Not at all, your WhatsApp identity remains unchanged! eSIMFlyer plans are data-only, meaning they don't assign you a new phone number. Your WhatsApp, along with other messaging apps like Line or WeChat, will continue to operate with your original number, keeping all your contacts and chat histories intact. If an app prompts you about updating your number, simply select to keep your current one. It’s all about maintaining continuity while you travel.
