9. Ignoring to check the plan of your mobile phone
To avoid being charged fees for data roaming, you have to check the plan of your cell phone. If the plan doesn’t permit data roaming, you can put off your data immediately before you board the plane. Turn your phone to airplane mode (The phone can still connect to any Wi-Fi). If you need data desperately consider purchasing a plan such as an international plan or rather you can purchase a SIM locally as soon as you reach your destination. As another option, Americans can consider making T-Mobile their carrier. T-Mobile subscribers now have access to data in close to 200 countries and this has enhanced their travelling experience (Note: T-Mobile is not affiliated to us and our monthly plans are paid for by us).
