No, your WhatsApp number will remain exactly the same. Truly Roaming eSIMs are designed for data connectivity only, meaning they don't alter your primary phone number. You'll keep all your existing chats, groups, and contacts without interruption. If WhatsApp prompts you about a number change upon inserting a local physical SIM later, simply decline to keep your original number linked to your account.
