Tips for Choosing
When in doubt, go one size up — It is better to have leftover data than to run out mid-trip
Wi-Fi counts — If your hotel has reliable Wi-Fi, you will use less mobile data
Unlimited plans — If you plan to stream video or share your hotspot, consider an unlimited plan for peace of mind
