4 Consider Getting a Personal Wi-Fi Device
If you don’t want to sign up for a costly international calling plan, a second option is to get a personal Wi-Fi device or “Pocket Wi-Fi”.
Personal Wi-Fi devices act as your own hotspot and provide data to your laptop or smart devices, and can often be rented at your destination’s airport. Plus, they can be turned on or off at will, which allows you to be in control of your usage.
A major advantage to choosing a personal Wi-Fi device over an international SIM card is that you don’t have to switch local SIM cards if you are traveling between countries. Also, personal Wi-Fi devices can be cheaper than select international plans, especially if your carrier chargers specific rates depending on the country.
