most American cellphone providers will not allow you to change call forwarding by calling their customer service center. Some carriers charge you roaming fees if you activate your call forwarding while abroad. Therefore, you are advised to setup your call forwarding on your American cellphone just prior to boarding your plane.
