Itinerary
Yes, you can! However, please keep the following in mind:
- Set Up Your SIMs Properly: Use your primary SIM for phone calls and SMS, while the Vietnam eSIM should be set for mobile data.
- Disable Auto Data Switching: If your phone has an "Auto Data Switching" feature, turn it off to prevent unintended data roaming charges on your primary SIM.
- Roaming Charges Apply: International roaming fees may be incurred for calls and SMS sent via your primary SIM.
💡 Tip: Keep your primary number active only when necessary to receive calls and SMS in Vietnam. Otherwise, use apps like WhatsApp, Messenger, or Viber to fully utilize the eSIM's unlimited data and stay connected with family and friends.
