Not at all, frequent flyer! Your eSIMFlyer plan is exclusively for data, meaning it doesn't come with a new phone number. Your existing WhatsApp account, including all your flight crew chats, family groups, and contacts, will remain exactly as they are. You can continue sending messages and making calls via WhatsApp without any interruption. Just remember, if the app prompts you to update to a new number, simply decline to keep your current ID.
