Utilizing your cell phone for calls, texts or data while in another country can be expensive without an international plan set up in advance. To avoid unintended and costly charges, plan in advance for an international package or turn your phone completely off or in airplane mode while traveling internationally.
Passports have an expiration date. Of course, your passport must be valid for the extent of your international trip. However, many countries also require that your passport be valid for a period of time following your trip (e.g., 6 months). Check the requirements of your international destination and your passport expiration date well in advance of your trip.
