No, your messaging app identity remains unaffected. DataESIM provides a data-centric service, which means it does not provision a new phone number. Your existing WhatsApp, Telegram, or Signal account, along with all associated chat histories, groups, and contacts, will function seamlessly using your original number. If a messaging application prompts an update to a new number, ensure you decline to maintain your current profile.
