Can I Keep My WhatsApp Number with eSIM?

Yes! Your WhatsApp stays linked to your home number even while using a travel eSIM for data.

Absolutely yes. Your WhatsApp number is tied to your original phone number, not to your current SIM card.


πŸ”‘ How It Works

  1. WhatsApp Registration: When you first set up WhatsApp, it verifies your phone number via SMS.
  2. After Setup: WhatsApp uses internet data to send/receive messages, not SMS.
  3. With Roamiya: Your travel eSIM provides the internet. WhatsApp continues working with your original number.

βœ… Best Practice: Dual SIM Setup

For the smoothest experience:

  • Physical SIM (Home): Keep it active for SMS verification codes and emergency calls.
  • eSIM (Roamiya): Use for all mobile data (WhatsApp, Maps, Instagram).

This way:

  • WhatsApp works perfectly.
  • You can still receive bank OTPs and verification texts.
  • No expensive roaming charges on data.

⚠️ What about SMS OTPs?

Some apps (banking, 2FA) send verification codes via SMS. With your home SIM still in the phone, you'll receive these normally, even abroad.

Note: If your home carrier blocks SMS abroad, you may need to contact them or use app-based authentication (like Google Authenticator) instead.


Need to Transfer WhatsApp to New Number?

That's a different process (Settings > Account > Change Number). But for travel, you don't need to change anything!
