Most Vuoly plans are data-only: they include internet access and do not include a phone number, minutes, or SMS. Some plans do include calls and texts; when they do, the plan's details page says so. If calls are not mentioned in the plan details, the plan is data-only.
Either way, a data plan covers almost everything you do while traveling, including maps, browsing, email, and calls and messages over apps like WhatsApp and FaceTime.
Calls and texts on data-only plans
Your home number stays on your regular SIM, so you can still receive calls and texts on it while abroad. Your carrier's roaming rates may apply.
With WiFi Calling turned on, you can use your home number over the internet instead. See: WiFi Calling for travelers.
Bank verification codes
Codes sent by SMS arrive on your home SIM, not on a data-only eSIM. To receive them, keep your home line on with roaming available, or use WiFi Calling.
Codes sent through an app or push notification work over your Vuoly data with no extra setup, as do WhatsApp codes.
Tip: before you travel, check which of your accounts still use SMS codes and switch them to app-based confirmation where possible.
