For Ukraine, we strongly recommend activating your eSIM On Trip before you even cross the border. Since air travel is restricted, you'll likely be entering via a land route, perhaps from Poland or Romania. Having your data live immediately upon entry is crucial for navigation, staying updated, and contacting loved ones. Don't wait until you're already there – get sorted in minutes before you depart!
